New 1-megapixel real-time CCD camera for high-end medical use

Even if standard x-ray image intensifier chains, medium resolution CCDs are now replacing conventional Vidicons, the introduction of high resolution CCDs for high end applications (high resolution fluoroscopy, digital radiography, digital subtraction angiography) has so far been less successful. Today, most of the CCDs do not fulfill the performance requirements requested for those applications. This document discusses the ideal characteristics for a high resolution CCD in terms of number of pixels, quantum efficiency, saturation charge capacity, to match with the resolution and the signal to noise ratio of the incoming image. The main performances of a camera incorporating such a CCD are discussed.© (1996) COPYRIGHT SPIE--The International Society for Optical Engineering.
