PROBLEM TO BE SOLVED: To provide an X-ray computed tomograph which enables taking of multiple time phase images free from vertical movement by breathing. SOLUTION: A respiration sensor 50 and an electrocardiograph 48 are mounted on a subject to collect production data by the combined time length of one heart beating cycle and one rotation cycle of an X-ray bulb synchronizing an electrocardiogram only during a period (exhalation) with relatively limited of vertical movement of a heart based on both outputs of the respiration sensor 50 and the electrocardiograph 48. Data per rotation are taken out centering around each time phase within one heart beating from the collected data to reconstruct images of respective time phases.
