Breast tomosynthesis reconstructions require a wide range of design choices to be made in order to yield consistently good results. Since algebraic reconstruction, specifically the SART algorithm, has given excellent results in CT and is being actively considered for commercial use in tomosynthesis, we in this study systematically vary a number of key imaging parameters and assess the performance of the SART algorithm under these variations. The phantoms used are basic ellipsoids in 2D (yielding analytical projections), and an MR-derived breast phantom in 3D.
