    Reconstruction algorithms in x-ray tomography provide
    a user with a set of images. For many scientific problems
    these images should be segmented. Ring artifacts are the most
    noticeable artifacts which do not allow a scientist to achieve
    acceptable segmentation especially in case of noisy input data.
    Several ring artifact suppression methods based on theory of
    ill-posed problems exist. In this letter the basic ring artifact
    suppression algorithm is rewritten as a 1D filter, so it does
    not require separate data processing and can be combined with
    standard filtering used in filtered backprojection algorithms.
