BACKGROUND: Accurate localization and visualization of subdural electrodes implanted for intracranial electroencephalography in cases of medically refractory epilepsy remains a challenging clinical problem. OBJECTIVE: We introduce a technique for creating accurate 3-dimensional (3D) brain models with electrode overlays, ideal for resective surgical planning. METHODS: Our procedure uses postimplantation magnetic resonance imaging (MRI) and computed tomographic (CT) imaging to create 3D models of…

3D visualization of subdural electrode shift as measured at craniotomy reopening
Rapid and accurate anatomical localization of implanted subdural electrodes in a virtual reality environment.
TLDR
The results indicate that the 3D virtual reality simulation software used in the series is a useful tool for rapid and precise localization of subdural electrodes implanted for invasive electroencephalography (EEG) recordings.
Localization of dense intracranial electrode arrays using magnetic resonance imaging
Patient-specific solution of the electrocorticography forward problem in deforming brain
TLDR
A biomechanicsbased image warping procedure using preoperative MRI for tissue classification and postoperative CT for locating implanted electrodes to perform non-rigid registration of the preoperative image data to the postoperative configuration is presented and suggests that rapid and accurate solution of the forward problem in a deformed brain for a given patient is achievable.
Patient-specific solution of the electrocorticography forward problem using biomechanics-based image registration
TLDR
A biomechanics-based image warping procedure using preoperative MRI for tissue classification and postoperative CT for locating implanted electrodes to perform non-rigid registration of the preoperative image data to the postoperative configuration and suggests that significant improvements in source localization accuracy may be realized by the application of the proposed modeling methodology.
Investigation of subdural electrode displacement in invasive epilepsy surgery workup using neuronavigation and intraoperative MRI
TLDR
Comparison of pre-explantation and post-implantation iopMRI scans with CT/MRI data using the volume-rendering technique resulted in an accurate placement of electrodes in one patient with a considerable electrode dislocation, and the surgical approach and extent was changed due to the detected electrode shift.
Three-Dimensional Accuracy of ECOG Strip Electrode Localization Using Coregistration of Preoperative MRI and Intraoperative Fluoroscopy
TLDR
Localization of temporarily inserted subdural strip electrode coordinates can be accomplished using preoperative MRI and intraoperative fluoroscopy.
iElectrodes: A Comprehensive Open-Source Toolbox for Depth and Subdural Grid Electrode Localization
TLDR
iElectrodes is presented, an open-source toolbox that provides robust and accurate semi-automatic localization of both subdural grids and depth electrodes and provided additional advantages in terms of robustness (even with severe perioperative cerebral distortions), speed (less than half the operator time compared to expert manual localization), simplicity, utility across multiple electrode types (surface anddepth electrodes) and all brain regions.
Localizing and tracking electrodes using stereovision in epilepsy cases
TLDR
An intraoperative stereovision system is used to visualize and localize the cortical surface as well as electrodes, record three-dimensional locations of the electrodes in MR space at the time of implantation and resection, respectively, and quantify the raw displacements with respect to the skull.
Integrated analysis of anatomical and electrophysiological human intracranial data
TLDR
This protocol describes how to computationally process, integrate, visualize, and analyze anatomical and functional data obtained during intracranial electroencephalography (iEEG) of the human brain.

Retrospective Fusion of Radiographic and MR Data for Localization of Subdural Electrodes
TLDR
In experiments with a phantom and patients, implanted electrodes were imaged with multiplanar skull radiographs and the position of each electrode with respect to a metabolic lesion was displayed by mapping preimplantation PET data onto the same brain model.

TLDR
3D MRI with 3D surface reconstruction proved superior to 2D imaging and CT for the assessment of EEG electrode localization and a more precise delineation of the localization of the EEG electrodes and the simultaneous display of the adjacent brain structures.

TLDR
Intraoperative visualization of the electrodes with fluoroscopy combined with neuronavigation during positioning through a bur hole gives the neurosurgeon the ability to control the real position of the electrode over the gyri during the procedure.

TLDR
The coregistration of digital photographs of the brain cortex with the results of 3D MRI data sets is possible, allowing for identification of anatomic details underlying the subdural grid electrodes and enhances the orientation of the surgeon.

TLDR
Because of extensive streak artifacts, CT showed only gross complications, such as herniation and grid displacement by extraaxial collections, allowing superior evaluation of subdural EEG grid placement and associated complications.

TLDR
Six different co-registration algorithms including surface-oriented, mutual information-based and landmark-based methods were compared and a brain surface oriented method was judged visually to be the best, had a low intra- and inter-observer variability, and lasted approximately 15 minutes.
