                         of reconstruction techniques for emission computed tomography of 
                         the PET type (Positron Emission Tomography), based on filtering 
                         the Poisson noise of the one dimensional projections, followed by 
                         the use of conventional fast algorithms, like 
                         convolution-backprojection. The purpose of this work is to refine 
                         the one dimensional projections estimation techniques previously 
                         proposed, by taking into account the correlation between points in 
                         the non-noisy one dimensional projections, both on the filtering 
                         and to the parameter estimation procedures.",
