Digital fluoroscopy with a conventional fluoroscopic room and a nuclear medicine computer system.

The potential of a commercially-available nuclear medicine computer, with a digital video interface, supplied by its manufacturers, for digital fluoroscopy is described. In the absence of universally accepted standards against which the performance of digital fluoroscopy systems may be judged, the parameters included in the description of this system included linearity, uniformity, signal-to-noise ratio, matrix size at given frame rates and study sizes. In addition some examples of clinical studies involving subtraction are presented.
