PROBLEM TO BE SOLVED: To enable image data to be generated by changing reconfiguration conditions depending on a positional relationship of an observation object on the basis of projection data acquired with time by an X-ray CT apparatus.SOLUTION: A storage unit stores projection data on a movable region. A reconfiguration processing unit generates first image data on the movable region by applying reconfiguration processing to the projection data at a first frame rate. An extraction unit extracts a surface layer of the movable region from the first image data. An appearance photographing unit acquires an appearance image by photographing the movable region. An analysis unit compares the one appearance image with the surface layer extracted from each of the generated first image data, identifies scan timing of the first image data from which the surface layer having a substantially coincident shape is extracted, and sets a duration including the same. The reconfiguration processing unit generates second image data by applying reconfiguration processing to the projection data, in a range corresponding to the duration, at a second frame rate. |
