[en] Deep Brain Stimulation is a neurosurgery procedure
consisting in implanting an electrode in a deep structure
of the brain. This intervention requires a preoperative planning
phase, with a millimetric accuracy, in which surgeons decide the
best placement of the electrode depending on a set of surgical
rules. However, brain tissues may deform during the surgery
because of the brain shift phenomenon, leading the electrode to
mistake the target, or moreover to damage a vital anatomical
structure. In this paper, we present a patient-specific automatic
planning approach for DBS procedures which accounts for
brain deformation. Our approach couples an optimization
algorithm with FEM based brain shift simulation. The system
was tested successfully on a patient-specific 3D model, and
was compared to a planning without considering brain shift.
The obtained results point out the importance of performing
planning in dynamic conditions.
