2 Rhythm™ RT User’s Guide



2.1 System Preferences

To set up the Rhythm RT system for image receipt and transmittal, use the System Preferences form.

Figure 2: System Preferences Form

2.2 Destinations

These settings are necessary for communication with your Rhythm Review workstation(s). See your Rhythm Review User or Reference Guides for information on setting/getting the address information.

Multiple Destinations can be added to Destinations list, but only one Destination is activated at a time by checking the checkbox of the Destination. To add a Destination in the Destinations list, click on the Add button to bring up the Review Station form (Figure 3 on the next page). On the Review Station form, you must enter the values of the Destination Host Name, Destination AE Title and Destination Port, based on the Rhythm Review workstation settings.The Destination IP Address is automatically populated after the Destination Host Name is entered. If there are multiple IP addresses associated with the Destination Host Name, the first IP address will be selected by default.

To remove, edit or test a Destination in the Destinations list, select the Destination you want to remove, edit or test and click on the Remove, Edit or Test button respectively.

The Destination AE Title and Port must match that which is typed in the Rhythm Review workstation. (On Rhythm Review, go to the menu Configuration>Generic>DICOM tab.)

Note: The CR Tower defaults to Port 104, which is also the default on the Rhythm Review workstation. Please change the Rhythm Review and your Destination Port to another number, such as 105, when using the Tower.



2.2 Destinations (cont.)

Figure 3: Review Station Form

2.2.1 Default Value for Study ID

The Study ID is used as one portion of the three fields that make a “study” unique in Rhythm Review. The Component ID, Component Name and Study ID combination makes a unique study. So, if a date-time is used for the Study ID, then every scan within that component will be within that one study.

Note: Moving from one component to another within the component grid will cause the study-ID to refresh to a new date-time.

But the next time that component type is selected again and rescanned, a new date-time stamp will be applied, so the new scanned images will go into a new study.

By entering a unique identifier (such as the serial number for the part in the study-ID field, when that same part is scanned again, the new scans will be attached to the original study, in a new series. If no serial number is applicable, but the organization of the images within studies is still desired, then a default value can be put into the Study-ID field which will produce a similar result. For example, if always examining the same pipe at a certain location, then that Component ID, Component Name and a default Study-ID of one will produce a series of images taken at each date/time for that pipe all within one study.

IMPORTANT: Once the study is archived off of the Rhythm Review station, any new scans with the same Component ID, Component Name and Study ID will still be created into a new study, as the original on the Local Rhythm Review workstation is not available to receive additions.

2.2.2 Date-Time Stamp

When choosing the Date-time Stamp setting, the Study ID tag will be automatically filled with the time-date stamp of the point in time that the user clicked on a component. The user can still change the Study ID tag if he/she wishes, after the tag was automatically filled.



2.2.3 Custom Text

When choosing the Custom Text setting, the study ID tag will be automatically filled with the custom text entered here. The user can still change the Study ID tag if he/she wishes to after the tag was automatically filled.

2.2.4 Low Disk Space Warning

This setting will alert the user if the disk space where the images are acquired is less than the Minimum Space setting in the form above. The alert will be activated every Time Interval setting in seconds.

2.2.5 Logging

Here the user can enable the Send Logging option. If it is selected, enter the desired purge increment.

2.2.6 Theme

The user has two options:

The acquisition application will allow a System Administrator to enter and save techniques.

Techniques are broken into two separate sections:

• Component Information — This is where an Administrator defines the component and gives descriptive information for that component.

• Technique Information — The Administrator can enter multiple techniques (setup information, such as: kV, mA, exposure time, etc.) for each component type.

Figure 7: Components and Techniques

This technique information can then be associated with a captured image in the resulting DICOM image file header, where it will be stored with the image.

4.1 Overview

Film Digitizing is a standard process that allows scanning of existing static images so that the images can be stored, manipulated, or transmitted in digital format.

The FS50 film digitizer is an instrument designed to convert radiographic film to high quality digital images at 12 bit resolution, The 2905 Laser film Digitizer is extremely fast, scanning a 14 X 17 film to 2K resolution in a mere 7 seconds. With advanced laser and superior optic technologies, the 2905 is perfectly suited to scan all of your department’s images, regardless of the challenges your studies present.

4.2 System Requirements

• Windows 2000 or Windows XP operating system.

• LSDT environment installed.

• ASPI driver installed.

Note: LSDT version must be 2.5 or higher.

4.3 System Operation

The FS50 can operate with standard film sizes, custom film sizes or roll film. The measurement units used for this scanner can be specified in the Configuration form.

Interfaces SCSI, SCSI II, Twain



4.5 Scan Operation

Note: Be sure that the FS50 has been selected as the Active Scanner from the list on the Preferences item, in the File menu.

4.5.1 Pixel Pitch

The pixel size of the image can be set from 50 microns to 2000 microns per pixel. The Acquire interface provides five preset pixel pitch (50 – 200 microns) and the option to input a Variable pixel pitch. When the Variable pixel pitch is selected, a desired pixel pitch must be specified.

If Roll film is selected, the Maximum Height of the image is recalculated when a new pixel pitch is entered. Rhythm RT will calculate the Maximum Image height from this information. The maximum Image height is based on the following limitations:

• The number of Lines per Image cannot exceed 32767. (Note: the number of lines depends on the pixel pitch selected.)

• The size of the Image file cannot exceed 128 MB.

If Single film is selected, the maximum image height will NOT change, but the size of the image saved to the media will change.

4.5.2 Scan Mode

Scan mode represents the quality of the scan. There are three (3) modes available:

• High Speed mode: Each line is scanned only once, and no averaging will be calculated.

• High Quality image mode: Each line is scanned four times and the average value will be sent over to the Rhythm RT system

• Normal mode: Each line is scanned two times and the average value will be sent over to the Rhythm RT system

4.5.3 Scan Type

The Scan Type indicates whether a single sheet of film or roll film is being scanned.

4.5.4 Single Film

The height of the image is calculated automatically based the width of the film sensed by the scanner according to the table above (as listed in “Technical Specifications” on page 21).



4.5.5 Roll Film

The user will scan a roll of film of an unidentified height, and the user will specify an image height; this segment will be scanned and saved in one file and sent to the Acquire system, then the next segment will be scanned and saved in a separate film. The system will continue to scan the same image height the user entered until it detects the end of film.

After each segment has been scanned and saved, Rhythm RT will reverse the film by some N value mm (indicated in the GEDI_FS50.ini file) and start the next scan. This ensures no portion of the film is overlooked.The maximum height of the image is calculated based on the pixel pitch and the width of the film inserted into the scanner.

4.5.6 Scan, Cancel Scan and Eject

• The Scan button will start a scan.

• Cancel Scan button will cancel the scan and reverse the film back to the start position in the input tray of the scanner.

• Eject Scan button will cancel the scan and eject the film to the output (top) tray.

4.6 Properties

This form displays the scanner Firmware description.

Figure 20: FS50 Scanner Properties Form







6.1 Overview

Computed radiography (CR) is a well-established process for capturing digital radiographic images. The SCAN X scanner is an instrument designed to scan phosphor plates and produce high quality x-ray images over a wide dynamic range with a high signal-to noise ratio.

