Gamma camera for emission tomography and method for adaptive event position estimation
First Claim
1. A method for estimating a line of flight of coincident photons in an emission tomography system, the system including an array of gamma radiation detectors and a line of flight estimator, the method comprising taking responses resulting from detection of a pair of photons by a pair of opposite detectors, consisting of a first detector and a second detector, in the array that are on opposite sides of the line of flight, estimating directly the line of flight by the line of flight estimator, taking into account responses from both detectors.
