WebApr 9, 2024 · What is Photon Counting in X-ray Imaging? Inside a photon counting detector, the resulting charge distribution of each single interaction between incident X-rays and the active detector material is recorded separately. This enables photon-counting technology to extract energy resolved information on a per-interaction basis. WebPhoton-counting computed tomography (PCCT) is a form of X-ray computed tomography (CT) in which X-rays are detected using a photon-counting detector (PCD) which registers the interactions of individual photons. By keeping track of the deposited energy in each interaction, the detector pixels of a PCD each record an approximate energy spectrum, …
