Known-component metal artifact reduction (KC-MAR) for cone-beam CT.

Conclusions. The KC-MAR algorithm combines knowledge of surgical instrumentation with 3D image reconstruction in a manner that overcomes potential pitfalls of segmentation. The approach is compatible with FBP - thereby maintaining simplicity in a manner that is consistent with surgical workflow - or more sophisticated model-based reconstruction methods that could further improve image quality and/or help reduce radiation dose.&#13.
