Patent ID: 8735836

Claim:
An interconnect system for a positron emission tomography (PET) block detector, the interconnect system comprising: a plurality of summers at the PET block detector, the plurality of summers configured to generate first and second position signals and an energy signal from at least four photo multiplier tube (PMT) signals from a respective at least four PMTs; a detector circuit configured for event discrimination and time stamping from the first and second position signals and the energy signal output from the summers; a gain circuit at the PET block detector, the gain circuit configured to separately set a gain of each PMT of the PET block detector in response to gain control signals; a controller configured to control the gain circuit with the gain control signals; and a cable connected between the PET block detector and the detector circuit, the cable comprising at least four twisted pairs of wires for the first and second position signals, the energy signal, and the gain signals, the cable being a single cable for transmitting the first and second position signals from the PET block detector to the detector circuit and transmitting the gain control signals from the detector circuit to the PET block detector.
