It constists in implanting stimulating electrodes in the brain tissue to electrically stimulate a specific deep part of the brain.The efficiency of the treatment relies on the placement accuracy of the electrodes. The target coordinates and the trajectory to reach the target are determined by the surgeon during the preoperative planning, relying on preoperative patient data.However, a series of brain shifts takes place during and after the procedure. This alters the accuracy of the planning, increasing risks of hemorrhage due to vital structures motion, sides effects due to a gap between the target and the electrode extremity.My work is to develop tools for this surgery based on numerical biomechanical simulations. I developed a brain shift model used in different contexts: computation of the post-operative electrode curvature, brain-shift aware pre-operative planning which can be coupled with an automatic computation of the electrodes trajectory and a physics-based intra-operative registration.https://www.sofa-framework.org/applications/marketplace/deep-brain-stimulation/ Show less
