Paper Abstract

A large area self-scanned solid-state detector is being developed for digital radiology. It consists of an x-ray sensitive flat-panel employing amorphous selenium ((alpha) )-Se) as the x- ray transducer and active matrix integrated circuit for readout. In principle such detectors could be used for all the currently applied radiological modalities -- radiography, photofluorography, and fluoroscopy. Layers of (alpha) )-Se up to 500 micrometers thick are readout with an array of thin film field effect transistors. The whole structure is integrated onto a glass plate. For all practical purposes the resolution of the system is dictated by the pixel size and readout could be in real-time (i.e., 30 frames/sec).
