Paper Abstract

To provide real-time x-ray imaging, industry relies almost entirely on the combination of the x-ray image intensifier and the high-performance television camera. Although these devices have ben pushed to remarkable degrees of performance, they remain complex electro-optical assemblies with significant built-in errors, instabilities and degradation mechanisms. We describe a replacement for these system utilizing as a sensor a large array of amorphous silicon photodiodes and thin-film switching transistors. Specifically, the equipment described is a replacement for a 9-inch dual-mode x-ray image intensifier with a high performance 2000-line digital tv camera capable of operating in both real-time video radioscopic and high-performance radiographic modes.
