A nuclear medicine diagnostic apparatus for detecting gamma rays emitted from a radioisotope (RI) administered to a subject, to generate images showing the functions of the subject, such as metabolism. In the nuclear medical diagnostic apparatus, a detector detects the gamma rays from at least three different three-dimensional detection directions and an image processor reconstructs images from the projection data by an iterative reconstruction method. Therefore, the apparatus can collect data which is high in spatial resolution and low in absorption and scatter. Moreover, it can shorten the data collection time and reduce the burden on the subject patient.
