Abstract: Provided are a system and method for combining detector signals. In one exemplary embodiment, the system includes the detector, a plurality of ASICs where each ASIC may receive an electric signal from the detector and generate a position signal and an energy signal based on the received electric signal, a combiner that may combine a position signal output from a first ASIC and a position signal output from a second ASIC to generate a combined position signal, and combine an energy signal output from the first ASIC and an energy signal output from the second ASIC to generate a combined energy signal, and an analog-to-digital converter that may receive the combined position signal and the combined energy signal and generate digitized image data for the first ASIC and the second ASIC based thereon.

Abstract: A system and method for compensating signal delay across a solid state photomultiplier. The method including determining respective arrival times of signals from a plurality of microcells of the photomultiplier, calculating a signal transit time delay difference between the respective arrival times for individual signals, correlating the individual transit time delay differences to an amount of respective signal propagation compensation for respective microcells of the photomultiplier, and introducing the respective signal propagation compensation into circuitry of the respective microcells. The method also includes at least one of adjusting a response shape of a photodiode within each of the plurality of microcells, adjusting operating parameters of a one-shot pulse circuit within the microcells, and modifying circuit design values of each microcells during fabrication of the photomultiplier.
