Photon Detector Breathes New Life Into CT Imaging
BETHESDA, Md., Aug. 16, 2022 — The Food and Drug Administration has cleared a photon-counting detector (PCD)-based CT system for clinical use. The system, which has been under development by a team at the Mayo Clinic for a decade, offers an alternative approach to the conversion of x-rays to electrical signals. Among the benefits of the PCD-CT system, according to its developers, are a reduction in noise compared to traditional CT images, as well as improved spatial resolution.
