TID 4020 CAD Image Library Entry Template

Each instance of the Image Library Entry template contains the Image SOP Class and Instance UIDs, and selected attributes for an image. If values for the attributes are not present in the Image SOP Instance, then as many of the attributes as possible should be derived.

Parameter Name Parameter Usage
$ImageLaterality Coded term or Context Group for Image Laterality
$ImageView Coded term or Context Group for Image View
$ImageViewMod Coded term or Context Group for Image View Modifier
