Localization of dense intracranial electrode arrays using magnetic resonance imaging

► Intracranial electrode arrays are localized on MRI despite susceptibility artifacts. ► Electrodes directly visualized on subject's gyral anatomy and MNI standard brain. ► High spatial accuracy is validated using intra-operative photographs. ► Method is characterized by minimal user input and short processing time. ► Accurate localization allows full use of spatial resolution of intracranial EEG.
