Learning-Based Patch-Wise Metal Segmentation with Consistency Check
Tristan M. Gottschalk, Andreas Maier, Florian Kordon +1
Metal implants that are inserted into the patient's body during trauma interventions cause heavy artifacts in 3D X-ray acquisitions. Metal Artifact Reduction (MAR) methods, whose f…
