PURPOSE Metal artifact reduction (MAR) is a challenging problem in computed tomography (CT) imaging. A popular class of MAR methods replace sinogram measurements that are corrupted by metal with artificial data, typically generated from some combination of interpolation along with other heuristics. While these "projection completion" approaches are successful in eliminating severe artifacts, secondary artifacts may be introduced by the artificial data. In this paper, we propose an approach…

A hybrid metal artifact reduction algorithm for x-ray CT.
The proposed metal artifact reduction method has the lowest RMSE in regions of both soft tissue and bone tissue among the corrected images and is ranked as the best method for evaluation, by radiologists.
A pragmatic approach to metal artifact reduction in CT: merging of metal artifact reduced images
Merging combines the advantages of two fundamentally different approaches to artifact reduction and can improve the quality of images that are affected by metal artifacts.
Normalized metal artifact reduction (NMAR) in computed tomography.
PURPOSE While modern clinical CT scanners under normal circumstances produce high quality images, severe artifacts degrade the image quality and the diagnostic value if metal prostheses or other
Frequency split metal artifact reduction (FSMAR) in computed tomography.
FSMAR ensures sharp edges and a preservation of anatomical details which is in many cases better than after applying an inpainting-based MAR method only, and yields images without the usual blurring close to implants.
Metal artifact reduction in CT using tissue-class modeling and adaptive prefiltering.
High-density objects such as metal prostheses, surgical clips, or dental fillings generate streak-like artifacts in computed tomography images. We present a novel method for metal artifact reduction
A novel forward projection-based metal artifact reduction method for flat-detector computed tomography
This study presents a novel method for reducing metal artifacts in flat-detector computed tomography reconstructed volumetric images by inserting discarded information into the original rawdata using a three-step correction procedure and working directly with each detector element.
A fully 3D approach for metal artifact reduction in computed tomography.
It is recommended to include as much spatial information into the recomputation step as possible by increasing the dimension of the NFFT, and the resulting image quality can be enhanced considerably.
Spurious structures created by interpolation-based CT metal artifact reduction
It is concluded that a restoration scheme without additionally information is not sufficient for a successful metal artifacts reduction method, and the application of a more sophisticated artifact reduction method based on a segmentation of a preliminary reconstructed image decreases the number of newly introduced artifacts to a large degree.
Efficient Metal Artifact Reduction Method Based on Improved Total Variation Regularization
A method for metal artifact reduction that combines modified compressed sensing reconstruction and the sinogram inpainting method is proposed and results show that streaks are eliminated and shadows are significantly reduced.
Metal artifact reduction in computed tomography using local models in an image block-iterative scheme.
Reconstruction schemes including the sequential update of the patches result in images with less streak artifacts compared to a regular reconstruction, which can be achieved by using complex models only locally without losing image quality.
