To count or to integrate? That is a profound question. To answer it scientifically, we will review the essence of photon counting imaging, which is not about the direct conversion of radiation into charges, nor about the radiation sensor material; instead, it is all about the electronic readout mode. After drawing a unified picture of PCDs, the talk will focus on a subtype—semiconductor-based PCDs—in which photon counting imaging finds synergy with the direct-conversion detection method.
