ENERGY RESOLVED COMPUTER TOMOGRAPHY

摘要

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.