This is accomplished by illuminating the screen with a laser beam, as the screen is moved perpendicular to the laser. The emitted light is collected, converted to an electrical signal and digitized to provide a 16-bit resolution image.

A laser beam discretely illuminates each point (pixel) on the film. As a result, the resolution and densities in the digital image are representative of the original radiograph.

6.2 Scan Options

Note: Be sure that the CR50P\CRx25P has been selected as the Active Scanner from the Active Scanner list on the toolbar of the main form.

Figure 22: Selecting CR50P in the Preferences Item

6.2.1 Basic (Preset) Mode

There are eight optimized setting modes from which to choose in a dropdown. Unlike the Advanced Mode described below where resolution, gain and a calibration file must be chosen first, this Mode (Figure 23 on page 27) has preset values and an associated Calibration file for each mode. Simply select a mode and scan.

1. Corrosion Mode: IPC2, 134mu pixel, IR192 - 50% D7, X-ray 25% D7 2. General Purpose: IPS, 100mu pixel, IR192 - 100% D7; X-ray 50% D7 3. Weld: IPS, 50mu pixel, IR192 - 50% D4 4. Weld small WT: IPU 25mu pixel, SE75 - 100% D4

5. Bam Certified: IPS - 50mu pixel 6. Bam Certified: IPU - 25mu pixel 7. Quality: IPS - 67mu pixel 8. Quality: IPS - 33mu pixel

2. Xml files provided for the preset will be placed in the AppModeFiles folder located one folder below where Rhythm is installed. The calibration files that are created for each mode shall be renamed to the same name as the Application Mode found in the dropdown, with the .kor suffix. e.g.,



6.2.1 Basic (Preset) Mode (cont.)

Xml files provided for the preset will be placed in the AppModeFiles folder located one folder below where Rhythm is installed. The calibration files that are created for each mode shall be renamed to the same name as the Application Mode found in the dropdown, with the .kor suffix, e.g.,

6.2.2 Resolution Setting Advanced Mode

The Resolution of the image can be set from a drop down menu that has the items listed below and in the window shown in Figure 24 on page 28.

Whether selecting one preset in Basic Mode or each of the following - Resolution, Gain and a Calibration File in Advanced, an Initialization or INI file (Figure 25 on page 28) will be created.

• 17 Microns - 29.15 lp/mm (Only available on CRx25P Scanner)

• 25 Microns - 19.82 lp/mm (Only available on CRx25P Scanner)

• 40 Microns - 12.5 lp/mm







• 250 Microns - 2 lp/mm

When the user selects a resolution setting, the information frame will display the current speed of the scan and the maximum pixel value for the current resolution setting



6.2.2 Resolution Setting Advanced Mode (cont.)

Figure 24: Advanced Tab

Figure 25: Information File



6.2.3 Gain Setting

The gain of the scanner is set from the drop down menu on the GUI. The gain setting represents the voltage setting of the PMT.

There are three gain settings for the SCAN X scanner:

• High Gain

• Medium Gain

• Low Gain

6.2.4 Calibration File Selection

In order to proceed with a scan, the user must select a calibration file (If a calibration file is not selected, Rhythm RT will prompt the user to choose a calibration file to proceed.) This calibration file must:

• Be created using the proper utility described below

• Have the same serial number as the serial number of the scanner attached to the system

• Have an extension of “kor”

The user should select the directory where the calibration file(s) are located. All the calibration files in the directory chosen will appear in the drop-down menu in the calibration frame. The user should choose the proper calibration file from that list.

Figure 26: Calibration File Directory



6.3 Scanner Modes

6.3.1 Scan Mode

To initiate a scan:

1. Press either SCAN or Continuous SCAN. The scanner will set up with the current settings (Status - Waiting for plate)

2. The user should place the plate on the scanner and slide it into place. The scanner will start to scan (Status - Scanning), and the image will be processed (Status - Processing data.)

3. Once the image is fully acquired (Status - Connected), the plate will be ejected from the scanner.

4. If the SCAN button was used, then the scanner will be reset for the next scan. If the Continuous SCAN button was selected, then the scanner will wait for the user to insert another plate.

Note: If the acquired image has some pixels with values over 200 and some under 200, then the pixel values under 200 will be raised to 200.If the acquired image has all values of the pixels under 200, then the image will be disregarded and the user will be given a message indicating that the exposure was not high enough to be recorded as an image.

6.3.2 Cancel Mode

When the user clicks the Cancel Scan button, the plate will continue to be pushed out of the scanner in the same speed as the scanning speed; then the scanner will reset.

The user can click Cancel SCAN at any time to cancel the current scan.

6.3.3 Ejecting a Jammed Plate

In the case of a jammed plate inside the scanner, the user can repower the scanner and hit SCAN on the interface; this procedure will eject the plate from the scanner.



6.4 Advanced Options

The Advanced Options button is only available for the user with the administrative rights to the Rhythm RT Utility. Please refer to this manual on how to set up administrative access to users for the Rhythm RT utility.

• When the user clicks on the Cancel button, the Advanced Options window will close and the user would lose all the modifications that he/she did on that window.

• When the user clicks on the Reset button, all the values on that window will reset to their original values that were there when the software was installed on the system.

• When the user clicks on the Save button, the Advanced Options window will close, saving all the values that the user modified when that window was open.

Figure 27: The Advanced Options Window



6.4 Advanced Options (cont.)

The Advanced Options window contains several subwindows:

• Calibration

• Calculate image size

• Eraser setting

• Power and Speed options

• Gain setting

• Advanced scanner options

• Customer Parameter File

• Scanner Info and Parameter Template

6.4.1 Binning Feature

This subwindow contains a checkbox marked Binning on.

Figure 28: The Advanced Scanner Options

When this checkbox is checked, binning will be turned on. Binning will result in a pitch of the plate transport that is only half of the pixel size; i.e. the pixel size in the direction of the scanning laser spot (fastscan) will be kept constant, but the pixel size in the direction of the plate transport (slowscan) will be half of that in the fastscan direction. Subsequent 2x1 binning results back in square pixels of the originally selected size.

This binning option is useful to avoid undersampling when a pixel size is selected that is larger than the basic spatial resolution of the image plate/scanner combination, e.g., pixel size >40 µm for IPU and pixel size >80 µm for IPS. The Binning option will result in a better SNR value, but also in a lower throughput.



6.4.2 Customer Parameter File

Figure 29: Customer Parameter File

This subwindow allows you to select and view a custom parameter file. This file contains custom parameter settings that will override the selected parameters. The custom parameter file is XML file (extension .xml).

Several files are included in the installation. The included files are intended for situations that require horizontal and vertical sizes to be exactly equal, e.g., for compliance with EN14784-1.

Clicking Browse will open a folder, “bam_templates”, containing these files.

Figure 30: bam_templates folder

The 25mu and 50mu pixel size correspond to the modes that were BAM certified. Two additional pixel sizes, 40mu and 100mu, are also included. For each pixel size, there are 3 files corresponding to low gain (450pmt), medium gain (600pmt) and high gain (800pmt).

