PROBLEM TO BE SOLVED: To obtain sharp images from which influences of scattered X-rays are removed. SOLUTION: A subject H is irradiated with two fan beam X-rays, and image data S1 based on the X-rays detected by an X-ray detector is collected by an image data collecting means and is stored in an image data storing means. Next, an X-ray tube and the X-ray detector are moved one pitch in the longitudinal direction of the subject H. The subject H is irradiated with two fan beam X rays from the X-ray tube in the position, and image data S2 based on the X-rays detected by the X-ray detector are collected and stored in the image data storing means. Then, the previous image data S1 stored in the image data storing means are subtracted from the collected image data S2 by an operating means, and divided data for one pitch, from which scattered X-ray image components are removed, are acquired. The imaging data for the subject H are obtained by joining the divided data, acquired by repeating those operations, by an image synthesizing means. COPYRIGHT: (C)2007,JPO&INPIT
