PROBLEM TO BE SOLVED: To provide a nuclear medicine diagnostic apparatus for substantially improving inspection efficiency by efficiently arranging a plurality of detectors and detecting radiation while moving them in the nuclear medicine diagnostic apparatus having the plurality of detectors. SOLUTION: Two of the detectors 21a-21c, for example, detectors 21b and 21c are arranged at opposite locations which sandwich a heart part Q of a subject P. The remaining one, the detector 21c, is arranged at a location which covers both the heart part Q of the subject P and its periphery and forms an approximately U-shape with the other detectors 21b and 21c. While the detectors 21a-21c are moved and rotated by 180°on the heart part Q of the subject P, data is collected. By this, projection data of the amount of two detectors is acquired within the range of 180°on the side of cardiac muscle of the presence of the heart part Q, an important range at the processing of image reconstruction. Projection data of the minimum amount of one detector is acquired within the range of 180°on the opposite side to the cardiac muscle, a range for correcting distortion at the processing of image reconstruction.