Clicking on a specific file will select this file. Selection is finalized by clicking on Open, then the window closes automatically. The selected file may be viewed by clicking on View. This will open the XML file and the customer parameter settings may be inspected.



6.4.2 Customer Parameter File (cont.)

Clicking on Save will save the customer parameter set and these will override all previously selected parameters.

The creation of a calibration file for the scanner is a sensitive operation that requires extensive CR experience. Please read carefully the calibration instructions when attempting to calibrate the scanner.

When the user clicks the Calibrate Scanner button, the calibration instructions will appear; when the user clicks the Done button, the calibration utility will launch.

Figure 32: The Calibration Utility

The user should choose option number one, then slide the exposed plate into the scanner. When the plate is scanned, the utility will ask the user to press any key to proceed. When the calibration is done, the utility will display the final result.

If the calibration is successful, the utility will ask the user to set the calibration file current. If the calibration is not successful, the utility will display the reason for failure, which could range from a noisy image to an overexposed or underexposed plate.

After a successful calibration, the calibrated file will be saved in the same directory as Rhythm RT or the scanx_dlls\Version60 or scanx_dlls\Version61 folder in the Rhythm RT directory, depending on what scanner type is used. The format of the calibration file will be as follows:

<Serial Number of the Device> <Space> <Year - Month - Day> <Space> <Hour - Minute - Second> <.kor>

Example: AP000113 2006-12-15 10-23-46.kor

On connection to the scanner, the Scan button is enabled. To start a scan, place a plate into the scanner tray and click the Scan button.



8.4 Scan Settings

• Scan Resolution — Select either 35 micron or 70 micron scan resolution; or use the Default selection. Any adjustments to this parameter will be applied on the next scan.

• IP Sensitivity— IP Sensitivity of the scanner can be adjusted from a range of 100 to 10000. Any adjustments to this parameter will be applied on the next scan.

• Plate Detection — Select this option to autodetect any plates that are present in a parallel scan scenario.

• Linearize Data — Select this option to apply linearization to the scanned image.

• (Re)Start Server and Stop Server Buttons — These buttons are required when any IP address or port numbers are to be modified. Before making any changes you need to press Stop Server and continue to make changes in the setting. Once all the changes are done, you need to press the (Re) Start button to reflect the changes.

• Scan — Initiates the scan process.

• View Connection Status — Connectivity status with the scanner is available through selection of the View Connection Status option. It provides a detailed accounting of the transmission of messages between the scanner and the Rhythm acquisition software. This information is also logged to a file and can be used to diagnose issues with connectivity.

• Scanner Communication Settings — By default the RT/RT Lite Software is configured to operate on the IP Address: 192.192.192.193 and Port 104. If another software program is currently using the same port or IP Address, a user can use the Scanner Communication Settings option to set a new Dicom Port or IP address. Rhythm Review, by default, uses port 104. If Rhythm RT/RT Lite and Review need to work together, you must change the Scanner port number to other than 104.

• Display Open Folder— This setting is used for support purposes to open images received by the scanner in case there is some problem with the load of images received from scanner. It is not recommended for use outside of support purposes.

• Apply Horizontal Flip Image— This setting is used to store the image in proper way. As the image would be displayed as horizontal flip without this option, this option corrects the horizontal flip.



8.5 Error Handling

Rhythm RT/RT Lite software is capable of handling error conditions such as network connection errors and partial images from scanners. Once the scanning starts, RT/ RT Lite receives the image. If the scanner gets disconnected from the network for 60 seconds, RT/RT Lite displays the following message.

Figure 37: Connection Error Message

You can troubleshoot the connection and correct it. Click Retry. RT/RT Lite waits for another 120 seconds.

If the troubleshooting is successful, RT/ RT Lite starts receiving data. It will flash the message in the Communication Information message box (Figure 38 below) and the error dialog will close without any user input.

Figure 38: Communication Information — Data Receipt Message

If you fail to troubleshoot properly or click Cancel, scanning is aborted. If no data is received in the next 120 seconds, then RT/RT Lite displays the message in Figure 39 below and the scan is aborted.



8.5 Error Handling (cont.)

Figure 39: Aborted Scan

Even if the troubleshooting was successful, it is possible that the received data is not conforming to a complete image. In this case RT/RT Lite displays the message in Figure 40 below and waits for another 60 seconds to receive remaining data from scanner.

Figure 40: Communication Information — Scan Is Incomplete




After waiting to receive the remaining data again, a conformance check will be done to validate the received image. If the conformance check again fails, RT/RT Lite displays the message in Figure 41 below and aborts the scan.

Figure 41: Aborted Scan

If the conformance check was successful, Rhythm RT starts the Post Scan Process.



8.6 Post Scan Process

On receipt of image data from a scanned plate, the Rhythm acquisition software checks the integrity of the data and then presents a dialog that can be used to tag editable DICONDE fields and also crop the image into smaller images of interest.

Figure 42: Post Scan Process

The image will be displayed in the viewport. If the Plate Detection option was selected in the scanner interface discussed above, there may be ROIs which are positioned in the image correlating to the edges of any plates that are present in a parallel scan scenario. Further, the ROIs will be listed in the list to the left. If more cropping areas are desired, click the Add button. An ROI is added to the viewport that can be moved and sized as necessary. ROIs that are not correctly placed can also be removed from the image by clicking the Delete button. DICONDE tag management is done on a per ROI basis (unless there are no ROI's positioned in which case they are just applied to the full image). The Component Name, Component ID and Study ID DICONDE tags are editable in Rhythm RT/RT Lite. These fields are pre-populated by the technique database. The Series Desc and Image Comments fields are also editable per ROI. For Rhythm RT Lite also allows for the naming of the final name to be populated in the image list. On completion of ROI adjustment and DICONDE mapping, save images to the Rhythm acquisition system by selecting Save All Images. You can close the dialog by selecting the Close option when completed.

Note: Be aware that the scanner acquisition window will be cleared when you close the dialog!

10.1Rhythm DXR

The DXR X-Ray Inspection System (to be identified as the “DXR System” for the purposes of this section of the user’s guide) supplies x-ray images (radiographs) of objects that let operators find indications of defects, internal configuration, and morphology.

Figure 53: The Rhythm DXR X-Ray System

The detector of the DXR system is an imaging device that uses flat-panel, cesium-iodide and gadolinium oxide sulphide detectors that GE developed. High fidelity imaging capabilities are the result. These capabilities are used to supply a complete imaging system for non-destructive industrial inspections. This imaging system has significant benefits in performance and sensitivity compared to conventional film-based or image-intensified radiography. The detector, with its associated data acquisition hardware and software, is the core of the DXR System.

All of the DXR systems provide static images. Some DXR systems, such as the DXR-250RT system, can supply static digital radiography (DR) images, or real-time digital images at 30 frames per second (fps).



10.2Cautions and Warnings

WARNING! The user must make sure that only those personnel sufficiently trained in the use of the GE DXR system and related equipment will operate it . The operators must fully know and understand the operating procedures related to this equipment and supplied in the operation manual.

