PROBLEM TO BE SOLVED: To provide an X-ray CT apparatus by which a plurality of cross section images at a phase of periodic motion of a scan object are effectively created. SOLUTION: Data are collected from helical scan data. A phase of periodic motion of a scan object corresponding to a time point collecting the data and a position on a linear motion axis are acquired while corresponding each other. Images on a plurality of positions corresponding to a same phase on the axis are respectively created. Images positioned between a plurality of positions are created by arithmetic interpolation using the created images. Thereby, a plurality of cross section images at a phase of periodical motion of the scan object can be created only by several rotations of scanning. COPYRIGHT: (C)2007,JPO&INPIT
