PROBLEM TO BE SOLVED: To provide radiographic equipment capable of executing tomography by a novel imaging method. SOLUTION: This radiographic equipment is so constituted that an X-ray tube moves parallel along a perpendicular direction to the body axis, the longitudinal direction of a subject. Also, the equipment is constituted that the X-ray tube intermittently irradiates X-rays whenever the X-ray tube moves for every pitch, and an FPD detects the X-rays intermittently irradiated and transmitting through the subject. X-ray images O<SB>1</SB>, O<SB>2</SB>,...,O<SB>I</SB>,... and O<SB>M</SB>are resolved for every pitch, and the resolved images are composed for every same projection angle in order to obtain projection images P1, P2, etc. for every projection angle. This radiographic equipment can thus execute the tomography by the novel imaging method by executing a reconstruction process based on the composed projection images. COPYRIGHT: (C)2008,JPO&INPIT
