Owing to the high dynamic range and resolution of image plates, digitization of the direct-beam profile as well as of two-dimensional small-angle X-ray scattering patterns gives data with enough accuracy to allow desmearing of two-dimensional patterns after corrections of geometrical distortions. A radial conversion of the images is used to compress the images and to isolate a small area of interest. The results obtained by the Wiener filtering method and the iterative method of Van Cittert on simulated patterns are compared.
