SpletA PCCT measures each photon and its energy directly, whereas with a conventional energy integrating detector (EID) the incident photons are not directly converted to signal. Rather, the absorbed energy of the photons is first converted to light by a scintillator, then that light is converted to an electrical signal by a photodiode. Splet11. apr. 2024 · Photon-counting computed tomography (PCCT) is a new technology that enables higher spatial resolution compared to conventional CT techniques, energy resolved imaging and spectral post-processing. This leads to improved contrast-to-noise ratio, artifact and potential dose reduction as well as elimination of electronic noise.
