Abstract
In the case where X-ray tubes and X-ray detectors have fixed directions (directions of irradiation and directions of detecting planes), X-ray fluoroscopy can be carried out from various directions by providing two U-shaped tracks for the X-ray tubes and the X-ray detectors, each having two straight tracks arranged opposite each other, and a curved track connected thereto. An increased number of directions for X-ray fluoroscopy can be secured by arranging a U-shaped track rail for the X-ray tubes and a U-shaped track rail for the X-ray detectors opposite each other when seen in plane view.
