In this paper the authors discuss causes for image deterioration in the maximum likelihood estimator (MLE) method of tomographic image reconstruction that we initiated with the publication of a stopping rule for that iterative process. They introduce the concept of a feasible image, which is a result of a reconstruction that, if it were a radiation field, could have generated the initial projection data by the Poisson process that governs radioactive decay. From the premise that the result of a reconstruction should be feasible, they examine the shape and characteristics of the region of feasibility in projection space.
