Inter-crystal scatter could lead to loss of data or mispositioning of scintillation events, which is of a particular interest in imaging detectors used in Positron Emission Tomography. Because it is difficult to measure the scatter and to quantify its effects, a Monte Carlo simulation has been proposed to study inter-detector scattering and how it affects the spatial resolution of a BGO block. The MCNP4C2 code was used for simulations of the 8 x 4 crystal BGO block detector, the silicon layer covering its face and a line source. Accurate simulations were made for the grooves in the BGO block detector (light guides), which vary according to the location of the crystal within the block. In transaxial plane the cuts are symmetrical about the central cut and have a depths of 23.1, 24.4, 27.7 and 30mm respectively. In the axial plane there are three cuts, tow outer cuts are 30mm deep and the central cut is 23.1mm deep. The line spread function (LSF) was simulated for each column and row at a time by scanning the line source axially and transaxially across the collimated fall of the BGO block detector, which shielded all other columns and rows. Comparison was made between simulated inter-crystal scattering for neighbouring crystals
