Claim One:
1. An X-ray image formation device comprising: an X-ray measurement unit which obtains X-ray detection data by radiating X-rays to a subject in a manner to circle around the subject and detecting the X-rays; a body movement measurement unit which obtains body movement period data related to a periodic body movement of the subject; a circling controller which controls the circling of the X-rays by the X-ray measurement unit based on the body movement period data such that a body movement periodic component in the X-ray detection data obtained for each round of circling is shifted in the X-ray detection data for a plurality of rounds of circling; and an image formation unit which forms image data of the subject while correcting the body movement periodic component based on the X-ray detection data obtained by the plurality of rounds of circling, wherein the circling controller executes a control to add another round of circling of the X-rays when the body movement periodic components overlapped with each other remain in the X-ray detection data obtained by a normal number of rounds of circling which is set in advance.
