Figure 12From: Data-guide for brain deformation in surgery: comparison of linear and nonlinear models Two groups of resulting points of each model and the corresponding real result from the intra-operative images. The points estimated by the nonlinear model (green points) are the nearest points to the intra-operative points (yellow points) while those estimated by the linear mechanical model (pink points) are superior to those estimated by the linear elastic model.Back to article page
