装置のＸ線照射野調整機構。In the X-ray field adjustment mechanism of an X-ray CT device, the X-ray field adjustment mechanism of an X-ray CT device determines the X-ray field by photographing the focal point of the X-ray tube on film and aligning this focal point with the center of the X-ray detector. The present invention is characterized by comprising a film cassette having an opaque marker for introducing X-rays, and a positioning mechanism that aligns the center position of the film cassette with the center position of the X-ray detector when they are set respectively. X-ray CT
X-ray irradiation field adjustment mechanism of the device.
