CAR '97 DICOM Demonstration CD



The DICOM (Digital Imaging and Communications in Medicine) standard is a detailed specification that describes a means of formatting and exchanging medical images and associated information. DICOM was approved by ACR-NEMA in November 1993 and by CEN/TC251 as a European Standard in 1995 (ENV 12052:1995 - MEDICOM). DICOM relies on computer industry standard network connections such as TCP/IP and on offline media such as CD-R. DICOM supports a range of diagnostic modalities beyond CT and MR, including Nuclear Medicine, Ultrasound, Computed Radiography, X-Ray Angiography, X-Ray Radiofluoroscopy, digitized film and video capture. DICOM also includes mechanisms for accessing image archives, the integration of imaging equipment with other information systems and the connection of networked hard-copy devices.

DICOM General Purpose CD-R Image Interchange Profile

In order to exchange images using offline media it is necessary to select from a variety of possible choices including physical media type, filesystem format and data encoding. DICOM Supplement 19 defines such an "Application Profile" which is appropriate for general purpose interchange of multi-modality images and related data using CD-R media. This profile permits any type of image to be included but allows only a single specific encoding of uncompressed images (using the "Explicit VR Little Endian Uncompressed Transfer Syntax"). DICOM also defines other application profiles for specific clinical contexts where alternative choices are more appropriate.
