#### A.47.3.1 Enhanced XA Image IOD Content Constraints

##### A.47.3.1.1 Modality Attribute

Modality (0008,0060) shall have the value XA.

##### A.47.3.1.2 Overlay Plane, Curve, VOI LUT and Specimen Identification Modules

The Overlay Plane Module, VOI LUT Module and Softcopy Presentation LUT Module shall not be used in a Standard Extended SOP Class of the Enhanced XA Image.

### Note

1. The VOI LUT function is provided by a Frame VOI LUT Functional Group.

2. The Curve Module (Retired) was previously include in the list of Modules that shall not be present, but has been retired from DICOM. It is still not permitted to be present. See PS3.3-2004.

3. 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.

##### A.47.3.1.3 Positioner Type

Positioner Type (0018,1508) shall have the value CARM if the XA/XRF Acquisition Module is present.
