Summary:Interpolation of the momentum transfer prior to the filtered backprojection reconstruction in computer tomography baggage inspection or medical applications may not result in best image quality or minimal computational cost. According to an exemplary embodiment of the invention, a non-linear energy binning of an energy-resolved single-row detector is provided, which automatically leads to a Cartesian q-sampling on a parallel rebinned detector. This may avoid the q interpolation prior to the filtered back projection reconstruction, resulting in improved spatial resolution, reduction of computational effort and improved image quality.
