Utilization of in-depth photon counting detectors towards x-ray spectral imaging: The benefits from the depth information

The in-depth photon counting x-ray detector (PCXD) is a multi-layer detector arrangement which has been introduced to tackle photon count rate limitations of current systems. The capability of resolving photon detections along the detector's depth direction enables multiple measurements in a single scan with energy information that could be potentially… (More)
