Abstract

Large area amorphous silicon image sensor arrays are important for x-ray medical imaging and document scanning as well as a variety of other applications where large sensor size is required. The paper first summarizes the present state of the flat panel x-ray imager technology, and compares the two main approaches for x-ray detection. We then describe the performance of a new, large area, high resolution, radiographic imager based on a single amorphous silicon array with 2304×3200 pixels, and an active area of 30×40 cm (12×1 6”).
