Abstract
An X-ray tube support apparatus includes: an X-ray tube support mechanism for supporting an X-ray tube to be vertically extendible/movable; a guide unit, having moving paths which allow movement in two-dimensional directions parallel to a ceiling surface, for supporting the X-ray tube support mechanism, and guiding the X-ray tube to a central position of one photographing table; a plurality of position sensors, arranged in a vertical moving path of the X-ray tube support mechanism, and two-dimensional moving paths to the central position of the photographing table, for detecting vertical and two-dimensional moving positions of the X-ray tube support mechanism; a plurality of fixing units, arranged in the two-dimensional moving paths of the guide unit and the vertical moving path of the X-ray tube support mechanism, for fixing the X-ray tube support mechanism at each moving position; and a determination unit for storing position data in accordance with the central position of the photographing table and a set distance from a focal point of the X-ray tube to an X-ray photographing system, comparing the position data with a position detection signal of the position detected by each po…