WARNING! The operators must also fully know and understand the safety recommendations supplied in the operation manual. If not, serious injury to the operator or to other personnel can be the result.

CAUTION! Always use a shield to give protection to the detector from x-rays during the x-ray tube warmup procedure. Excessive exposure to x-ray radiation can cause artifacts in the image and decrease the life of the detector.

10.6Detector Calibration

10.6.1 Calibration

Rhythm RT supports two types of Pixel Calibration:

• Manufacturer recommended calibration —This method of calibration is based on the custom algorithms developed by General Electric for the specific detector type being calibrated. GE Measurement & Control recommends that its customer base use this calibration method, as it is developed specifically for this type of detectors.

• ASTM Calibration method — Using this method of calibration is based on the algorithms developed by the ASTM committee according to E2597-07. This calibration is meant to be used as a general guideline and a comparing tool. GE Measurement & Control recommends that its customer base use the “Manufacturer recommended” method of calibration.

Rhythm RT supports two methods of calibration:

• Manual Calibration — In this mode, Rhythm RT will not be communicating with the X-ray controllers. The user must set up the exposure techniques on the x-ray controller manually. To use manual calibration:

1. Log on to Windows as an Administrator.

2. Start Rhythm RT.

3. Select Rhythm DR, and enter Administrative Options (Figure 67 on page 68).

4. Select the General tab

5. Uncheck the Link to X-ray Controller.

6. Uncheck the Link to Shutter Controller.

• Automated Calibration — In this method Rhythm RT will communicate with the X-ray controller and the Shutter controller if they exist. Rhythm RT will set up the X-ray controller settings based on the user entries in the “Calibration Exposure settings” in the Admin options of Rhythm RT (figure 49f). The mA and kV settings entered by the user should correspond with the X-ray exposure settings that would bring the detector just below its saturation value. The saturation value for the detector varies; however, it is generally above 13000 pixel value count.

To use automated calibration:

1. Log on to Windows as an Administrator.

2. Start Rhythm RT.

3. Open the Preferences form, and select the proper X-ray controller and shutter controller (figure 49g).

4. Select Rhythm DR, and enter the Admin options (Figure 80).

5. Select the General tab.

6. Check the Link to X-ray Controller.

7. Check the Link to Shutter Controller.

8. Enter the proper exposure settings (Figure 81) so that the detector can achieve a level just before saturation.

10.6.1a Manufacturer Recommended Calibration (cont.)

1. To begin, turn off X-rays (Figure 84 below). The Acquisition window opens (Figure 85 below).

Figure 84: Turn Off X-rays Window

Figure 85: Acquisition Screen

Rhythm RT will take three acquisition sequences while the X-rays are turned off (Dark Shots):

• One Frame for “Offset Dispersion Short” test

• Sixteen Frames for “Offset Dispersion Long” test

• Three Frames for “Light Lo Offset Shots” test




2. Start the X-rays Acquisition at one third of the exposure level necessary to reach the detector saturation levels.

Figure 86: Pixel Calibration Creation Window

If you have selected Link to X-ray controller in the Admin menu, then the X-rays will start automatically, and the window above will not appear.

When the X-rays start and stabilize, click OK (Figure 86 above). A four-frame acquisition will occur, called “Light Lo air shots.”

After the acquisition window automatically terminates, the program performs several calculations (Figure 87).

Figure 87: Calculation Window

Rhythm RT will measure the average pixel value of the middle 200 x 200 pixel of every image acquired to be called “Average pixel value per image”. The program then calculates the average of the “Average pixel value per image” for all the images acquired in a calibration sequence, and labels it “Average Pixel Value in the center of the detector”. Rhythm RT will display a message if the “Average Pixel Value in the center of the detector” is below or above a set value, based on the type of detector.

3. You can repeat the last acquisition step, cancel the calibration, or continue to the next step despite the warning.

If you have enabled the automated calibration option, then after the termination of the acquisition window, another acquisition window will appear.

A 16 frame offset acquisition will occur. This acquisition is called “Light Med offset shots.”




4. If the automated calibration is disabled, then Rhythm RT will ask you to start the X-ray at two-thirds the exposure settings needed to reach detector saturation levels; if not, then the PC will automatically start the X-rays at two-thirds of the mA input on the Admin options.

A 16 frame Air acquisition will occur. This acquisition is called “Light Med Air shots.”



Rhythm RT will measure the average pixel value of the middle 200 x 200 pixel of every image acquired, called “Average pixel value per image.” Then the program calculates the average of the “Average pixel value per image” for all the images acquired in a calibration sequence, called “Average Pixel Value in the center of the detector”.

5. Rhythm RT will display a message if the “Average Pixel Value in the center of the detector” is below or above a set value based on the type of detector. You must repeat the last acquisition step, cancel the calibration, or continue to the next step despite the warning (as shown in Figure 88 above).

If automated calibration option is enabled, then after the termination of the acquisition window, another acquisition window will appear.

A 3 frame offset acquisition will occur. This acquisition is called “Light Hi offset shots”.

6. If the automated calibration is disabled, then Rhythm RT will ask you to start the X-ray at the exposure settings needed to reach detector saturation levels; if not, then the PC will automatically start the X-rays at the mA input on the Admin options

A 3 frame Air acquisition will occur. This acquisition is called “Light Hi Air shots”. After the acquisition window automatically terminates, the program performs several calculations (Figure 89 on the next page).





Rhythm RT will measure the average pixel value of the middle 200 x 200 pixel of every image acquired, called “Average pixel value per image”. The program also calculates the average of the “Average pixel value per image” for all the images acquired in a calibration sequence, called “Average Pixel Value in the center of the detector”. Rhythm RT will display a message if the “Average Pixel Value in the center of the detector” is below or above a set value based on the type of detector.

7. You must repeat the last acquisition step, cancel the calibration, or continue to the next step despite the warning.

Once this step is complete, the summary window appears as shown in Figure 90 on the next page.

3. Start the X-rays Acquisition at one-half (50%) of the exposure level necessary to reach the detector saturation levels.

Figure 94: X-Ray Acquisition Window

Note: If Link to X-ray controller is selected from the Admin menu, then the X-rays will start automatically, and the window above will not appear.




4. When the X-rays start and stabilize, click OK.

A 120 second series of acquisitions will occur. This acquisition is called “ASTM_50P”. After the acquisition window automatically terminates, the program performs several calculations (Figure 95).


Rhythm RT will measure the average pixel value of the middle 200 x 200 pixel of every image acquired, described as “Average pixel value per image”

Rhythm RT will calculate the average of the “Average pixel value per image” for all the images acquired in a calibration sequence, called “Average Pixel Value in the center of the detector”.

Rhythm RT will display a message if the “Average Pixel Value in the center of the detector” is below or above a set value based on the type of detector.

5. You can repeat the last acquisition step, cancel the calibration, or continue to the next step despite the warning. If automated calibration option is enabled, then after the termination of the acquisition window, another acquisition window will appear.

