A.55 Breast Tomosynthesis Image IOD

A.55.1 Breast Tomosynthesis Image IOD Description

This Section defines the Information Object for multi-dimensional reconstructed breast tomosynthesis X-Ray Images that includes those data elements and information objects necessary for the interchange of multi-dimensional breast tomosynthesis X-Ray volumes.

Note

This IOD is not intended for interchange of source projection x-ray images.

A.55.2 Breast Tomosynthesis Image IOD Entity-Relationship Model

A.55.3.1.1 Restrictions for Standard Extended SOP Classes

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

Note

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

A.55.3.1.2 Image - Equipment Coordinate Relationship Module

For Breast Tomosynthesis Image SOP Instances created from SOP Instances of the Breast Projection X-Ray Image SOP Classes (1.2.840.10008.5.1.4.1.1.13.1.4 or 1.2.840.10008.5.1.4.1.1.13.1.5) the isocenter coordinate system shall be used to describe the positioning of the X-Ray Source, Detector and Breast Support (see Section C.8.31.6), and shall use only the value ISOCENTER for Equipment Coordinate System Identification (0028,9537).
