Abstract
A gamma fusion computing method based on gamma probe parameters includes: acquiring measurement values of two gamma probes in one continuous rotation period, and utilizing a mean value and a variance of the measurement values in the one rotation period as an evaluation reference value of each gamma probe; determining whether the gamma probes are abnormal, if the two gamma probes are both normal, utilizing the weight values to perform weight fusion on the measured values measured by two gamma probes, and if there is a gamma probe that is abnormal, then multiplying the average of the measured values of the normal gamma probe in the rotation period by 2 as a gamma output value for output.
