摘要：

We report the development of a gamma-ray imager using a 5 mm thick, 50 mm diameter Gd2SiO5 (GSO) crystal coupled to a 2D position-sensitive photomultiplier tube (Hamamatsu R2486). A considerable improvement in the position linearity and resolution was achieved upon placing around the GSO scintillator a glass ring which has the same thickness and the same index of refraction as the GSO crystal. A position resolution of 2.2 mm FWHM was obtained at 511 keV.
