A.48 Enhanced XRF Image IOD

A.48.1 Enhanced XRF Image IOD Description

The focus for this Enhanced XRF IOD is to address the requirements for image transfer found in general Radiofluoroscopic applications performed on a table with a column. For applications performed on X-Ray RF acquisition systems that support a Patient-Based Coordinate System with cranial/caudal, LAO/RAO angles, etc. the Enhanced XA Image IOD may be used.


  1. An example of a case where the Enhanced XA Image IOD may be preferred to the enhanced RF IOD are RF acquisition system equipped with an X-Ray source and an image Receptor positioned by what is generally called a C-arm (e.g., Interventional Procedures, Myelography, Biopsy, and Neurology).

  2. For the purpose of X-Ray Radiofluoroscopy, this 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.

  3. 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, a Series may be defined as comprising a set of images (single or multi-frame) associated with one such process within a Study.
