PROBLEM TO BE SOLVED: To provide an imaging medical examination apparatus and method which expands the coverage of the reconstruction of a picture in connection with the examination of a movable object to be examined by a CT scanner or C arm apparatus. SOLUTION: A lot of rotary movement (Rm, n= 1, 2,∼M) which covers the same angular range (α<SB>max</SB>) of a base (7) which supports an X-ray source (2) and a detector (5) respectively is produced, and a measured data set is generated respectively during a lot of measuring intervals (Dnm, n=1∼N, m=1∼M) in a method to obtain three dimensional measured data of an object to be examined moving periodically by cycle time (T<SB>RR</SB>). A turnover period (T<SB>rot</SB>) of rotating is set so that a lot of phase intervals of periodic movements to scan by a measuring interval (D<SB>nm</SB>) arise in each rotary movement (Rm). A synchronizing signal derived from periodic movement of the object to be examined is used for scanning the same phase intervals of periodic movements respectively at the measuring interval (D<SB>nm</SB>).
