Abstract

To provide real-time imaging, x-ray diagnostic imaging relies entirely on the combination of the x-ray image intensifier and the high-performance television camera. Although these devices have been 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 systems utilizing as a sensor a large array of amorphous silicon photodiodes and thin-film switching transistors. Specially, 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 and high-performance spotfilm modes.
