Résumé :

In this work, we present the application of algorithms based on algebraic methods, ray tomography image reconstruction X. So DROP algorithms with quadratic regularization (orthogonal projections Relaxes diagonal), conjugate gradient and Kaczmarz will be implemented and applied to real images obtained by an X-ray tomography, a comparative study was made in order to examine the reconstruction algorithms results
