Patent ID: 7554089

Claim:
A method for localizing an optical emission, comprising: identifying a first readout channel of a first pixellated photodetector based on an impact of first group of one or more photons on the first pixellated photodetector, wherein the first group of photons are emitted by a scintillator unit of a scintillator array and wherein the first readout channel corresponds to a column of one or more pixels of the first pixellated photodetector; identifying a second readout channel of a second pixellated photodetector based on an impact of a second group of one or more photons on the second pixellated photodetector, wherein the second group of photons are emitted by the scintillator unit and wherein the second readout channel corresponds to a row of one or more pixels of the second pixellated photodetector; and identifying the scintillator unit based on the first readout channel and the second readout channel.
