PROBLEM TO BE SOLVED: To produce a three-dimensional image even during measurement by obtaining three-dimensional image data by synthesizing three-dimensional image data obtained just before renewed positions and two-dimensional CT data at the renewed positions when obtaining three-dimensional image data from an optional start position to the renewed positions. SOLUTION: After a subject (patient) 4 is laid recumbently on a bed 3, and a measurement position is aligned with an affected part, X rays are radiated from an X-ray generator 6, and X rays that transmits the subject 4 are measured with a detector 7. Data on the dose of X rays measured are transferred to an image processing unit 9, and an image is produced by image reconstruction. On this occasion, when producing an image while renewing the position from the optional start position, three-dimensional image data from the start position to each of the renewed positions are obtained, and by synthesizing three-dimensional image data obtained just before the renewed positions and two-dimensional computerized tomogram data at the renewal positions, three- dimensional image data from the start position to the renewed positions are obtained. |
