Abstract: International audienceIn this paper, we develop an exact, reversible and scale change rotation in the Mojette projection space. The whole process is performed using 1D fast operators and has the advantage to be consistent with standard tomographic geometry

International audienceIn this paper, we develop a global iterative algorithm for tomographic reconstructions from Mojette projections. Since Spline-Mojette projections are obtained by convolving Dirac-Mojette values with a specific uniform projection kernel, we decorrelate iterative reconstructions from projection model and provide a global scheme available for all Mojette models. We refer iterative algorithms to their Radon based counterparts and propose a comparative study from several Mojette acquisitions
