ABSTRACT:
A method for predicting PMT failure in a gamma camera by generating historical data for each PMT in a gamma camera indicating high voltage gain values at which each PMT causes autotune failure. The historical data is analyzed to predict PMT failure accurately thereby allowing PMT maintenance prior to failure actually occurring.
