Mission and goal of DICOM
ITU-T
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

Some recent new developments
ITU-T
o 16 parts of official DICOM 2003 edition
available at: http://medical.nema.org
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

Some recent new developments
ITU-T
23-25 May 2003
o New Media
• DVD-R, E-mail attachments, large
capacity MODs
o New Objects
• Multi-frame MR

Multi-frame MR
ITU-T
o New object definition supporting latest
advancements in MR technology
o Support for very large data sets, split of
an acquisition between several multiframe objects
o New concepts – functional groups

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

DICOM Object Access via Net
ITU-T
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

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.

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.

“Electronic Health Record”
ITU-T
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

“Electronic Health Record”
ITU-T
23-25 May 2003
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

Summary
ITU-T
o DICOM is well positioned to continue to
serve integration needs of medical
imaging, including workflow, evidence
information recording, effective access
to imaging results in the enterprise
o Active cooperation with other standards
assures DICOM objects integration into
future EHR – whether by reference, or
through well-defined trans-coding
mechanisms.
