                         reconstruction method is a hybrid estimation theoretic-POCS 
                         (Projection Onto Convex Sets) method performed by first estimating 
                         the noisy projections using Anscombe Transformation, Discrete 
                         Wavelet Transform and pointwise Wiener filter and subsequently 
                         reconstructing the images through a parallel POCS method. The use 
                         of a previous filtering of the projections imposes a tighter 
                         restriction on the observation of the POCS method, allowing a 
                         better reconstruction, with a very little increase in 
                         computational cost.",
