摘要：

We have developed a detector block composed by a monolithic LYSO scintillator coupled to a custom made 12 x 12 SiPMs array. The design is mainly focused to applications such as Positron Emission Tomography. The readout electronics is based on 3 identical and scalable Application Specific Integrated Circuits (ASlC). We have determined the main performance of the detector block namely spatial, energy, and time resolution but also the system capability to determine the photon depth of interaction, for different crystal surface treatments. Intrinsic detector spatial resolution values as good as 1.7 mm FVVHM and energies of 15% for black painted crystals were measured. (C) 2014 Elsevier B.V. All rights reserved
