ABSTRACT:
A positron-computed tomograph device is enabled to suppress the noise component of data for attenuation correction by continuing measurement of the relative angle between a gamma ray source for attenuation correction and detector pair out of a plurality of detectors thereby determining whether or not, at a given moment, the gamma ray source is present within the zone of measurement allocated for a specific detector pair which has detected coincidence and, when the determination ascertains that the source is not present in the aforementioned zone of measurement, avoiding measurement of coincidence or preventing data on coincidence from being stored in a memory.
