Note

The Overlay Plane requirement is determined by the presence of "graphic annotation". Graphic annotation includes user or machine drawn graphics or text (such as computer assisted diagnosis) to indicate regions of interest or descriptions. It specifically does not include Patient or image identification or technique information that is defined in other Attributes of the IOD.
The Device Module and Intervention Module are User optional, though it is desirable that, if present, they are stored by an SCP. It is recognized that in some cases the digital image acquisition system will not have a user interface or direct connection that allows acquisition of these parameters, even if device or therapy have been used.
The Common Frame of Reference Information Entity Modules, X-Ray Collimator Module, DX Positioning Module and X-Ray Tomography Acquisition Module are User optional, though it is desirable that, if present, they are stored by an SCP. It is recognized that in some cases the parameters of the mechanical devices used for collimation, positioning and tomography may not be available to a digital image acquisition system that is not integrated with the X-Ray generation and positioning system.
The Image Histogram Module may contain a single or multiple statistical representations of the pixel data used to derive the VOI LUT Module, or intended to be used to derive or replace the VOI LUT Module. The Image Histogram Module may contain statistics of a subset of the stored image pixel data (such as from a cropped area or region of interest that is not the full field of view) that are useful for deriving a better VOI LUT than might be derived from the statistics obtained from the entire stored pixel data.
The Specimen Identification Module (Retired) was previously included in this IOD but has been retired, and its functionality replaced by the Specimen Module. See PS3.3-2008.
The VOI LUT Module Attributes and behavior are further specialized in the DX Image Module.
The Curve Module (Retired) was previously included in this IOD but has been retired. See PS3.3-2004.
