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

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

“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.
