A principled approach to polychromatic X-RAY tomography for metal artifact reduction

Résumé

We put forward a principled variational approach to computed tomography, in the presence of metals. It is based on the inversion of a forward model accounting both for the polychromatic nature of X-rays, and for the Poisson statistics ruling the photon counting process. A fast and flexible numerical solving framework is proposed, which handles a variety of regularization terms. The efficiency of the proposed method is demonstrated on simulations.
