Validation of Mojette reconstruction from Radon acquisitions

Two new methods to perform interpolation mapping from Radon sinogram to Mojette domain are presented. Reconstructions are made from both spaces using FBP and SART algorithms. Assessment of the methods is made both from Shepp-Logan phantom and actual data and demonstrate the efficiency of the proposed algorithms.
