HDRR, HDBSPLINE, HDPBNRR, and HDA−PBNRR are alignment errors after Rigid Registration (RR), B-Spline, PBNRR, and A-PBNRR registration, respectively. HD are in mm. The number in the parenthesis denotes the number of adaptive iterations for A-PBNRR. BS, Brain Shift; PR, Partial Resection; TR, Total Resection; STR, Supra Total Resection.
