Tomography reconstruction from projections data is an inverse problem widely used in the medical imaging field. With sufficiently large number of projections over the required angle, the FBP (filtered backprojection) algorithms allow fast and accurate reconstructions. However in the cases of limited views (lose dose imaging) and/or limited angle (specific constrains of the setup), the data available for inversion are not complete, the problem becomes more ill-conditioned, and the results show significant artifacts. In these situations, an alternative approach of reconstruction, based on a discrete model of the problem, consists in using an iterative algorithm or a statistical modelisation of the problem to compute an estimate of the unknown...
