The FDA has granted clearance of Siemens Medical Solutions Inc.’s photon-counting computed tomography (CT) scanner, Naeotom Alpha. The new diagnostic imaging device uses a photon-counting detector that measures individual X-rays that pass through a patient's body, as opposed to current systems that use detectors that measure the total energy contained in X-rays at once. The scanner then transforms the information from the X-ray photons into a detailed three-dimensional image, which can be used by physicians to assist diagnosis or treatment preparation planning.
