Figure 1

Separation of patients by semi-automatic investigations of the connected neighborhoods for each artifact. (A) Patient from GroupINNER where the artifact is fully enclosed by the anatomical surface. (B) Patient from GroupOUTER where the artifact breaches the anatomical surface and is artificially connected to the background. From left to right: transaxial view, coronal view and sagittal view of MR-ACDIXON attenuation maps.
