  • Abstract
    We report on experiments on combining iterative weighted filtered backprojection with nonlinear regularization. The resulting methods allow for contrast dependent resolution. In combination with improved geometrical modeling of the acquisition process, they have the potential to improve high contrast resolution while preserving low contrast image properties.
