Abstract
A method for detecting potential faults in a cooling system that cools a detector electronic assembly (DEA) of a positron emission tomography (PET) imaging system having a plurality of PET detector rings each including a plurality of PET detectors having an associated DEA. The method includes verifying continuity of coolant lines in a coolant flow path of a DEA and calculating a flow rate through a coolant flow path of a DEA. Selected circuit board temperature sensors are used to detect temperature values that serve as surrogates for temperature change of a coolant. Further, the selected temperature sensors are located on hardware that is replicated on different points or locations on the flow path such that the temperature sensors have similar performance characteristics and are of like kind.
