Energy-dispersive coherent scatter computed tomography

Abstract

We present a reconstructive x-ray imaging technique that yields the spatially resolved coherent scatter form factor of macroscopic objects. High spectral resolution is obtained by the energy and angle analyses of coherently scattered photons. In comparison with transmission x-ray computed tomography structural information about the materials under investigation is obtained. The combination of the attenuation contrast and the scatter contrast obtained with this technique can be applied, e.g., in medical imaging or baggage inspection.
