Polychromatic X-ray tomography: direct quantitative phase reconstruction Academic Article uri icon


  • We describe a direct quantitative phase reconstruction approach using an X-ray laboratory-based source. Using a single phase-contrast image from each tomographic projection we show that it is possible to modify the filter term in a filtered back projection reconstruction to take account of the broad spectrum from a laboratory source. The accessibility of conventional X-ray laboratory sources makes this method very useful for quantitative phase imaging of homogeneous and weakly absorbing objects.