6. If the automated calibration is disabled, then Rhythm RT asks you to start the X-ray at 10% of the exposure settings needed to reach detector saturation levels. If not, then the PC will automatically start the X-rays at 10% of the mA input on the Admin options.

A 120 second series of Air acquisitions will occur. This acquisition is called “ASTM_10P”.

After the acquisition window automatically terminates, Rhythm RT will measure the average pixel value of the middle 200 x 200 pixel of every image acquired, described as “Average pixel value per image”.

The program will calculate the average of the “Average pixel value per image” for all the images acquired in a calibration sequence, described as “Average Pixel Value in the center of the detector”. Rhythm RT will display a message if the “Average Pixel Value in the center of the detector” is below or above a set value based on the type of detector.





8. If the automated calibration option is enabled, then after the termination of the acquisition window, another acquisition window will appear. But if the automated calibration is disabled, then Rhythm RT will ask the user to start the X-ray at the exposure settings needed to reach 80% of the level needed to reach the detector saturation level. If not, then the PC will automatically start the X-rays at 80% of the mA input on the Admin options.

A 120 second series of Air acquisitions will occur. This Acquisition is called “ASTM_80P”


Figure 96: Calculations Window

Rhythm RT will measure the average pixel value of the middle 200 x 200 pixel of every image acquired, called “Average pixel value per image” Then the program calculates the average of the “Average pixel value per image” for all the images acquired in a calibration sequence, called “Average Pixel Value in the center of the detector”.

Rhythm RT will display a message if the “Average Pixel Value in the center of the detector” is below or above a set value based on the type of detector.


10. If you are satisfied with the acquisition, keep the power ON to the detector, and turn off X-rays. Then wait for 30 minutes under the previous conditions. The 30 minute wait allows you to adhere to the E2597-07 Specification of the ASTM standard.

11. Once the 30 minutes expire, click the Continue button. A 120 second series of Offset acquisitions will occur, called “ASTM_LagOffset”.

12. If the automated calibration is disabled, then Rhythm RT asks you to start the X-ray at the exposure settings needed to reach 80% of the level needed to reach the detector saturation levels. If not, then the PC will automatically start the X-rays at 80% of the mA input on the Admin options. That acquisition will take 5 minutes (300 seconds) to complete (Figure 97 on the next page).




Figure 97: X-Ray Acquisition Window —Lag 80%

13. When the acquisition sequence is done, do not turn off the X-rays. The following window will appear (Figure 98 below).

Figure 98: Pixel Calibration Window

14. If you are satisfied with the exposure, click Continue. Then turn off the X-rays after 5 seconds, or at the appearance of the first acquired frame, if the frame time is more than 5 seconds. A 70-second series of Air Exposures will start. Once the exposure is complete, Rhythm RT will analyze the frames and display the results in the Summary window (Figure on the next page).




Figure 99: Summary Window



10.6.1c Gain and Offset Calibrations

Gain Calibration is the process where each pixel is calibrated (weighted) so that all pixels shall have very similar values if exposed with the same radiation amount provided that the X-ray tube field is constant and uniform. Offset Calibration is the process where each pixel value is reduced by a value very similar to the value of the average of that specific pixel across a series of similar acquisitions where the detector is not exposed to any form of radiation.

1. To calibrate for Gain offset, click on Create gain and offset table either for Manufacturer recommended calibration or ASTM calibration (Figure 100 below and Figure 101 on the next page).

Figure 100: Calibration Tab with Manufacturer Recommended Calibration Selected

2. Turn off X-rays by clicking OK (Figure 102 below).

Note: If the Connection to X-ray option is checked, then that message will not appear but, the X-rays will be stopped automatically if they are already turned on.

Figure 102: Turning Off X-Rays

A series of 20 frames will be acquired while X-rays are off, called “Offset Calibration Shots”.




3. After the acquisition is complete, a message appears (Figure 103 below), asking you to start the exposure to achieve a value just below detector saturation.

Note: If “Connection to X-ray” option is checked, then that message will not appear, but the X-rays will start automatically at the exposure settings already declared in the “Calibration Exposure settings” section.

Figure 103: Gain Offset Calibration

After the acquisition window automatically terminates, the program performs several calculations (Figure 104 below).

Figure 104: Pixel Calibration Window

Rhythm RT will measure the average pixel value of the middle 200 x 200 pixel of every image acquired, called “Average pixel value per image”. The program will then calculate the average of the “Average pixel value per image” for all the images acquired in a calibration sequence, called “Average Pixel Value in the center of the detector”.

Rhythm RT will display a message if the “Average Pixel Value in the center of the detector” is below or above a set value, based on the type of detector.




4. You must now repeat the last acquisition step, cancel the calibration, or continue to the next step despite the warning. If the automated calibration option is enabled, then after the acquisition window closes, the message shown in Figure 105 below appears.

10.6.2 ASTM Analysis

Click on the Perform ASTM Analysis button to create a bad pixel report based on the bad pixel definition of the ASTM document E 2595-07.

Figure 106: Perform ASTM Analysis Button



10.6.3 ASTM Report

Click on the Show ASTM Report button to show the ASTM report.

This section discusses how the ASTM document E2597-07 “Standard Practice for Manufacturing Characterization of Digital Detector Arrays” classifies bad pixels.

According to section 6.2.1 of the ASTM document E2597-07, bad pixels are grouped as follows:

• Single Bad Pixel

A single bad pixel is a bad pixel with only good neighborhood pixels.

• Cluster of Bad Pixels

• Two or more connected bad pixels are called a cluster. Pixels are called connected if they are connected by a side or a corner (8-neighborhood possibilities). Pixels which do not have 5 or more good neighborhood pixels are called cluster kernel pixels (CKP).

• A cluster without any CKP is well correctable and is labeled an irrelevant cluster. The name of the cluster is the size of a rectangle around the cluster and number of bad pixels in the irrelevant cluster, for example, “2x3 cluster4”.

• A cluster with CKP is labeled a relevant cluster. The name of the cluster is similar to the irrelevant cluster; with the exception that the prefix “rel” is added and the number of CKPs is provided as a suffix, for example, “rel3x4 cluster7-2”, where 7 is the total number of bad pixels and 2 are those in this group that are CKPs.

• A bad line segment is a special irrelevant cluster with 10 or more bad pixels connected in a line (row or column) where no more than 10% of this line has adjacent bad pixels; no pixel in the bad line segment shall be a CKP. The name of a bad line segment will have the word “line” substituted for the word “cluster”, for example, “1x256 Line256” or “2x24 Line26”.

Figure 107 below lists examples of how each pixel can be named and classified according to the ASTM standard E2597-07

10.6.3a Bad Pixel Map Information Section

This section lists the number of clusters in the bad pixel map, and also lists the number of bad pixel in this bad pixel map.



