                         transmission tomography. The algorithms are based on the formalism 
                         of POCS (Projection onto Convex Sets): ART (Algebraic 
                         Reconstruction Technique), SIRT (Simultaneous Iterative 
                         Reconstruction Technique), sequential POCS and parallel POCS. We 
                         found that the use of adequate a priori knowledge about the 
                         solutions, expressed by convex sets restrictions, particularly in 
                         the case of the last algorithm, is an efficient way to reduce the 
                         variations on the solutions due to the ill-conditioning of the 
                         reconstruction problem, not only due to the noise in the 
                         projections, but also due to limited view reconstruction.",
