摘要：
Techniques for imaging radioactive emission in a target volume include collecting from each of multiple detectors in a Compton camera, within a coincidence time interval, location and deposited energy from an interaction associated with each high energy particle source event in a target volume, for N source events. A cone of possible locations for each source event is determined based on the locations and deposited energies collected. A SOE algorithm is initiated by selecting a random location on the cone and generating a histogram that indicates, a count of the selected locations that occur inside each voxel of the target volume. N solution locations for the N source events are determined after L iterations by updating the selected location on a corresponding cone based at least in part on values of the counts in the histogram excluding the current source event. A solution is presented on a display device.
