    • An X-ray computed tomography apparatus includes a cone beam X-ray tube, an X-ray detector, a rotating mechanism for supporting the X-ray tube and X-ray detector, a moving mechanism for moving the object in the slice direction, a control unit for controlling the rotating mechanism and moving mechanism to execute helical scan operation and move relative to the object, an input device for setting a substantially cylindrical reconstruction area, and an image reconstructing unit for reconstructing image data within the set reconstruction area based on the output of the detector. The apparatus also includes a movement distance determining unit for.determining the movement distance of the X-ray tube and X-ray detector relative to the object on the basis of the radius of the set reconstruction area as well as its height.
