Partially slotted crystals for a high-resolution gamma-camera based on a position sensitive photomultiplier

Abstract

Partially slotted crystals have been designed and constructed and have been used to evaluate the performance with respect to the spatial resolution of a gamma-camera based on a position-sensitive photomultiplier. It is shown that the resolution obtained with such a crystal is only slightly worse than the one obtained with a fully pixelized one whose cost, however, is much higher. (c) 2005 Elsevier B.V.
