PROBLEM TO BE SOLVED: To suppress, in a Talbot interferometer or a Talbot-Lau interferometer including an X-ray detector constructed by arranging a plurality of radiation detection element arrays, an influence on a diagnostic image due to overlapping between an area of interest and a junction part between the radiation detection element arrays at the time of imaging.SOLUTION: At an X-ray imaging device 1, a subject table 13 is provided with an interest area placing unit 131, on which an area of interest of a subject is placed, in which arrangement is made so that when viewed in an X-ray irradiation direction, junction parts 161 and 162 between radiation detection element arrays 16a to 16d of an X-ray detector 16 do not overlap the interest area placing unit 131. |
