Attribute Name	Tag	Type	Attribute Description
Contributing Sources Sequence	(0018,9506)	1	A Sequence that describes characteristics of the sources that are used to create a derived SOP Instance. One or more Items shall be included in this Sequence.
>Include Table 10-13 “General Contributing Sources Macro Attributes”
>Include Table 10-14 “Contributing Image Sources Macro Attributes”
>Acquisition Device Processing Description	(0018,1400)	1C	Indicates any visual processing performed on the frame prior to exchange. See Section C.8.7.1.1.3. Required if present and consistent in the contributing SOP Instances.
>Acquisition Device Processing Code	(0018,1401)	1C	Code representing the device-specific processing associated with the frame (e.g., Organ Filtering code). Required if present and have an equal value in the contributing SOP Instances.
>Imager Pixel Spacing	(0018,1164)	1C	Physical distance measured at the receptor plane of the detector between the centers of each pixel specified by a numeric pair - row spacing value (delimiter) column spacing value in mm. Required if present and consistent in the contributing SOP Instances.
