PROBLEM TO BE SOLVED: To provide an X-ray CT scanner capable of exposing with less X-ray to a test subject from a plurality of vessels and imaging with time resolution and FOV according to the diagnostic purpose, and to provide the data processing method thereof. SOLUTION: An X-ray CT scanner includes X-ray tubes including a first X-ray tube and a second X-ray tube having fan angles different from each other, X-ray detectors including a first X-ray detector and a second X-ray detector which are respectively arranged to face the first X-ray tube and the second X-ray tube, collection data processing means for executing weighting processing to each of the pieces of collection data including first collection data Ds1 obtained by the first X-ray detector and second collection data Dm obtained by the second X-ray detector to generate image data combined to be smooth in a direction corresponding to a channel direction of detection elements provided in the plurality of X-ray detectors, and image generating section for performing processing including image reconstruction processing with respect to pieces of collection data Dws1, Dwm weighted by the collection data processing section to generate image data I.
