<p>The present invention is provided with the following: a laser marker (51) that is disposed on an X-ray irradiation axis connecting an X-ray tube (21) and an X-ray detector (22) of a video system (2) and shines laser light (O) towards said X-ray detector (22); and a mirror (61) provided on at least the middle section of the X-ray detector (22) of the video system (2). The laser light (O) emitted by the laser marker (51) is reflected by the mirror (61), making it easy to check and adjust the alignment of the video system (2) by checking the reflected light (R) therefrom.</p> |