10.6.3b Cluster Details Section

This section lets the user browse through all types and clusters. By selecting a specific cluster, the user can see all the relevant information about the cluster, such as:

• Cluster location (vertical and horizontal)

• Cluster size (vertical and horizontal)

• Total number of pixels in the cluster

• Total number of relevant pixels in the cluster

• ASTM name of the cluster (located in the drop down menu)

• Specific ID to identify that specific cluster (located in the drop down menu)

10.6.3c Search Cluster Section

This section lets the user search through all the cluster of a single type. The user can search by:

• Minimum horizontal size in pixels

• Minimum vertical size in pixels

• Minimum cluster size in pixels

When the search results are generated on the fly, users should pick which results they would like to see in detail.



10.6.4 Inspect ASTM Map

In the Administrative Options window (Figure 106 on page 96), click on the Show Bad Pixel Map button to show the bad pixel map.

Figure 109: Bad Pixel Map

This map (Figure 109 above) will show all the bad pixels in the bad pixel map. When moving the curser on the map, the ASTM name of the bad pixel will be displayed on the left of the window under the pixel X and Y locations.

10.6.5 Send Bad Pixel Map to Rhythm Review

In the Administrative Options window (Figure 106 on page 96), click on the Send Bad Pixel Map to Review button to send the bad pixel map as an image to Rhythm Review. The parameters for sending the bad pixel map to Rhythm Review are located under the Preference section.



10.7Validation

The validation process makes a set of dark images, a set of air images, and then acquires images with the validation phantom in place.

To do a validation, click on Administrative Options. From the Administrative Options form (Validation tab), enter the appropriate technique information (Source distance, mA, kV and Filter Material). Then click Validate Panel.

Figure 110: Validation Button

Go through the validation following the instruction screens that will appear.

Figure 111: Validation in Progress Screen



10.7 Validation (cont.)

Figure 112: Place Phantom Screen

The phantom should be put directly against the detector with the round portion of the phantom aligned with the center of the active detector area. The phantom housing grid outside of the round portion is also used in the validation, so an equal amount must be usable on either side of the round portion. The GE logo on the phantom should be upright on the detector.

Figure 113: Start Validation Screen

Figure 114: Status Screen



10.7 Validation (cont.)

Figure 115: Validation Summary Form

If the validation is successful, the above form (Figure 115) will appear. If the validation fails, another form will appear, detailing the reason the validation failed.

If the contrast in the phantom images is not sufficient for the software to find the phantom features, problems with validation can occur. The situations that follow can affect the contrast:

• Failure to use the necessary filter

• The source-to-detector distance is not set correctly

• The x-rays are not set correctly, if the operator manually controls the x-rays

• The phantom is put upside down, or not correctly aligned with the center.

• The x-ray settings for the validation are not correct.

If the MTF value for the given panel at desired lp/mm is not near the usual value, then the operator should do the validation procedure again. Make sure the dark image levels are not too high. If validation is done just after high exposures were done, the detector will have some charge on it and the dark images will show this. There are several “scratch” images taken in the validation acquisition to avoid this problem, but sometimes it is not sufficient.



10.8Issue Resolution

10.8.1 Ghosting of an Image

• Ghosting occurs under some conditions following an excessively high exposure to a localized region of the detector. When ghosting occurs, the operator can see a transient artifact or remnant from previous exposure frames. It is recommended to stop the x-rays, if the operator does no interpretations or inspections at that time, to avoid this excessive exposure. This is especially applicable if the x-rays are being controlled manually.

• If ghosting shows in an image during inspection, the operator can acquire several static shots with no source exposure; this should remove the ghosting.



10.9X-ray Controller Interface Overview

10.9.1 ERESCO MF4 Safety Precaution

ERESCO is considered as stand-alone field radiography instruments where a trained and certified operator has to ensure all relevant cardinal rules for X-ray safety are taken. The ERESCO controller, equipped with emergency Stop, X-RAY-ON and X-RAY-OFF buttons, shall always be in the near proximity of the operator. Rhythm RT only sends the relevant technique data the ERESCO and provides synchronization with the DXR acquisition. Activation of X-ray can be only done via the ERESCO controller.

Please consult the ERESCO operation manual for all relevant equipment safety and operational instructions.

Due to ERESCO MF4 safety requirements, the user will be prompted to start X-rays manually when this controller is selected in “Preferences”. The following dialog is displayed whenever the Eresco MF4 X-ray unit is started from the Rhythm RT Acquisition interface.

Figure 116: Startup Dialog

At this point, the user must click the OK button on the dialog for Rhythm to confirm that all cardinal safety rules of field radiography have been considered and the user will be required to press the X-RAY-ON button on the controller panel in order to energize the X-ray unit.

IMPORTANT: Whenever the ERESCO is ready for operation, the X-RAY ON button on the ERESCO controller is illuminated.



10.9.2 Configuration

To configure ERESCO communication settings, click on the toolbox icon in the X Ray Central pane.

AdministratorOptions



10.9.2a ERESCO Communication

Figure 118: Communication Settings

Make sure that the communication settings on the ERESCO as well as on the host PC side are corresponding. A connectivity test can be executed by clicking Test Connection.



10.9.3 Administrative Options

To activate the X-ray control, click Link to Xray controller on the General tab of the Administrative Options menu.

Figure 119: General Tab with X-ray Control Options

In order to use the exposure settings from the components database, click Overwrite General DR exposure with the current technique settings. Otherwise the exposure settings from the “Static Acquisition” mode will be taken. They are different ways to enter exposure times, depending on the configuration

Figure 120: Static Acquisition and Current Technique Settings



10.9.4 Exposure Time

The ERESCO MF4 controller exposure time can only be set by a precision of 1/10 of a minute. As such, when the Eresco controller is selected from the Preferences dialog, the Exposure (s) entry field will change to a NumericUpDown object, which will only allow the user to enter time in six second intervals.

Figure 121: Exposure Settings in Technique

In the event the user attempts to enter some exposure time which is not evenly divisible by six, a dialog prompting the user to enter a valid exposure time will appear, and no changes will be saved until the user complies.

Figure 122: Preselection Time Six-Second Multiple Dialog



10.9.5 Acquiring an Image (Synchronized Acquisition with Eresco MF4 and Portable DXR Detectors)

Depending on the selected configuration, a DXR acquisition can be executed based on technique information taken from the components database or DXR technique data from the Static Acquisition window. Just as with Technique entry, while the Eresco MF4 controller is selected in Preferences, the Exposure Time (s) will only accept 1/10 of a minute entries as valid.

Figure 123: Exposure Time

Click on the Acquire button to start the Acquisition. An invalid entry will cause the same error dialog seen when entering an invalid exposure time to appear, and the Static Acquisition will abort.

Due to the ERESCO MF4 safety requirement, after clicking Acquire, the user will be prompted to start the X-rays manually from the controller.

Figure 124: Safety Dialog

The user must click OK on the safety dialog to confirm that all safety measures are taken and must then press X-RAY-ON at the ERESCO to start X-ray and proceed with the acquisition.

IMPORTANT: The Image Acquisition will be synchronized with the ERESCO exposure. In order to cover X-ray ramp up time / X-ray shut-down time the actual X-RAY ON time will be approximately 24 seconds longer than the selected exposure time for the image acquisition. Hence, a total of 24 seconds will be added to DXR exposure time. Once the image acquisition is completed, the X-ray operation will be switched off by Rhythm RT.

