ENERGY-SELECTIVE X-RAY RADIATION DETECTION SYSTEM

摘要

An X-ray detection system includes at least two electrodes constructed and cooperatively arranged at a photoconductive material to provide an electric field inside the material in a first direction, an X-ray shield and an X-ray window, a read-out circuitry, and a processing circuitry. The X-ray shield and the X-ray window are constructed and arranged to direct X-rays into the photoconductive material in a selected X-ray direction substantially different from the first direction, wherein the directed X-rays are absorbed at a location inside the photoconductive material at a depth corresponding to their energy. The read-out circuitry is constructed and arranged to receive electric signals corresponding to the absorption location inside the photoconductive material. The processing circuitry is constructed and arranged to determine the energy of the absorbed X-rays based on the electric signals.
