    Abstract: A method and apparatus for estimating a position distribution of radiation emission The method and apparatus include obtaining a time difference between radiations detected by a pair of detectors, and creating a probability distribution function (PDF) indicating the probability of where the radiations actually were or may have been emitted. The PDF may be created based on the time difference and timing resolutions of the pair of detectors.
