Abstract:
1. In a Positron Emission Tomography (PET) system comprising a plurality of detectors, a method for determining the position of a radioactive source, the method comprising: detecting a scatter coincidence event, the event characterized by a full-energy photon detected at a first detector and partial-energy photon detected at a second detector of a PET camera; and measuring the time difference via time of flight between the time of arrival of the partial energy photon at the second detector and the time of arrival of the full energy photon at the first detector; measuring the energy of the partial-energy photon; determining a scattering point as a function of at least: determining the position of a radioactive PET source along a pseudo Line of Response (LOR) between the scatter point and the first detector as a function of at least:
