Abstract
A nuclear medicine diagnostic device according to an embodiment includes processing circuitry. The processing circuitry obtains first photon-number information detected by a first detector; calculates, based on the first photon-number information, a first light emission probability model corresponding to the first detector; identifies, based on the first light emission probability model, a first timing at which the detection probability becomes equal to or greater than a predetermined threshold value; measures the detection timing of an event detected by the first detector; and corrects the detection timing based on the first timing.