In addition, the pre-set ERESCO exposure timer will make sure that the exposure will be terminated once the counter expires.



10.9.6 Service Mode

Figure 125: Service Mode Option

The Service Mode prevents Acquire from controlling the starting of X-Ray equipment, even if an X-Ray controller is selected. This needs to be enabled as a safety measure in the case someone is troubleshooting a system remotely. Upon enabling Service Mode, the user is notified of the implications of this option.

Figure 126: Control Disabling Warning

In a similar fashion, when starting Acquire and an X-Ray controller is selected, the user will be notified that automated X-Ray control is enabled.

Figure 127: X-Ray Enabling Warning

This notification is also displayed when the user first enables an X-Ray controller in the Preferences dialog.



10.9.7 Automatic Calibration File Upgrade

Calibration files created with Acquire prior to release 4.1.31.0 follow a different naming convention. Upon starting, Acquire scans the directory for files which use the old naming convention. If they are detected, they are automatically renamed and placed in the new directory structure. As a safety precaution, the files are also copied to the directory Rhythm_RT\Pre Cal File Upgrade.

10.9.8 Study and Instance Level Tags

Study Level Tags (Generic Study 1, etc.) provide the user the opportunity to annotate component acquisitions with text data that provide descriptions about the subject of the acquisition. Instance Level Tags (Generic Field 1, etc.) provide the user the opportunity to annotate technique acquisitions with text data that provide descriptions about the technique used for the acquisition.

Figure 128: Study and Instance Level Tags

The user has up to 10 study and instance tags each. If the user does not wish to use all of the tags, it is possible to hide tags from view.



10.9.8 Study and Instance Level Tags (cont.)

2. Click the Bad Pixel Map button and follow the existing calibration process to generate a bad pixel map.


Figure 170: Binning Mode Calibration Settings



10.10.4Basic Image Acquisitions

There are two basic image acquisition modes, Static and Real-time.

For each image acquisition mode, calibration files (Pixel map, Gain and Offset maps) generated from Step 3 can be applied to it during image acquisition. There is currently only one default Gain for this detector, which is 4400 e/ct. The resolution for basic image acquisition is 200 micron, although resolution can be changed to 400 micron when it is used in Binning mode in Advance image acquisition. For Static mode, the image exposure time is set between 200 milliseconds to 120 seconds. For Real-time mode, the number of frames per second is set between 0.2 to 5 frames. These values will be changed when Binning mode is used (See Section 5).

10.10.4aStatic Image Acquisition

1. Select Static from the DXR Mode listbox (Figure 171).

2. Enter the number of frames to be averaged.

3. Enter the exposure time for each frame.

Figure 171: Static Data Acquisition



10.10.4b Real-time Image Acquisition

1. Select Real-time from the DXR Mode listbox Figure 172).

2. Enter the number of frames per second.

Figure 172: Real-time Image Acquisition

10.10.5Advance Image Acquisition and Detector Settings

Advance image acquisition and detector settings can be accessed from the Administrative Options -> 250C-W Settings tab page. These settings are grouped into three categories and each category has specific defined settings.

10.10.5aAcquisition Settings

Image acquisition settings are listed under the Acquisition Settings group on 250C-W Settings tab page on the Administrative Options form (Figure 173 on page 138).

• EMI Correction - This setting is to turn On/Off EMI correction on acquired images. When EMI is turned on, you can also specify three EMI related parameters or use their default values. These three EMI related parameters are:

• Amplitude Threshold - RT attempts to remove all noise signals with amplitude above the specific threshold.

• Frequency LSL - RT attempts to remove all noise signals with frequency greater than specific lower level frequency threshold.

• Frequency USL - RT attempts to remove all noise signals with frequency less than specific upper level frequency threshold.

• ROI - Detector only reads out center portion(512x512) of acquired image and sends the image data to host when ROI is set to On.

• Binning - Detector sums up every two rows and two columns as single row and column. As a result, it sends out 512x512 image data to host when Binning is set. Note that the pixel count of Binning mode is about twice as much as normal mode.



10.10.5a Acquisition Settings (cont.)

• Accumulate Frames - This option allows you to accumulate multiple frame pixel values into one single frame pixel values. The final frame pixel values are saturated at 16383. The default value is set to 0 which turns this option off.

Figure 173: Acquisition Settings

10.10.5bDetector Settings

Detector settings are under Detector Settings group on 250C-W Settings tab page on the Administrative Options form (Figure 174 on page 139).

• Synchronize Pulse Source - When it is set, detector and host will use synchronous communication during image acquisition. The sequences of synchronous communication are:

a. Host requests detector to start image acquisition.

b. Detector acknowledges it and replies back to host that it is ready for x-ray exposure.

c. Host receives the detector reply and notifies users to start x-ray with a message box.

d. When exposure is complete, the user closes the message box and the host then notifies the detector that x-ray exposure is completed.

e. Detector acknowledges the exposure completed notification, reads out image and sends the image data to host.

• No Activity Timeout - It is used to set the detector's no-activity-timeout property. When the specific timeout is elapsed, the detector will shut down itself if it is powered by a battery. The default value is set to 3600 seconds, the valid values are between 0 -7200 seconds.

• Active Power Saving mode - When this option is set, panel will go to Power Save mode (Figure 175 on page 139) to save battery power every time when it finishes image acquisition after DXR Viewer window is closed. Note that if detector is not powered by battery, this option is ignored and detector is always in full power mode. If the detector is in power save mode when user starts an image acquisition, the detector will be automatically brought up to full power and it will takes about 15-20 seconds for detector to go from power save mode to full power mode. The user will be notified by displaying the status in DXR Viewer title bar during this power transient period.



10.10.5b Detector Settings (cont.)

Figure 174: Detector Settings

Figure 175: Power Save Mode



10.10.5cDetector Tools

Detector Tools are under the Detector Tools group on 250C-W Settings tab page on the Administrative Options form (Figure 176). All the tools under the group are disabled if there is no detector connected to the host at the time except the View Log button. These buttons will be enabled when a detector is connected to the host.

• Disable Wireless - This is used to disable wireless inside the detector. After detector wireless is disabled, detector cannot connect to host using Wi-Fi AP/Ad hoc mode. If detector wireless is already disabled, then this button is disabled

• Enable AP/Ad hoc - This is used to toggle detector Wi-Fi setting between access point mod or Ad-hoc mode

• Detector Signature - It queries detector signature and displays the content of detector signature

• Voltage Test - This is used to run voltage sensors test in detector and display all the voltage sensors results when test is done

• BIST Test - This is used to run detector build-in-self test and display the test result when it is completed

• View Log - View all entries logged by Rhythm RT. The log file will be archived as old log file when it reaches 100 MB in file size or an error occurred in xml syntax in the log file, then a new log file will be created

Figure 176: Detector Tools



10.10.6Resume Image Acquisition

In order to acquire all requested frames after image acquisition started, the 250C-W module implements a mechanism that automatically resumes image acquisition due to interruptions such as detector internal buffer empty, network connection dropped/reconnected or changing battery during the course of image acquisition.

