Navigation to improve outcome of epilepsy surgery

The successful neurosurgical treatment of epilepsy depends on complete removal of the part of the brain that gives rise to epileptic seizures, and in avoiding damage to brain areas and pathways critical for functions such as vision, language, sensation and motor control. Achieving these goals requires accurate 3D planning of the surgical approach and resection and real time feedback during the course of surgery. This project builds upon our EpiNAV platform to visualize brain structures that need to be removed to cure epilepsy, and those that need to be spared, in order to avoid adverse effects. This anatomical guidance will be displayed to the surgeon via a neurosurgical navigation interface so that brain tissue removal is optimised, in terms of maximising the chances of remission of the epilepsy and avoiding complications such a loss of part of the field of vision and of language abilities.
