Localization of electrodes in 3D view. (A) An example of localized of depth electrodes in a simple scenario, consisting of eight depth electrode arrays (Patient 22). (B) Example of localized of depth and grid electrodes in a complex scenario, formed by two grids and three depth electrode arrays entering through the gap between these two (Patient 5). In the last scenario, the selection of voxels in a 3D view is extremely simpler than the selection in 2D views. Additionally, the 3D view of localized coordinates on a rendered semitransparent brain helps to easily understand the relationship between electrodes and brain anatomy.
