A.47 Enhanced X-Ray Angiographic Image IOD

A.47.1 Enhanced XA Image IOD Description

This Section defines the enhanced Information Object for single plane X-Ray Angiographic Imaging that includes those Attributes and Information Objects necessary for the interchange of digital X-Ray Angiographic data. This includes images of the heart and all blood vessels.

The enhanced XA IOD is also applicable to clinical areas other than angiography (e.g., Interventional Procedures, Myelography, Biopsy/Localization, and Neurology).

Note

  1. For the purpose of X-Ray Angiography (XA), this enhanced IOD can be used to encode a single-frame image, or a Cine Run, or a single multi-frame image with non-time related dimensions.

  2. A typical Study might include all the images generated between the time a Patient gets on and gets off the procedure table. As several separable diagnostic or therapeutic processes may occur during a single Study (e.g., pre-intervention CA, left ventriculography, and post-intervention CA), a Series may be defined as comprising a set of images (single or multi-frame) associated with one such process within a Study.

  3. This enhanced IOD can be used to encode a single plane acquisition, or one plane of a biplane acquisition.
