Claim:
1. A radiation imaging apparatus, comprising: an imaging means for irradiating radiation; a radiation detector for detecting the radiation of a subject positioned between the irradiating radiation and the radiation detector; and a moving means for moving the imaging means and/or the radiation detector; the radiation imaging apparatus being configured to perform a plurality of imaging operations of a subject by moving the imaging means and/or the radiation detector; and the radiation imaging apparatus further comprising: wherein the radiation imaging apparatus moves the radiation detector, irradiates radiation which has passed through the subject onto the radiation detector each time that the position of the radiation detector changes by being moved, and obtains a plurality of radiation images, at least portions thereof being overlapped, wherein the imaging means moves the radiation detector along a predetermined axis of movement and irradiates radiation which has passed through the subject onto the radiation detector each time that the position of the radiation detector changes due to the movement and wherein the radiation imaging apparatus further comprises: wherein the body movement obtaining means obtains the amounts of body movement of the subject during the imaging operations, based on the amounts of shift, wherein mechanical error includes inclinations of an imaging surface.
