Abstract
We study the asymptotic behavior of some iterative methods used in image reconstruction from projections. These methods combine in each step a major iteration of a standard series expansion algorithm like ART followed by the application of a smoothing matrix. We prove convergence for a whole family of these methods when the matrix is symmetric, and we give counterexamples for other cases.

A set of optimization criteria and a number of iterative reconstruction algorithms are stated, together with theorems on the convergence of the algorithms to optimum images and the efficacy of the algorithm is compared to that of the convolution method.

These methods are based on the discretization of the image domain prior to any mathematical analysis and thus are rooted in a completely different branch of mathematics than the transform methods which are discussed in this issue.

In this tutorial paper, the inversion formula for the case of two-dimensional (2-D) reconstruction from line integrals is manipulated into a number of different forms, each of which may be discretized to obtain different algorithms for reconstruction from sampled data.

By associating systematically to this problem an equivalent one posed in ann-fold cartesian product space, by decomposition of the latter both a splitting of operators and a desintegration of constraints for the former are obtained.
