Abstract: Neurosurgery interventions involve complex tracking systems because a tissuedeformation takesplace. The neuronavigation system relies only on preoperativeimages. In order to overcome the soft tissue deformations and guarantee theaccuracy of the navigation a biomechanical model can be used during surgery tosimulate the deformation of the brain. Therefore, a mesh generation for anoptimal real-time Finite Element Model FEM becomes crucial. In this work wepresent different alternatives from a meshgeneration point of view that wereevaluated to optimize the process in terms of elements quantity and quality aswell as constraints of a intraoperative application and patient specific data.
