Photon counting detector pile-up correction
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 … WebThe Pile-Up effect describes the effects of photons lost at high photon count rates due to the dead time of the TCSPC devices. Most single photon counting detectors and TCSPC electronics have a dead time. After registering one photon the device needs some time to be ready for the next photon to detect. The dead time for TCSPC devices used for ...
