95-, 75-, 50- and 25-percentile Hausdorff distance between surface of the ventricles obtained by registration (i.e. warping using the predicted deformation field) of the preoperative segmentation and intraoperative surface of the ventricles determined from the intraoperative image segmentation. The 95-percentile Hausdorff distance (numbers in bold font) was used as the registration error measure. Case 6 was analysed in our previous studies (Joldes et al. 2009a; Joldes et al. 2009b; Wittek et al., 2007; Wittek et al., 2009). The results are presented to one decimal place as we previously determined (Wittek et al., 2007) that this is approximately the accuracy of computations using finite element algorithms of the type applied in this study (i.e. explicit integration in the time domain and elements with linear shape functions).
