This paper addresses the problem of real-time guidance of a robot operating on an open brain as the brain undergoes a deformation (brain shift) due to the loss of cerebrospinal fluid (CSF) and the reduction of intracranial pressure. Commonly, neurosurgical navigation loses its accuracy due to the deformation, as it is based on static pre-operative brain images. We aim to improve this accuracy by providing a real-time “image” of the deforming brain, which is computed from tracking features on the exposed cortex and models the physical behavior of brain tissue.
