This Section defines the Information Object for multi-dimensional reconstructed cone beam X-Ray Angiographic Images and includes those data elements and information objects necessary for the interchange of Multi-dimensional X-Ray volumes.
Examples of X-Ray 3D Angiographic Images are: 3D reconstruction of static vascular structures (e.g., in Neuro-Radiology), ECG triggered cardiac volumes at different phases in the cardiac cycle, coronary artery tree reconstructions.
The E-R Model in Section A.1.2 depicts those components of the DICOM Application Information Model that directly reference the X-Ray 3D Angiographic Image IOD.

The Overlay Plane Module, VOI LUT Module and Softcopy Presentation LUT Module shall not be used in a Standard Extended SOP Class of the X-Ray 3D Angiographic Image.
The VOI LUT function is provided by a Frame VOI LUT Functional Group.
The Curve Module was previously included in the Image IE for this IOD but has been retired. See PS3.3-2004.
For X-Ray 3D Angiographic Images created from SOP Instances of the Enhanced XA SOP Class (1.2.840.10008.5.1.4.1.1.12.1.1) the isocenter coordinate system is used to describe the positioning of the table and positioner (see Section C.8.19.6.13), and shall use only the Defined Term ISOCENTER for Equipment Coordinate System Identification (0028,9537).
Table A.53-2 specifies the use of the Functional Group Macros used in the Multi-frame Functional Groups Module for the X-Ray 3D Angiographic Image IOD.
