A three-dimensional maximum-likelihood reconstruction method is presented for a prototype electronically collimated single-photon-emission system. The electronically collimated system uses a gamma camera fronted by an array of germanium detectors to

A heuristic procedure to identify binding constraints in linear programming (LP) problems is based upon an examination of the orientation of the constraining closed half spaces with respect to the orientation of the objective function. The constraint

An electronic collimation system for SPECT imaging has been designed to provide improved detection efficiency over a mechanical collimator. A maximum likelihood estimator (MLE) is derived for this prototype electronically collimated system. The data