10.10.6aResume on Detector Internal Buffer Empty

When image transmission speed between host and detector can't keep up with the detector acquisition speed, such as 10 frames per second for Binning mode, the detector will stop acquiring image when its internal buffer is empty. When this happens, the 250C-W module automatically sends a restart command to the detector to restart the image acquisition without user interaction (Figure 177) if the image acquisition was not completed at the moment.

Figure 177: Resuming Acquisition

10.10.6bResume on Network Connection Dropped

When image acquisition is interrupted due to a network connection being dropped, such as no wireless signal in range or changing battery, the 250C-W module will notify users that connection is dropped and offer that they retry (Figure 178) when connection is back in range/battery is plugged in again.

Figure 178: Dropped Connection



10.10.7Network Troubleshooting Tools

In case of seeing a connection issue between Detector and Host, a context menu tool is available in the upper left corner of the 250C-W user interface (Figure 179).

• Ping Detector - This tool is used to check the connection between detector and host

• Ping Access - this Point tool is used to check the connection between Access Point and host

• Network Connection - This tool is used to open the window network connections dialog

• Restart Service - This tool is used to restart the background service process which initiates connection to detector and monitors detector status such as detector temperature, wireless strength and remaining battery power

Figure 179: Troubleshooting Tools

10.10.8Query and Manage Detector Tools

There are some handy detector tools in the context menu tool from the upper left corner of 250C-W user interface for easy access. Note that these tools are only available when host is connected to detector (Figure 180).

• Detector Signature - This tool is used to query the detector signature. You can get the detector signature from Administrative Options->250C-W Settings -> Panel Signature.

• Wireless Status - This tool is used to query the current wireless setting in the detector.

• Power Save Mode - This tool is used to bring the detector to Power Save mode. Note that it is only available when the detector is powered by battery (Figure 175)

• Reboot Detector - This tool is used to reboot the detector.

• Shutdown Detector - This tool is used to shut down the detector.

11.1 Send Images

This section describes how Rhythm RT manages images received from a scan device.

Images are received at Rhythm RT through the Scan process. Once the image is received, it will appear in the Image Queue. The Image Queue area is where images are managed once received at Rhythm RT.

To send an image, click on the image in the queue and click on the Send Image button.

If Auto Send is enabled, then the images will appear in the queue and be automatically sent to the Review station. If Auto Delete is enabled, then the image will be removed once sent to the Review station.

Figure 181: Send Image Button

Note: This process might take place quickly, so that the appearance of the image in the queue is not noticeable.

If Auto Delete is not enabled, the image will stay in the queue after it is sent, though the extension of the image will change from .raw to .snt to indicate the image has indeed been sent to the Review station. The image can be manually deleted once verified at the Review station.

11.1.1 Study ID

The Study-ID is the identifier that is associated with your specific part. The Component ID is the “part type” identifier, where this ID is the actual Serial # or other identifier on the part that uniquely identifies it.

11.1.2 Local Studies View

With the Study-ID each image is put into the same study as a series. If this part is then sent back for rework and is shot again with View A, B & C, a new series will appear beneath this same Study.



11.1.3 Send / View Image

Figure 182: Local Components View

Figure 183: Component ID

For greater image management in Local Components View, the Component ID is the main identifier; within Component ID will be found the studies by Study-ID, then within Study-ID the series of images by technique.

11.1.4 Image Comments

The area allows comments to be added along with the image being sent to the Review station.



11.1.5 Enable Auto Send

This feature allows the scanned image to go directly to the Review station or stay in the image queue until manually sent. Click on the Enable Auto Send checkbox.

Figure 184: Enable Auto Send Checkbox

The following message will appear

Figure 185: Message Box

Click Yes to enable.

When the image is acquired, it will automatically be sent to the Review station selected in System Configuration, with the currently selected technique information associated.

Note: The correct technique must be selected prior to scanning when Auto Send is enabled. If Auto Delete (see “Enable Auto Delete” on the next page) is disabled, then the image will still appear in the queue with a .snd extension, else it will be deleted automatically.



11.1.6 Enable Auto Delete

This feature allows the sent image to be automatically deleted once it is sent.

1. Click on the Auto Delete checkbox.

Figure 186: Auto-Delete Checkbox

The following message will appear:

Figure 187: Auto-Delete Message Box

2. Select Yes to enable. When the image is sent (either manually or automatically), the image file will be deleted from the acquisition temp location.

Note: Once the image is deleted, it cannot be re-sent. If for some reason your network is not behaving properly and you are concerned your images are not reaching the Review station, you would want to leave the Auto Delete feature disabled to verify that the image has been received before deleting from the acquisition station.



11.1.7 Manual Delete

The image can be deleted from the queue manually, by selecting the image node or its parent node in the tree on the View Images form. Click on the Delete button on the bottom of the form.

Acquisition Process

The acquisition process is a sequence of procedural steps that has as its result one or more radiographic images.

Active

A currently selected form (window) or icon noted by a change in color of title or label. A window or icon must be active to register commands and keystrokes. An active window sits on top of multiple windows.

Air Image

The radiographic image that is the result when the system reads the detector with the x-rays on and no inspection object in the beam.

Application

A computer program used for a particular job, such as word processing or database management. Sometimes called application program.

Application Icon

A small graphic that represents a running application.

Application Window

The window containing the work area and menu bar for an application. The name of the application appears at the top of this window. An application window may contain multiple document windows (forms).

Arrow Keys

Located on keyboard, these keys are used to move cursor or objects around the screen. They are also known as direction keys.

Beam

The cone-shaped radiation field emitted from the x-ray tube.

Bit

A bit is a single unit of binary information. In a computer, a series of bits represents integers. The number of bits used limits the resolution and range of integers that can be represented. For example, the 14-bit numbers used in the DXR System detector supply 16,384 levels of digitization.



Browse

To look through files and directories. Some dialog boxes have Browse buttons, which open another dialog box that lists files and directories so that you can easily select the file you want.

Calibrate

A function that increases accuracy by determining the deviation from an assigned standard to ascertain the proper correction factors.

Calibration Procedure

Validation Procedure

Validation is the procedure that measures the performance of the system. The operator uses a known phantom object to do a validation. The validation lets the operator assess and monitor the system performance over time. An analysis of acquired images is done to produce image quality metrics including electronic noise, uniformity, brightness, noise power spectrum, spatial modulation transfer function (MTF), contrast, dynamic range linearity and a measure of detector quantum efficiency (DQE).

Viewing Parameters

The detector measures the amount of x-ray energy at each active element. These measured values are mapped onto a range of gray intensities to form an image. The range of measured x-ray values is usually much larger than the number of grays that can be distinguished by the human eye. Thus, only a portion of possible measurement values is displayed. Image viewing parameters define the contrast and brightness. They are specified as a window and a level of the image pixel values.



Window

The window is range of the gray scale map. The window is typically selected to make visible a range of counts that the user is interested in viewing on a monitor. In many regards, it is equivalent to setting the contrast of the display. The adjustment is usually combined with a level adjustment.
