A.54 X-Ray 3D Craniofacial Image IOD

A.54.1 X-Ray 3D Craniofacial Image IOD Description

This Section defines the Information Object for multi-dimensional reconstructed cone beam X-Ray Craniofacial Images and includes those data elements and information objects necessary for the interchange of Multi-dimensional X-Ray volumes.

Examples of X-Ray 3D Craniofacial Images are: 3D reconstruction of craniofacial structures for surgical placement of implants, dimensional analysis for orthodontic therapy and evaluation of craniofacial pathology.

A.54.2 X-Ray 3D Craniofacial Image IOD Entity-Relationship Model

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 Craniofacial Image IOD.

A.54.3.1.1 Modality Type Attribute

The Modality Type attribute (0008,0060) shall have the value DX.

A.54.3.1.2 Restrictions for Standard Extended SOP Classes

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 Craniofacial Image.

Note

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

  2. The Curve Module was previously included in the Image IE for this IOD but has been retired. See PS3.3-2004.
