Photon-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 … See more Often EIDs are used as a baseline for comparison when evaluating PCD performance capabilities. With this lens, there are several potential advantages of using a PCD over using an EID in CT imaging. These … See more Discrete energy-dependent detection When a photon interacts in a PCD, the amplitude of the resulting electrical pulse is roughly … See more Experimental PCDs for use in CT systems use semiconductor detectors based on either cadmium (zinc) telluride or silicon, neither of which … See more Classical CT reconstruction The fundamental challenge of tomographic reconstruction is the inverse problem of reconstructing the … See more WebJul 27, 2024 · A single-photon emission computerized tomography (SPECT) scan lets your doctor analyze your body's organs, tissue and bones.
