Abstract: A sensor installation structure includes: an exterior panel provided at a side part of a vehicle; an installation surface arranged at a location recessed inward in the vehicle width direction from a general surface of the exterior panel; a connecting surface connecting between a peripheral edge of the installation surface and the general surface; and a surroundings information sensor that detects surroundings information of the vehicle and that is located inward in the vehicle width direction from the installation surface. The connecting surface, in elevating from the peripheral edge of the installation surface toward the general surface, slopes so as to extend outward in the surface direction when viewed from the installation surface.

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.
