Human Imaging With Photon Counting–Based Computed Tomography at Clinical Dose Levels

The purpose of this work was to measure and compare the iodine contrast-to-noise ratio (CNR) between a commercial energy-integrating detector (EID) computed tomography (CT) system and a photon-counting detector (PCD) CT scanner capable of human imaging at clinical dose rates, as well as to determine clinical feasibility using human cadavers.A research dual-source PCD-CT scanner was used, where the "A" tube/detector subsystem used an EID and the...
