ABSTRACT:
A CT scanner which collects X-ray projection data of a subject and which generates an image in the subject from the projection data, the CT scanner includes tubes which emit X-rays and which include grids to switch emission and stoppage of the X-rays, a unit which generates a high voltage to be supplied to the tubes, a cable which sends the high voltage to each of the tubes, circuits which change potentials of the grids arranged in the tubes, respectively, a control unit which controls the circuits to switch the emission and the stoppage of the X-rays in a pulse manner while the tubes rotate around the subject, detectors arranged to face the tubes, respectively, and a unit which validates an output signal from the detector facing the tube emitting the X-rays and which invalidates an output signal from the detector facing the tube stopping the emission of the X-rays.
