evaluation of surgical treatment of epilepsy patients often requires
implantation of subdural grid electrodes on the cortex. The exact locations
of implanted electrodes are essential to evaluate cortical lesions related to
seizure onsets and delineate eloquent brain areas. The process requires
registration via multi-modality image warping and correction of
post-craniotomy brain deformation. The loss of CSF fluid the presence of
epidural or subdural hematoma from open craniotomy cause brain shifts. This
work presents an mapping of electrodes from post-implant CT data to pre- or
post surgery MRI by intermodality image warping to determine accurate
positions involved in electrocortical stimulation.
