August 1, 2005

The DICOM standard is changing with the times to include a new family of CT and MR objects.

The DICOM standard is changing with the times to include a new family of CT and MR objects.

SCAR, the National Electrical Manufacturer's Association, and DICOM are working with vendors to provide tools and an infrastructure for developing, testing, validating, and demonstrating new objects designed to support the rapidly advancing capabilities of CT and MR technologies.

Those test tools and sample images, along with open source code not yet publicly accessible, were expected to become available after the 2005 SCAR meeting.

The original DICOM CT object contained 18 attributes, none of them mandatory for vendors, and four terms, two of which were enumerated-meaning all vendors must comply. The enhanced CT object has 41 attributes, 39 of them mandatory, and 86 terms, 18 of them enumerated.

The original object for MR defined 44 attributes, only two of them mandatory, and 38 terms, nine of which were enumerated. The enhanced DICOM MR object includes 103 attributes, 94 of them mandatory, and 228 terms, 47 enumerated.
