Abstract
In this work we present a Mesh Warping technique for the construction of patient-specific Finite Element Method models from
patient MRI images, and demonstrate how simulated surgical loading can be applied to these models. We compare the results
of this simulation with observed deformation during surgery, and show that our model matches well with the observed degree
of deformation.
