Paper Abstract

The Mojette transform is a discrete and exact Radon transform, based on the discrete geometry of the projection and reconstruction lattice. The specific sampling scheme of the Mojette transform results in theoretical exact image reconstruction. In this paper, we compare the reconstructions obtained with the Mojette transform to the ones obtained with several usual projection/backprojection digitized Radon transform. These experiments validate and demonstrate the performance of the Mojette transform sampling over classical implementations based on continuous space.
