1. A nuclear medicine diagnostic device comprising processing circuitry configured to
obtain first photon-number information detected by a first detector,
calculate, based on the first photon-number information, a first light emission probability model corresponding to the first detector,
identify, based on the first light emission probability model, a first timing at which detection probability becomes equal to or greater than a predetermined threshold value,
measure a detection timing of an event detected by the first detector, and
correct the detection timing based on the first timing.
