Abstract
An ionizing radiation detector, such as a photon counting computed tomography detector, includes a semiconductor material plate, a plurality of anodes located on a first side of the semiconductor material plate, where the gaps (i.e., streets) between adjacent anodes are less than 15 μm in width, and at least one cathode located on a second side of the semiconductor material plate. Ionizing radiation detectors according to various embodiments may have improved count rate stability (CRS) characteristics and a reduced number of Non-Conforming Pixels (NCPs) relative to conventional detectors.
