  • Minerals Free Fulltext Spectral Tomography For 3d

    This paper demonstrates the potential of a new 3D imaging technique, Spectral Computed Tomography sp-CT, to identify heavy elements inside materials, which can be used to classify mineral phases. The method combines the total X-ray transmission measured by a normal polychromatic X-ray detector, and the transmitted X-ray energy spectrum measured by a detector that discriminates between X-rays ...
