A.48.1 Enhanced XRF Image IOD Description​

ThefocusforthisEnhancedXRFIODistoaddresstherequirementsforimagetransferfoundingeneralRadiofluoroscopicapplications​ performed on a table with a column. For applications performed on X-Ray RF acquisition systems that support a Patient-Based Co-​ ordinate System with cranial/caudal, LAO/RAO angles, etc. the enhanced XA Image IOD may be used.​

Note​

1.​AnexampleofacasewheretheenhancedXAIODmaybepreferredtotheenhancedRFIODareRFacquisitionsystem​ equipped with an X-Ray source and an image Receptor positioned by what is generally called a C-arm (e.g., Interven-​ tional 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.​
