Abstract
An X-ray computer tomography (CT) apparatus according to an embodiment includes an X-ray source, an X-ray detector, and generating circuitry. The X-ray source radiates X-rays. The X-ray detector includes a scintillator including a first region close to the X-ray source and a second region distant from the X-ray source, an optical sensor that detects scintillator light obtained by converting the X-rays radiated from the X-ray source with the scintillator, and a variable layer that is provided in the scintillator and switchable between a first state in which the variable layer transmits the scintillator light between the first region and the second region and a second state in which the variable layer does not transmit the scintillator light between the first region and the second region. The generating circuitry generates a CT image based on a signal output from the X-ray detector.
