In a recent preliminary experiment, a test phantom was imaged using Diffraction Enhanced Imaging (DEI). DEI is a synchrotronbased radiographic imaging technique which uses a single energy of X-rays and the fine angular acceptance of Bragg diffraction to separate out the components of the X-ray beam
A Shannon reconstruction of the values of sampled \(n\)-dimensional functions can be performed by a moving window technique (MWSR) with no truncation errors, provided that the window is regarded as a complete sampling interval. Each reconstructed point of the function is obtained by convoluting the
