Abstract	Monte Carlo techniques have been used to study and optimize a two-dimensional detector array system for high-resolution positron emission tomography (PET) that consists of an 8*4 matrix of BGO crystals coupled to four photomultipliers. This allows dense packing of small scintillation crystals and their optical coupling to a smaller number of photomultiplier tubes. The design included optimizing the optical crosstalk between detectors in terms of detection efficiency and resolution. Different crystal identification schemes were also investigated. Some preliminary results including the positioning accuracy and the detection efficiency of the module are presented. The average correct identification was estimated to be 83.6% and the average detection efficiency was estimated to be 76.1%.<>
