Abstract
A radiation detection device includes a gamma detector configured to receive a stream of non-random and random photon events and generate corresponding list-mode data, and a computing device in communication with the gamma detector configured to receive the list-mode data, determine, by applying at least one statistical timing analysis method to a segment of the list-mode data, data associated with the non-random photon events, predict, based on the data, a next non-random time window, and reject photon events that have arrival times, at the gamma detector, in the predicted non-random time window.
