AIMDICOM file management system to transfer Medical Images securely. In DICOM format, these records can then be sent to the DICOM server so that they may be accessed via the DICOM Viewer for Diagnosis by Doctor whenever it is necessary.To build an easy and efficient Common DICOM conformance model for transmission, receiving and storing of medical images.

Existing DifficultiesIn the past, many of the medical information produced by hospitals (such as medical records or imagery) have trouble to transfer from place to place.The main reason for this being the difference in the many formats that are used by each and every brand. At present there are number of methods available for the communication and storage of DICOM images. Medical equipment manufactures choose those that are favourable to them. Till now there are no common standards for these image communication methods.

Challenges in current scenarioWith the introduction of computed tomography (CT) followed by other digital diagnostic imaging modalities and the increasing use of computers in clinical applications, there is an emerging need for a standard method for transferring images and associated information between devices manufactured by various vendors. These devices produce a variety of digital image formats .Difficulties may be ,we can not make any communication of digital image information in Medical Imaging fieldWe can not make interface with other systems of hospital information or Radiology Information system easily

PROPOSED SYSTEMThis System reports the simulation result of integrating several systems to cope with (HIS,RIS,PACs) limitations by using the DICOM standard.This System will be designed mainly to efficiently receive all images from any new DICOM Compliance Machines or Modalities using DICOM Conformance Common Model.

Continue..The received Images will be properly Archived using Archive Management and the Archived Information will be viewed by the in-built DICOM Viewer for Diagnostic purpose by Doctor for Analyzing the Images..This System proposed the common DICOM conformances model.This DICOM conformance common model will choose the efficent one among the various options in existing DICOM protocols.

Main FunctionalitiesProvide the capability to receive DICOM 3.0 images from any DICOM 3.0 compatible modality. Storing this clinical information in a secure environmentDistributing and displaying both clinical images and corresponding diagnostic information to Doctors throughout a hospital or clinic using Medical Imaging TechniquesSystem should support unlimited DICOM Compliance modalities.- Common Interface

Advanced concepts Involved in this Project

Embedded System Concepts and Understanding of RTOS Communication between Embedded System to PC Based SystemAdvanced level understanding of DICOM (DICOM in Network- Using DICOM PROTOCOL)Advanced Medical Imaging Concepts and its implementationImage conversion techniques ( Non DICOM to DICOM)Implementing Medical Imaging / Health care Standards HIPAA , HL7 Web Enabled Medical Imaging Communication systemComponent Object Model (COM) architecture and its implementationIntegration of HIS,RIS and PACS

DICOM RECEIVE AND ARCHIEVE MANAGEMENT

Scope :This Module has to receive DICOM output from Different DICOM Compliance ModalitiesAt first , receiving DICOM Data from one Modality is the scope of this Present ModuleFuture Scope :Then ,it will be generalized to N (20 or More) number of any DICOM Compliance Modalities- It will become focusing unique feature ,Once it is doneNeed to give solution for NON DICOM Data from Modalities so that NON DICOM Data will be converted into DICOM data by adding Additional Software and HardwareRISKS : In reality , receiving DICOM Data depends on Modalitys manual. Advanced TCP/IP networking and DICOM Protocol in Network concept will heavily be used to receive DICOM Data from Modalities.

BENEFIT OF This SystemThe biggest benefit derived from this system is breaking the physical as well as time barrier for information exchange. The film librarians job shrinks to providing copies and reprints for clinicians etc. . who are outside the hospital network Radiologists are going to be happier since comparative exams are always available The efficacy of clinicians is possible if all the information they need is available at one place.
