AbstractAbstract
[en] A prototype gamma ray camera system has been constructed based on high purity germanium detectors fabricated with orthogonal strip electrodes. Position sensitivity is obtained by connecting each contact strip on the detector to a charge dividing resistor network. The camera requires only three amplifier channels to measure the energy and location of gamma ray events. Excellent energy and spatial resolution have been achieved by cooling the resistor networks to 770K and by proper selection of noise filtering parameters in the pulse shaping amplifier circuitry. Theoretical and experimental results obtained in the investigation of the charge splitting camera concept are presented. These results indicate that it is possible to construct a high resolution germanium camera system which has sufficient field of view and sensitivity for routine use in nuclear medicine
