PROBLEM TO BE SOLVED: To provide a radiographic apparatus capable of creating a clear tomographic image with no deviation even if no marker is photographed.SOLUTION: According to the X-ray photographing apparatus of the present invention, a clear tomographic image with no deviation can be created even if no marker is photographed. In the structure of the present invention, in order to calculate a correction value for canceling the deviation of a subject image, the subject image itself is used. Different from a marker, a subject image is not photographed clearly on an X-ray image. This is because a subject has a thickness and the inner structure of the subject is photographed on an X-ray image, with the inner structure folded and piled up. Thus the present invention is configured such that a provisional tomographic image is created to determine how the subject image is deviated, and a correction value calculation unit 13 calculates the direction and intensity of the deviation of the subject image on the basis of the tomographic image.SELECTED DRAWING: Figure 1 |
