PROBLEM TO BE SOLVED: To provide a three dimensional X-ray CT scanner capable of reducing artifacts of a reconfigured image even if a broad field of view is configured by arranging a plurality of two dimensional X-ray detectors in parallel. SOLUTION: In the three dimensional X-ray CT scanner, a sensitivity correction means 202, which corrects the output characteristic difference between the plurality of two dimensional X-ray detection means and read-out means is arranged and a three dimension X-ray image of a body to be inspected is reconstructed by inputting an X-ray detection data corrected with the sensitivity correction means into a three dimensional reconstruction means. The sensitivity correction means calculates a relative sensibility using the values of several pixels near the boundary of the detection area of which the plurality of two dimensional X-ray detection means and the read-out means take charge.
