Abstract

Ring artifacts are among of the most common artifacts in cone beam computed tomography (CT). High resolution images are often disturbed by these artifacts. In this paper, a ring artifacts reduction method is proposed based on cone beam projection images. CUDA technique is used to accelerate the method. The performance of the proposed algorithm is evaluated using real cone beam CT images. Experiment results demonstrate that the proposed technique effectively eliminates the ring artifactsand has superior calculation speed using CUDA than the calculation speed of CPU.
