PROBLEM TO BE SOLVED: To provide a radiographic apparatus which can clearly acquire a projection image when viewing a subject from an oblique direction, and allows adjustment of a projection direction of the projection image without performing second photography.SOLUTION: An X-ray photographing apparatus 1 consecutively photographs images while moving an X-ray tube 3 and an FPD 4 to the same direction or directions opposite to each other to acquire voxel data B of an acquired subject, and acquires an image (a reconstruction image P1) corresponding to the projection image acquired by spot photography by use thereof. Because the reconstruction image P1 of the radiographic apparatus is generated by projecting the voxel data B onto a virtual plane, distortion does not occur in the image. If having generated the voxel data B once, a plurality of reconstruction images P1 having different projection directions can be generated without performing photography of the subject M any more, and the apparatus has excellent operability while suppressing exposure to the subject M. |
