Abstract :
A three-dimensional source reconstruction technique has been investigated for a new ring Compton scatter camera based on electronic collimation. The method uses each first detector element to find directions to the source locations, and then intersects these directions from all detector elements to find the intensity and three-dimensional location of the source. The results for a simulated 150-keV point source located on the camera axis and a line source perpendicular to the camera axis are presented
