PROBLEM TO BE SOLVED: To provide the timewisely successive plural tomographic images of the same phase equivalently even in the case that a scanning object makes irregular periodic motions. SOLUTION: Data are grouped corresponding to the R-R interval (irregular periodsτ1,τ2,τ3 andτ4) of electrocardiograph signals and the plural timewisely successive X-ray CT images S1, S2, S3 and S4 of the same phase equivalently are generated based on the data of respective group G. Thus, the heart disease of unstable heartbeats is more accurately diagnosed.
