Fig. 6.10 The predicted deformation fields overlaid on an axial slice of pre-operative image (six
examples). An arrow represents a 2D vector consisting of the x (R-L) and y (A-P) components
of displacement at a voxel centre. Green arrows show the deformation field predicted by the
biomechanical model. Red arrows show the deformation field calculated by the BSpline algorithm.
The number on each image denotes a particular neurosurgery case. (Modified from [93])
