title = "2-dimensional detector decoding study on BGO arrays with quadrant sharing photomultipliers",
abstract = "This is a theoretical and experimental study of the positron camera detector design using quadrant sharing of phototubes and optically cross-coupled BGO scintillation crystals. This study computes statistically the maximum number of BGO crystals which can be coupled to a photomultiplier with this design based on the number of photoelectrons generated and the optical efficiency of the crystal-phototube combination. Statistically, a 10×10 BGO array can be coupled to a single square phototube and be clearly decoded. The optimal light distribution to the decoding phototubes to achieve the highest decoding density is found and then used to guide the development of an experimental detector module. Experimentally, this study demonstrates that 8×8 arrays of 3.2×3.2 mm BGO crystals can be coupled to large, less expensive 26×26mm square-single-phototubes and be fully delineated. The reconstructed image resolution with this less expensive detector implementation is estimated to be 3.0mm transaxially and 2.4mm axially.",
