Localization of intracranial electrodes is critical for invasive epilepsy evaluations and to confirm or not confirm the epileptic zone hypothesis. Various methods exist using various open-source and commercial software. Here is one method using some latest updates to the Brainstorm software.
- Pre-implantation T1 without contrast 1mm 3D volume scan
- Post-implantation CT scan without contrast 1mm 3D volume scan
Assuming you are already familiar with Brainstorm and have already created anatomy files using Freesurfer:
Choose Freesurfer folder
Change file type to Freesurfer
Convert CT to .nii.gz first with MRIcroGL (drag and drop)
