Abstract

Several methods have been formulated for reconstructing the density (image) from a set of its projections. For a review of methods, see Gordon and Herman and Budinger and Gullberg. Some of the algebraic methods are known to optimize certain properties of the reconstructions. For instance, the least-squares solution gives an estimate of the image density such that the discrepancy between the given projection data and the projection data corresponding to the reconstructed picture is a minimum.
