Popis:	We describe the development of a scintillator-coated charge coupled device (CCD) based camera for imaging small volumes of radionuclide uptake in tissues. The high resolution gamma imager (HRGI) is a collimated, scintillator-coated, low cost, high performance imager using low noise CCDs. The HRGI operates in photon counting mode using a peltier cooler to achieve an operating temperature of 0/spl deg/C. We have measured the spatial resolution and efficiency of a prototype CCD from e2v Technologies Ltd coated with a 500/spl mu/m thick Gadox (Gd2O2S(Tb)) layer using 59.5 keV radiation from a /sup 241/Am source and 140 keV gamma-rays from a /sup 99m/Tc source. We also describe our first images using /sup 99m/Tc phantoms.
