Abstract

The authors investigate the potential application of a novel 2048X2048-matrix image intensifier (II)/TV based real-time digital radiography system for GI-tract examinations. The basic imaging properties of the system and clinical image evaluations have been studied. Imaging properties measured have been compared with those of the conventional screen/film system, computed radiography system (CR), and 100-mm roll-film system. It was found that this DR system can be applied not only to mass screening but to accurate imaging in gastrointestinal examinations.
