Intracranial Electrode Visualization in Invasive Pre-surgical Evaluation for Epilepsy.

Invasive intracranial electroencephalography (EEG) studies help identify the epileptogenic focus and assess if the identified zone overlies eloquent cortex by means of cortical stimulation. Proper interpretation and use of the intracranial recording/stimulation studies requires an effective display of multimodal information. We developed a software system which can combine the patient's segmented brain, post-implanting MRI/CT images, intracranial EEG findings and results from cortical stimulations into one integrated environment of three-dimensional visualization. This platform can efficiently facilitate the epilepsy pre-surgical evaluation and epilepsy surgery planning.
