WebJan 28, 2024 · PCDs for x-ray CT are so-called direct-conversion detectors, wherein the x-ray photons are converted directly into an electric signal as opposed to first being converted to visible light. PCDs for CT generally consist of semiconductor sensors with an applied bias … WebAug 11, 2024 · In addition, conventional CT does not provide information on the energy associated with each X-ray photon because intensity is rather high, typically amounts to 10 7 − 9 cps / mm 2. Here, we propose a novel, low-dose photon-counting CT system based on a multi-pixel photon counter (MPPC) and a high-speed scintillator.
