A.8.5.4 Multi-frame True Color SC Image IOD Content Constraints​

The VOI LUT Module shall not be present.​

In the Image Pixel Module, the following constraints apply:​

•​Samples per Pixel (0028,0002) shall be 3​

•​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 JPEG 2000 Transfer Syntaxes, YBR_RCT for reversible JPEG​ 2000TransferSyntaxes,YBR_PARTIAL_420forMPEG2,MPEG-4AVC/H.264,HEVC/H.265TransferSyntaxesandYBR_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 Inter-​ pretation.​

A.14 X-Ray Angiographic Image IOD​

A.14.1 XA Image IOD Description​

ThisSectiondefinestheInformationObjectforsingleplaneX-RayAngiographicImagingthatincludesthoseAttributesandInformation​ Objects necessary for the interchange of digital X-Ray Angiographic data. This includes images of the heart and all blood vessels.​

The XA IOD share a significant amount of common information with the XRF IOD. The differences between the two IODs are that​ the XRF Image IOD includes a tomography Module; and the two IODs utilize different methods to specify positioner angles. The XRF​ Image IOD contains a single column angulation Data Element that uses an Equipment-Based Coordinate System, while XA Image​ IOD c-arm positioner angles are specified in a Patient-Based Coordinate System. RF applications that support a Patient-Based Co-​ ordinate System with cranial/caudal, LAO/RAO angles may utilize the XA IOD.​

The XA IOD is also applicable to clinical areas other than angiography (e.g., Interventional Procedures, Myelography, Biopsy/Local-​ ization, and Neurology).​

2.​A typical Study might include all the images generated between the time a Patient gets on and gets off the procedure​ table. As several separable diagnostic or therapeutic processes may occur during a single Study (e.g., pre-intervention​ CA, left ventriculography, and post-intervention CA), a Series may be defined as comprising a set of images (single or​ multi-frame) associated with one such process within a Study.​

3.​This IOD can be used to encode a single plane acquisition, or one plane of a biplane acquisition.​

A.16 X-Ray Radiofluoroscopic Image IOD​

A.16.1 XRF Image IOD Description​

The focus for this X-Ray Radiofluoroscopic IOD is to address the requirements for image transfer found in general Radiofluoroscopic​ applications performed on a table with a column. For applications performed on X-Ray RF acquisition systems that support a Patient-​ Based Coordinate System with cranial/caudal, LAO/RAO angles, etc. the XA Image IOD may be used.​

Note​

An example of a case where the XA IOD may be preferred to the RF IOD are RF acquisition system equipped with an X-​ Ray source and an image Receptor positioned by what is generally called a c-arm (e.g., Interventional Procedures, Myelo-​ graphy, Biopsy, and Neurology).​

ThisSectiondefinestheInformationObjectforX-RayRadiofluoroscopicImagingthatincludesthoseAttributesandInformationObjects​ necessary for the interchange of digital X-Ray RF Image data. The XRF IOD is applicable to X-Ray acquisition systems equipped​ with an image receptor whose plane is parallel to the table plane where the Patient is. This Table has in general the ability to be tilted.​ Furthermore the X-Ray source may be supported by a column that can be angulated to adjust the incidence of the X-Ray beam on​ the image receptor plan. An equipment based coordinated system is used to track these angles.​

Note​

2.​A typical Study might include all the images generated between the time a Patient gets on and gets off the procedure​ table. As several separable diagnostic or therapeutic processes may occur during a single Study, a Series may be​ defined as comprising a set of images (single or multi-frame) associated with one such process within a Study.​

A.16.2 X-Ray Radiofluoroscopic Image IOD Entity-Relationship Model​

This IOD uses the E-R Model in Section A.1.2, with only the Image IE below the Series IE.​

Note​

WhenaStudy(orStudyComponent)containsanumberofMulti-frameimagesthatdonotneedtobegroupedunderdifferent​ Series, a single Series may be used with a Series number containing an arbitrary value (e.g., 1).​
