Project Description
Deep brain stimulation is a neurosurgical treatment involving the permanent implantation of electrodes in the brain, to stimulate a specific deep structure.
Electrical stimulation of some brain structures treats symptoms of motor or affective neurological disorders. The success of the operation relies on the electrode placement precision, for which the goal is to maximize the therapeutic outcomes, and minimize the adverse effects.
To do that, a preoperative planning step determine the target coordinates to stimulate, as well as the electrode trajectory to reach it, thanks to a combination of medical images of the patient and numerical tools.
However, intraoperative brain deformation, called brain shift, might invalidate the planning.
This project relied on a biomechanical model of brain shift which comprises a mechanical model for deformation, as well as a model of cerebrospinal fluid leak.
We presented a preoperative tool, based on our model, in order to provide the surgeon with an information on the deformation risks, that he could use to select a safe trajectory for the patient, even in the case of brain shift.
Moreover, we proposed an intraoperative registration method based on our biomechanical model, in order to compute the new location of anatomical structures.
Finally, thanks to a model of insertion of the electrode and its interaction with brain tissue, we reproduced the operating protocol in order to compute the electrode curvature due to brain shift.
