Commonly used iterative techniques for image reconstruction from projections include ART (Algebraic Reconstruction Technique) and SIRT (Simultaneous Iterative Reconstruction Technique). It has been shown that these are the two extremes of a general family of block-iterative image reconstruction techniques. Here we show that the initial performance of these commonly used extremes can be bested by other members of the family.
