PROBLEM TO BE SOLVED: To provide a tomographic image at a widely enhanced data-collecting rate viewing from a data-processing aspect while allowing for the adoption of an X-ray flat-panel detector by thinking out a method for collecting/storing output signals and data processing. SOLUTION: A data-collecting part 35 repetitively reads data into specific regions with respect to the X-ray flat-panel detector 5 and make a data memory 33 store the output signals in sequence every rotating angle. In addition, a data processing part 39 executes processing for CT (computed tomography) to reconstruct tomographic images by collectively processing the output signal every rotating angle. Thereby tomographic images can be obtained by significantly enhancing an image photographing data collection rate from the viewpoint of the data processing part 39 in comparison to the data collection rate at the time of perspective image photographing.
