In the past 10 years, many inverse problem approaches have been proposed for tomographic reconstruction. The Reconstruction ToolKit (RTK) is an open-source library for fast circular cone-beam CT, which provides efficient implementations of some of these "iterative" methods. In order to reach clinically acceptable reconstruction times, RTK combines GPU and multi-core implementations with algorithmic accelerations: ordered subsets, preconditioning, and empirical design of regularized reconstruction methods.
