Note: The modality attribute (0008,0060) in the DICOMDIR Series records should be CT/MR
for Secondary Capture and Standalone Overlay SOP Class Images. Otherwise the
LightSpeed DICOM media display browser will not list-up the series for contents
rendering the retrieval to local storage impossible.
3.4.4.1.4.1 Additional Keys
None.
3.4.4.1.5 Other Parameters
This section defines other parameters common to all specific Application Profiles in the PRI-
CTMR-MOD12 class that need to be specified in order to ensure interoperable information
interchange.
See 3.4.2 for JPEG encoding problem in the PRI-CTMR-MOD12 profile.
3.4.4.1.5.1 Image Attribute Values
The attributes listed in Table 3.3.3.1.5.1-1 used within the CT/MR/SC/Standalone Overlay
Image files, shall take the values specified.
Overlay data if present shall be encoded in Overlay Data (60XX,3000).
3.4.4.1.5.2 Attribute Value Precedence
None.
3.5 Extensions, Specializations and Privatization of SOP Classes and Transfer Syntax
3.5.1 Extensions, Specialization’s and Privatization’s of SOP Classes
The CT/MR SOP Class Images have definitions extended for Defined Terms and include GE
specific Private Data elements. The following sections describe the details for these SOP
classes.
3.5.1.1 SOP Specific Conformance Statement for CT SOP Class
Refer to section 2.5 for standard extensions and Appendix B for private data elements.
3.5.1.2 SOP Specific Conformance Statement for MR SOP Class
Refer to section 2.5 for standard extensions and Appendix B for private data elements.
3.5.2 Private Transfer Syntax Specification
The SOP instance files in the Media File-set in the PRI-CTMR-MOD12 profile uses a non-
standard JPEG compression process resulting in interoperability problems when decoded using
readily available industry standard JPEG decompression routines.
