Paper Abstract

Computer studies of the three-dimensional imaging characteristics of a new single gamma emission tomography system have been conducted. In this system collimation is performed electronically by recording a sequential interaction of the gamma radiation with two detectors. A considerable gain in sensitivity is expected over a conventionally collimated system. Radiation is scattered from the first detector onto the second detector, and events are recorded in coincidence. The activity is thereby localized on conical surfaces inside the object to be imaged. A novel two-step iterative algorithm nas been developed to reconstruct the three-dimensional emission images for this system. Results of computer simulation studies are presented.
