However, the CMOS image sensors can provide stronger anti-radiation capacity than CCD as well as Single Chip Integrating with image sensors array, drive and control circuit, signal processing circuit, A/D conversion circuit and Completely Digital Interface Circuit. The CMOS image sensors also possess high quantum efficiency, wide spectral response, good response uniformity, low supply voltage and low request of clock. At the same time, the small bulk, high reliability, low power consumption and low cost are the prominent advantages of the CMOS image sensors too, thus CMOS image sensor has more exploiture foreground in X-ray real-time radioscopy imaging system.
