To provide a nuclear medicine diagnostic equipment in which the position resolution of data is enhanced, in which satisfactory data can be obtained by reducing the influence of a scatterer and an absorber, which reduces the burden on the subject by shortening the data acquisition time.

By using a plurality of semiconductor detectors (three detectors in the figure) 11, the data is acquired in the three-dimensional projection direction (six directions in the figure) anticipating an object Q to be measured from the best positions, with reference to the object Q to be measured [from two positions as the left-side face position (under the armpit) 1 and the left front position 1 of the subject]. When the data is acquired in the three-dimensional projection direction, anticipating the object Q to be measured from the best positions with reference to the object Q to be measured, the position resolution of the acquired data is enhanced, the influence of the scatterer and the absorber is reduced, and satisfactory data can be obtained. An image can be reconstructed with a very small number of times of data acquisition operations.
