Patent ID: 7964849

Claim:
A nuclear medical diagnosis apparatus, comprising an image pickup device including: a plurality of radiation detectors that detect radiation from a test object or radiation passing through the test object; and a signal processing device connected to each of the radiation detectors, the signal processing device processing an output signal from the radiation detector, the nuclear medical diagnosis apparatus generating an image based on information on detected radiation outputted from the signal processing device of the image pickup device, wherein the signal processing device comprises: a determination unit that determines whether an output signal from the radiation detector is an intended radiation detection signal or a noise; a counting unit that counts for the radiation detector a number of times the output signal from the radiation detector is determined as a noise; and a control unit which, based on the number of times the output signal from the detector is determined as a noise, determines a relevant radiation detector as faulty, and which controls so as not to process an output signal from the radiation detector that is determined as faulty, and when it is determined that the radiation detector that had been determined as faulty has returned to a normal state, the control unit processes a detection signal from the radiation detector that has returned to the normal state.
