Abstract

We report on the development of an evaluation detector module built for our miniPET -3 small animal PET scanner. The module is based on an LySO scintillation matrix exactly matching that used in miniPET-II (so that the performance of the two PET scanners is easier to compare), followed by a Silicon Photomultiplier (SiPM) matrix array. The front-end electronics is designed to be modular, so that different readout concepts can be evaluated and prototype-tested. The readout electronics is based on a system-on-module with Spartan-6 FPGA and Gigabit Ethernet connectivity. Different SiPM readout concepts were tested using the module, and based on the evaluation results one was selected for implementation and testing.
