Algorithm of the image processing. (1) Processing of the T1-weighted MRI image using freesurfer(extraction of the pial surface and leptomeningeal surface, segmentation of brain structures); (2) Coregistration of the postimplant CT scan with processed MRI using iELVis coregistration tool; (3) Labeling of electrodes on coregistrated CT using Bioimage Suite 3. (4) Postimplantation brain shift correction using iELVis Yang, Wang et.al. tool. (5) Creating images of electrode locations. (
