X-RAY COMPUTED TOMOGRAPHY

摘要

PURPOSE: An X-ray computed tomography is provided to obtain a plurality of computed tomography images from a single rotation of the photographing device. CONSTITUTION: An X-ray computed tomography comprises a detection unit including a rotating disk(20) installed to a die(10) in such a manner that the rotating disk rotates by a servo motor(30), an X-ray tube(40) arranged onto the rotating disk, and an X-ray detector(50) arranged opposite from the X-ray tube, with a through hole formed at the rotating shaft of the rotating disk, between the rotating disk and the X-ray detector; a rubber screen(60) for covering the through hole, and which slides in such a manner that the position of the rubber screen is fixed even when the rotating disk rotates; and a control unit for generating a control signal to the servo motor such that the rotating disk rotates, stopping at an interval of 1 degree, generating a control signal for photographing an X-ray image of 1 frame during the stoppage of the rotating disk, to the X-ray tube and the X-ray detector, and processing images by putting the X-ray image into digital data format.
