摘要： An X-ray computerized tomographic (CT) apparatus capable of facilitating alignment of focal spot position at the time of replacing an X-ray tube anew and capable of easily correcting the focal spot position even when the focal spot position of the X-ray tube is deviated. Thereby, the focal spot position of the X-ray tube remains fixed in a predetermined position. The X-ray computerized tomographic (CT) apparatus includes an X-ray tube which is freely movable in at least one of a horizontal direction and a vertical direction; a detection unit for detecting a dislocated degree of the focal spot position of the X-ray tube; and a controlling unit for automatically controlling the focal spot position of the X-ray tube based on data obtained from the detection unit so that the focal spot position of the X-ray tube remains fixed in a predetermined position. In a case where the CT apparatus is used for a helical scanning operation, the detection unit may further include a detection timing controller for controlling an instance of detection and alignment of the focal spot position by utilizing only an output of the X-ray amount detected at a predetermined position of a gantry.
