TID 4020 CAD Image Library Entry
Prev | Mammography CAD SR IOD Templates | Next

### TID 4020 CAD Image Library Entry

Each instance of the Image Library Entry Template contains the Image SOP Class and Instance UIDs, and selected attributes for an image that facilitate spatial analysis without having to retrieve the entire set of referenced images. If values for the attributes are not present in the Image SOP Instance, then as many of the attributes as possible should be derived.

Table TID 4020. Parameters

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

Type:

  Extensible

Order:

  Significant

Root:

  No
