## A.27 Digital Mammography X-Ray Image IOD

### A.27.1 Digital Mammography X-Ray Image IOD Description

The Digital Mammography X-Ray Image Information Object Definition specifies an image that has been created by a digital mammography projection radiography imaging device.

### Note

It meets all of the requirements of the DX IOD in Section A.26 in addition to those specified in this section.

The Digital Mammography Image IOD is used in two SOP Classes as defined in PS3.4 Storage Service Class, a SOP Class for storage of images intended for presentation, and a SOP Class for storage of images intended for further processing before presentation. These are distinguished by their SOP Class UID and by the Enumerated Value of the mandatory Attribute in the DX Series Module, Presentation Intent Type (0008,0068).
