Electrode localization process of the toolbox.A) Pre-implant MRI images from a single subject. B) The brain reconstruction results using the MRI images from A. The brain segmentation results are generated after the brain reconstruction. C) The smoothed brain surface generated after B. This process is implemented automatically by executing Freesurfer functions from the toolbox. D) Post-implant CT images are aligned to the MRI images by running the coregistration function from the toolbox. E) Location and profiles of all implanted electrodes are extracted from the coregistered CT images. F) Electrode labelling process after electrode extraction. Coordinates of all the electrodes are computed and transformed into the space where the individual brain (B,C) is located after this step in the toolbox. G/H) Original reconstructed brain surface and electrodes before brain shift correction. I/J) Reconstructed brain surface and electrodes after brain shift correction. Subject information from Subject 28 are used here for illustration.
