Radiological image intensifier television systems have been investigated as an adjunct to quality control and optimisation of exposure. The work has demonstrated the need for much further study of image uniformity and noise. While the study was originally aimed at digital systems using fluoroscopic technology, it is now clear that the fluoroscopy units in their own right are far from optimised. Clearly very large amounts of nonuniformity are routinely accepted and the performance of automatic exposure control systems is not directly related to simple markers of image quality.
