Abstract:
1. A nuclear medicine diagnosis apparatus comprising: a light signal generating unit configured to repeatedly generate light signals; a photodetection unit configured to repeatedly detect the generated light signals, repeatedly generate first output signals corresponding to intensities of the detected light signals, repeatedly detect gamma rays emitted from a subject, and repeatedly generate second output signals corresponding to intensities of the detected gamma rays; a measurement unit configured to repeatedly measure light signal detection times of the light signals in the photodetection units and repeatedly measure gamma ray detection times of the gamma rays in the photodetection unit; a calculation unit configured to calculate a difference between a target gamma ray detection time and a target light signal detection time of the light signal detection times for each of the gamma ray detection times, the target light signal detection time being measured before the target gamma ray detection time; and a storage unit configured to store the calculated difference in association with a target second output signal of the second output signals.
