The measured, predicted, and corrected brain shift results (mean ± SD with maximum in parenthesis) for all 16 cases. With respect to location (L-left, R-right, T-temporal, F-frontal, P-parietal). With respect to basis, ‘C’ indicates that corresponding points drove the correction, while ‘Wcp’ indicates sparse corresponding points were used to directionally weight additional closest point distances were employed
