Robust maximum-likelihood position estimation in scintillation cameras
The authors derive a robust ML (maximum-likelihood) position estimator that accounts for the statistical uncertainty in LSF (light-speed function) measurements. The form of the robust estimator diminishes contributions from the tails of the LSF, where the relative measurement errors are the largest. To evaluate the estimator, the authors simulated one dimension of a position-sensitive detector similar to those in the SPRINT II system.<<ETX>>
