A.28 Digital Intra-oral X-Ray image information object definition

A.28.1 Digital Intra-oral X-Ray Image IOD Description

The Digital Intra-oral X-Ray Image Information Object Definition specifies an image that has been created by an intra-oral projection radiography imaging device.

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

The Digital Intra-oral X-Ray Image IOD is used in two SOP Classes as defined in PS 3.4 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).
