Digital implementation of position estimation for the modular scintillation camera is presented. The modular camera system comprises an array of small, mechanically and electronically independent, all-digital scintillation cameras. This paper addresses how to best determine the event position given the photomultiplier-tube signals. Two Bayesian estimators are investigated, namely, maximum-likelihood and minimum-mean-square-error estimators. Both estimators performed similarly. The more important aspect of the estimation problem was found to be the shape of the detector responses as a function of position.
