Abstract

PURPOSE: Epilepsy surgery is a potential curative treatment for people with focal epilepsy. Intraoperative electrocorticogram (ioECoG) recordings from the brain guide neurosurgeons during resection. Accurate localization of epileptic activity and thus the ioECoG grids is critical for successful outcomes. We aim to develop and evaluate the feasibility of a novel method for localizing small, deformable objects using augmented reality (AR) head-mounted displays (HMDs) and artificial intelligence (AI). AR HMDs combine cameras and patient overlay visualization in a compact design.
