TL;DR: This treatise reports on how CT-sytems could be transformed from non-exact to exact reconstruction methods by means of iterative post-processing, and expects much faster convergence.
Abstract: Most contemporary CT-sytems employ non-exact methods. This treatise reports on how these methods could be transformed from non-exact to exact reconstruction methods by means of iterative post-processing. Compared to traditional algebraic reconstruction (ART) we expect much faster convergence (in theory quadratic), due to a much improved first guess and the fact that each iteration includes the same non-exact analytical reconstruction step as the first guess.
