Abstract
In an effort to overcome limitations of conventional collimation for imaging high energy (>300 keV) single photon emitters, studies were conducted to measure the performance parameters of an electronically collimated gamma camera for imaging a Cs-137 source at 662 keV. In addition to theoretical computations, coincident counts from a point, line and disk source of Cs-137 were acquired with a prototype system to investigate the resolution and sensitivity characteristics. The results show that, unlike conventional collimation, the performance of an electronically collimated system improves with energy, thereby enabling efficient imaging at high energies.
