PROBLEM TO BE SOLVED: To enhance precision for absorption correction, and to conduct data collection operation for the absorption correction, in parallel with the collection operation for gamma rays for imaging. SOLUTION: This nuclear medicine diagnostic equipment is provided with main detectors 15, 17 provided with a photomultiplier for detecting the gamma rays emitted from a radioactive isotope administered to a subject; a radiation source 23 for emitting gamma rays; a semiconductor detector 25 for detecting gamma rays emitted from the radiation source and transmitted through the subject; a processor 63 for imaging an in-body distribution of the radioactive isotope, based on outputs from the main detectors and an output from the semiconductor detector; and a slide arm 29 for moving the semiconductor detector with respect to the main detectors, to move the semiconductor detector along a normal direction of a detection face in each of the main detectors.
