Overview

Electrode localization is a critical step for getting spatial information of iEEG and DBS electrodes. YAEL (Your Advanced Electrode Localizer) provides a fully integrated pipeline that takes in raw DICOM or NIfTI images and outputs the electrode coordinates and atlas labels. The pipeline is divided into two parts:

  • Input: T1 pre-operative MRI and post-surgery CT

  • Step 1: Imaging preprocess

  • Step 2: Interactive 3D electrode localization

  • Output: electrode coordinate table and RAVE 3D viewer

Prerequisites

Step 1: Imaging Preprocess

The imaging preprocess module in YAEL contains the following two parts. If you would like to substitute any part (or even the entire module) with your existing pipelines, see ‘Alternative Preprocess’ (TBD) below.

  • T1 image preprocess
  • CT-MR co-registration

Here is a video tutorial using NIfTI T1 and CT as input:

Step 2: Interactive 3D electrode localization

Here is an introductory video of using YAEL interactive 3D viewer for electrode localization.
