Paper Abstract

Spectral CT research and development has recently become a hot topic in industry and in academia. Different approaches have been developed for spectral CT imaging. As a result of the capability to generate monochromatic-energy images, beam hardening artifacts have been largely reduced. However, X-ray scatter is still present, and the associated scatter artifact can still be present in the base material images. This paper proposes an approach for scatter artifact reduction for dual-energy CT. Phantoms as well as clinical data have been evaluated to demonstrate the effectiveness of this approach.
