AUTOMATIC DEPTH ELECTRODE LOCALIZATION IN INTRACRANIAL SPACE

Abstract

Localization and precise targeting of depth electrodes in the regions of the human brain is critical for accurate clinical diagnoses and treatment as well as for epileptical source localization and studies of in-vivo electrical propagation. By using magnetic resonance imaging (MRI) combined with computed tomography (CT), the authors present a method based on image processing and object recognition that improves electrode localization in different brain anatomies and matter. This method permits the quantified localization of electrode placements in cortex and white matter, and gives the precise position of each electrode, allowing a more detailed study of intra-cranial electrical stimulation, propagation and properties of conductivity related to the brain. Such methods can be extended to depth-scalp signal analysis using simultaneously registered SEEG and EEG measurements.
