Abstract
A positron emission tomography (PET) photosensor output circuit configured to be operably coupled to a PET photosensor system is provided that includes a plurality of regional circuit portions and a summing portion. Each regional circuit portion is configured to be operably coupled to a corresponding photosensor system region and includes an input portion, a first branch, and a second branch. The first branch includes a delay unit and a switch. The second branch includes a sensor unit configured to place the switch in a closed position when a signal received via the input portion satisfies a threshold and to place the switch in an open position when the signal received via the input portion does not satisfy the threshold. The summing portion is configured to receive corresponding regional circuit outputs from the regional circuit portions, and to combine the regional circuit outputs to provide a summed output.
