PROBLEM TO BE SOLVED: To realize data interpolation and image reconstitution based on the data collected by a helical scan with a bed or a frame tilted in a multi-slice X-ray CT device. SOLUTION: In this multi-slice X-ray CT device, data processing means 10, 11 are provided with a data converting means converting the data, which are collected by a helical scan with a bed or a frame tilted, into parallel data and correcting means correcting the parallel data with the shift quantity of an X-ray effective path caused by the tilt of the X-axis (body axis). The data processing means 10, 11 helically interpolate the converted parallel data in the Z' axis direction perpendicular to the rotating surface of the frame. |
