Abstract
Studies have been performed in order to optimize the collimator and the crystal of a γ-camera based on a position sensitive photomultiplier with respect its efficiency, its spatial resolution and its cost. Several parallel hole collimators of different thicknesses have been tested and compared to each other. The homogeneous crystals’ performance has also been compared to that of a pixelized CsI(Tl) crystal. It is shown that though the spatial resolution of the homogeneous crystals is not as good as that of the pixelized one it is still reasonable and it could probably be improved by the choice of a better position reconstruction algorithm.
