PROBLEM TO BE SOLVED: To reduce a positional fluctuation of a subject image on a video that results from mechanical movements due to a rotation of a support. SOLUTION: An X-ray computerized tomographic apparatus includes an X-ray tube 101, an X-ray detector 103, a rotating mechanism unit 102 which continuously rotates the X-ray tube around a subject to be examined together with the X-ray detector, a data storage unit 112 which stores projection data corresponding to an output from the X-ray detector in association with the angles of the X-ray tube at the time of data acquisition, a reconstruction processing unit 114 which reconstructs a plurality of images on the basis of a plurality of projection data sets stored in the data storage unit, the plurality of projection data sets corresponding to the same range from a first view angle to a second view angle, and a display unit 116 which displays the plurality of reconstructed images.
