Abstract	Information about the /spl gamma/ depth of interaction (DOI) in the crystal can help to improve the resolution uniformity in positron emission tomography cameras by reducing the blurring due to the parallax error. The parallax error is particularly severe for tomographs with small detector-to-detector distance, which is by itself a desirable feature, since it maximizes the detection solid angle and thus sensitivity. In this study we have developed simulations to determine the effect of a particular DOI correction method on resolution for some tomograph and crystal geometries. For specific configurations examined DOI correction was found to improve the resolution uniformity up to 37%.
