A.32.4.2 VL Photographic Image IOD Entity-Relationship Model

A.32.4.2 VL Photographic Image IOD Entity-Relationship Model
Prev	A.32.4 VL Photographic Image IOD	Next

The E-R Model in Section A.1.2 depicts those components of the DICOM Information Model that directly reference the VL Photographic Image IOD, with exception of the VOI LUT, Frame of Reference and Modality LUT entities, which are not used. Additionally, Image in Figure A.1-1 represents a single-frame image. A frame denotes a two-dimensional organization of pixels recorded as a single exposure. Table A.32.4-1 specifies the Modules of the VL Photographic Image IOD.

Note

The Curve entity was previously include in the list of entities that are not used, but has been retired from DICOM. It is still not used in this IOD. See PS3.3-2004.
The Specimen Identification Module was previously included in this IOD but has been retired, and its functionality replaced by the Specimen Module. See PS3.3-2008.
