Abstract
A high-efficiency detector system developed especially for medical imaging has three speciall cut Ge(Li) coaxial detectors (total volume 249 cm3). At 122 keV, the peak efficiency is 93% of that of a 7.6 Ã 7.6 cm NaI (T1) detector. Degradation of the paralleled energy resolution is avoided and resolution is improved by 35% over that of conventional output-summing techniques by gating the detector outputs. In effect this multiplexes them to a single line output.
