An X-ray computerized tomography (CT) apparatus including a cyclic movement detector to detect a cyclic movement of at least a part of a living body to be examined, and producing an output signal representing the cyclic movement, a rotational member support an X-ray source and an X-ray detector, and rotating around the living body, a driving mechanism to drive a rotation of the rotational member, and a control unit to control a rotational speed of the rotational member in accordance with the output signal indicative of the cyclic movement from the cyclic movement detector, so that the X-ray detector collects total scan data for reconstructing a single slice starting at a predetermined phase of a signal cycle of the cyclic movement of the part of the living body, and not ending until immediately before a corresponding phase of a next cycle of the cyclic movement.
