A preliminary design for an image sensor with a sensitive area of 10 x 10 with 1280 x 1280 pixels coupled to an optimized high-efficiency scintillator Csl(TI) as an x-ray converter is presented. The digital image system has a sensitive area and an image resolution comparable to the traditional screen-film combination, but it has potentially much higher sensitivity and dynamic range.
