CdS heterojunction contacts for CZT photon counting X-ray detectors

X-ray CT scanners and Magnetic Resonance Imaging have been described as the most important advances in medical technology in the last century. Further improvements in CT scanners will be possible with CZT photon counting detectors which are being implemented in next generation CT scanners. Improvements enabled by photon counting CZT detectors include faster imaging, meaning image quality is less sensitive to patient movement, higher resolution, tissue sensitivity and lower X-ray dose. The goal of this project is to further improve reliability, charge extraction and background noise in CZT detectors through refinements in electrical contacts.
