A physics primer on photon‐counting detectors in CT: Physics, signal formation, and performance

open access: yesMedical Physics, Volume 53, Issue 8, August 2026.
Abstract Photon‐counting detector CT (PCD‐CT) is moving from laboratory development to clinical deployment. However, its threshold‐bin data arise from a tightly coupled detector–readout chain that can be difficult to understand as a whole. These data are not a direct readout of photon energy, but the outcome of a sequence of physical and electronic ...
