Points of InterestPoints of Interest

Appendix E, Volume 1 (Informative)– New to Nuclear Medicine?– Trouble matching NM to Scheduled Workflow?

– E.2 NM Workflow – What happens in NM procedures– E.3 NM Worklists – How to schedule/model it– E.4 NM Data – What to expect in the DICOM– E.5 NM Display – How it should be presented

– Lots of subtleties

HIMSS/RSNA Participant Workshop, Oct 2004

Points of InterestPoints of Interest

Acquisition Modality – Modality Images Stored [8]– Create NM objects as specified

additional attribute & vector handling– e.g. Cardiac context codes, slice spacing, patient

orientation Study & Series UID creation clarification

– e.g. After PPS complete, new images MUST be new series– e.g. Reconstructed images MUST be new series

Points of InterestPoints of Interest

Image Manager/Archive– Store/Retrieve NM Objects– Store/Retrieve Secondary Capture Objects

Refer to list in the spec.

– “Level 2” storage requirement clarification e.g. keep private tags

– Support for Series Description as Query matching/return key

Render Static and Dynamic Result Screens– Based on the following DICOM Objects:

Secondary Capture Multi-Frame Grayscale Byte Secondary Capture Multi-Frame True Color Secondary Capture

– Generate appropriate Secondary Capture objects from any Result Screens created.

Points of Interest – Image DisplayPoints of Interest – Image Display

Image Display– Retrieve Images [16]– Display NM and Secondary Capture Images

Note requirement for Color, Greyscale, Static & Dynamic Secondary Capture

– Support specified NM essential display capabilities

– Additional attribute handling e.g. Patient State, Image Orientation, Detector

Sequence, View Code Sequence

– Review Option

HIMSS/RSNA Participant Workshop, Oct 2004

Handle multi-frame / multi-vector images Multiple simultaneous cines Grayscale and color result screens Dynamic and static result screens Original resolution and scaled

Separate adjustment of upper and lower window levels Apply local color tables to grayscale screens Add color tables to system Change intensity of grayscale result screens

– (strongly recommended) Display Series Description tag

Scale “intelligently” to avoid presenting postage-stamp size NM images– Just because it was acquired at 64x64

doesn’t mean they want to review it at 64x64

HIMSS/RSNA Participant Workshop, Oct 2004

Points of Interest – Image DisplayPoints of Interest – Image Display

Scale “intelligently” to avoid presenting postage-stamp size NM images

Allow user to select different vectors/framesets of complex multi-frame images

Allow user to separately adjust intensity for different framesets (eg, phases) in the same “image”

Review OptionReview Option

<More details>

Adds requirements to the Image Display to allow Review of NM Images

Image Displays– Must additionally support MPR Display,

more series, selected different series types together, etc.
