  3. 3. ITU-T Mission and goal of DICOM o Mission of DICOM • Create and maintain international standards for communication of bio-medical diagnostic and therapeutic information o Goals of DICOM • Achieve interoperability and improve workflow efficiency between imaging systems and other information systems
  4. 4. ITU-T Some recent new developments o 16 parts of official DICOM 2003 edition available at: o Security • De-identification, Clinical Trials o Applications of structured reporting (DICOM SR) – Evidence documents: • Chest CAD • Cath Lab Reporting • OB-GYN, Vascular US, Echocardiography
  5. 5. ITU-T Some recent new developments o New Media • DVD-R, E-mail attachments, large capacity MODs o New Objects • Multi-frame MR • New CT, XA, VL o JPEG 2000 o Configuration Management
  6. 6. ITU-T Multi-frame MR o New object definition supporting latest advancements in MR technology o Support for very large data sets, split of an acquisition between several multi- frame objects o New concepts – functional groups
  7. 7. ITU-T Ultrasound Procedure Reporting o A number of supplements covering different areas of US procedure reporting: • OB-GYN • Vascular • Echocardiography o Further advances the concept of Evidence Documents – objects generated by machine, that are not images but are carrying the supplemental coded information for the procedure to aid in diagnosis
  8. 8. ITU-T DICOM Object Access via Net o In addition to the e-mail distribution of DICOM objects, DICOM recently spearheaded a joint Work Item with ISO TC215 – WADO Web Access to DICOM Persistent Objects • In currently prototype phase • Will allow for web-access to images in different formats utilizing standardized URL (HTTP-GET) • In conjunction with standardized MIME type allows for access using a Web Browser
  9. 9. ITU-T Charter of Strategic Advisory Committee o To develop and maintain the long-term strategic plan of the DICOM Standards Committee; o To review standards and technology trends in healthcare, biomedical imaging, commerce, telecommunications, and informatics; o To consider issues and opportunities related to the strategic evolution of DICOM; o To provide liaison to other standards developing organizations: ISO, HL7, JIRA, CEN.
  10. 10. ITU-T Quality of care improved by information and IT All relevant information the care giver and patient need, anywhere and anytime, for the best clinical decisions, through one common and simple user interface, adapted for the task.

  26. 26. ITU-T “Electronic Health Record” o Image Management system and Departmental Information Systems must be EHR-prepared (Query/Retrieve) o EHR: emphasis today on visual integration on the desktop, will become the integrated, secure, patient centric, source of health information o Need for coded vocabularies to represent medical knowledge and the patient’s health condition
  27. 27. ITU-T “Electronic Health Record” o Web front-end: • viewing not only of images but also waveforms, measurements, reports, lab results, etc • need the capability to access the original medical images • Support for (DICOM) Structured Reporting • XML and XML Schema for the exchange of clinical documents
