Abstract
A CZT Compton Camera (CCC) is being built using two three-dimensional (3-D) position-sensitive CZT detectors. Expected system performance was analyzed by analytical and Monte Carlo approaches. Based on the measurement of dete ctor energy and position resolution, the expected angular resolution is sim ilar to 3 degrees and similar to 2 degrees for a +/- 30 degrees FOV for 511 keV and 1 MeV gamma -rays, respectively. The intrinsic efficiency for a po int source 10 cm from the first detector surface ranges from 1.5 x 10(-4) t o 8.8 x 10(-6) for 500 keV-3 MeV. (C) 2001 Elsevier Science B.V. All rights reserved.
