چکیده انگلیسی
This work describes and characterizes the detector module of a novel positron/single photon emission (PET/SPECT) scanner for small animals. This detector consists of a YAP/LSO phoswich, a photomultiplier and acquisition front-end, and will be used as building block of a low-cost hybrid tomograph. The front-end processes data sampled at a fixed frequency, where a state-of-the-art programmable device estimates scintillation pulse parameters by means of digital algorithms. Finally, the estimated properties of the proposed detector module are used to model a rotating four-head scanner. The performance of the proposed PET/SPECT scanner is estimated and first results are promising in both modalities, deserving further research and optimization.
