となる。2. Description of the Related Art In a third-generation scanner in which an X-ray tube and a detector rotate together, a cable is generally connected between the high-voltage generator and the X-ray tube. The X-ray tube cannot be rotated in the same direction many times. In other words, it is necessary to reverse the rotation direction of the rotating part that holds the X-ray tube and the detector for each scan (every one rotation), which causes a pause time between scans and a high-speed scan. In order to realize the above, the impact on the X-ray tube due to the start and stop of rotation becomes a particular problem.
