A.36.4.3.1 Enhanced MR Color Image IOD Content Constraints​

The General Image Module, Overlay Plane Module and VOI LUT Module shall not be used in a Standard Extended SOP Class of​ the Enhanced MR Color Image.​

Note​

In order to annotate images, whether during acquisition or subsequently, SOP Instances of the Color Softcopy Presentation​ State Storage or the Structured Report Storage SOP Classes that reference the image SOP Instance, may be used.​

NostandardmechanismisprovidedforinclusionofannotationswithintheimageSOPInstanceitself,andimplementersarediscouraged​ from using private extensions to circumvent this restriction.​

Color Softcopy Presentation State Storage Instances that are generated during acquisition may be referenced from the Image SOP​ Instance by using the Referenced Presentation State Sequence in the MR Image and Spectroscopy Instance Macro invoked from​ the Enhanced MR Image Module. See Section C.8.13.2.​

Photometric Interpretation (0028,0004) shall be RGB for uncompressed or lossless compressed Transfer Syntaxes that do not have​ defined color space transformations, YBR_ICT for irreversible JPEG2000 Transfer Syntaxes, YBR_RCT for reversible JPEG2000​ Transfer Syntaxes, YBR_PARTIAL_420 for MPEG2, MPEG-4 AVC/H.264, HEVC/H.265 Transfer Syntaxes and YBR_FULL_422 for​ JPEG lossy compressed Transfer Syntaxes and YBR_FULL or RGB for RLE Transfer Syntaxes.​

Note​

Future lossless and lossy Transfer Syntaxes may lead to the need for new definitions and choices for Photometric Interpret-​ ation.​

Pixel Presentation (0008,9205) shall be TRUE_COLOR.​
