Abstract: PROBLEM TO BE SOLVED: To execute mapping to a three-dimensional voxel without the rotation or parallel movement of a physical detector concerning an X-ray source by processing an image on the detector to be warped onto the surface of a virtual detector which is fixed at interval concerning the X-ray source. SOLUTION: Energy for penetrating an object 130 is irradiated from the X-ray source 100 attached to one end side of a C arm 120 rotating with the object 130 as a center toward the detector 140 which is attached to the other side of the C arm 120 so that the image is formed on the surface of the detector 142.
