French research lab CEA-Leti has created a novel x-ray photon-counting detector module (PCDM) for CT scanners, based on cadmium telluride (CdTe). CT scanners computer-process combinations of many X-ray images taken from different angles to produce 3D data. “Current x-ray CT scanners produce images with energy-integrating detectors [EIDs], which are based on indirect conversion technology: X-ray photons are first ...
