Neurosurgery

Based on an intra-operative registration method, we developed a simulation of a DBS (Deep Brain Stimulation) surgery which can help the surgeon to locate anatomical structures for a safer and a more efficient treatment. The method relies on the biomechanical model of brain shift we developed during the last years. Because some parameters of the model are unknown, we propose to estimate them with an optimization process. The cost function evaluates the distance between the model and the segmentation of pneumocephalus, the only indicator of brain shift visible on an intra-operative CT scan. In 2015, an article about the rest shape of the brain was accepted [19] .
