A.89.3.1 Photoacoustic Image IOD Content Constraints

A.89.3.1.1 Modality

The value of Modality (0008,0060) shall be PA.

A.89.3.1.2 Photometric Interpretation and Pixel Presentation

If Pixel Presentation (0008,9205) in the Photoacoustic Image Module equals COLOR or MONOCHROME, the Photometric Interpretation (0028,0004) shall be MONOCHROME2.

If Pixel Presentation (0008,9205) in the Photoacoustic Image Module equals TRUE_COLOR, the 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. See Table C.8.34.1.3-1 for combinations of parameter values.

Note

Future lossless and lossy Transfer Syntaxes may lead to the need for new definitions and choices for Photometric Interpretation.

A.89.3.1.3 ICC Profile Module

The ICC Profile Module shall be present if Pixel Presentation (0008,9205) in the Photoacoustic Image equals TRUE_COLOR or COLOR. If the color space to be used is not calibrated (i.e., a device-specific ICC Input Profile is not available), then an ICC Input Profile specifying a well-known space (such as sRGB) may be specified.

A.89.3.1.4 Ultrasound Frame of Reference

The Ultrasound Frame of Reference Module is mandatory for Photoacoustic even in cases where Ultrasound is not used as a complementary modality due to the use of the Image Position (Volume) (0020,9301) in the Photoacoustic Dimension Index.

A.89.3.1.5 Real World Value Mapping

If the Real World Value Mapping Sequence (0040,9096) is present, it shall not be inconsistent with the Image Data Type Sequence (0018,9807).
