Example Clip Artifact Volume Reconstructions in Relation to Cortical Surface Models. Basal and mid-sagittal views of each patient's cortical surface model are shown shaded by curvature (top row) and as a point cloud (second row). Superimposed on the point could displays to aide artifact visualization are the reconstructed clip artifact volumes colored according to MR sequence in descending order by clip volume as percentage of brain volume (T2 = green, T1 = yellow, DWI = blue, EPI = red). These artifact volumes are 0.27%, 0.56%, 1.70%, and 4.67% respectively for Patient A (two columns on left), and 0.48%, 1.04%, 3.62%, and 4.74% respectively for Patient B (two columns on right).
