A ring artifact suppression algorithm based on a priori information
Sofya Titarenko, Valeriy Titarenko, Albrecht Kyrieleis, and Philip J. Withers
In this letter, ring artifacts in two-dimensional (2D) tomographic slices are considered. For a parallel beam geometry we propose an interactive algorithm, which removes the artifacts while preserving fine image details. The algorithm comprises two stages and is based on a priori information about t ... [Appl. Phys. Lett. 95, 071113 (2009)] published Fri Aug 21, 2009.
