This study introduces an automated trajectory planner for Stereo-Electroencephalography (SEEG) procedures. The planner optimizes electrode placement, ensuring safety by avoiding critical brain structures and blood vessels for epilepsy treatment.

Area of Science:

  • Neurosurgery
  • Medical Imaging
  • Computational Neuroscience

Background:

  • Stereo-Electroencephalography (SEEG) is crucial for localizing the epileptogenic zone in drug-resistant epilepsy.
  • Current SEEG planning relies on manual trajectory definition, which can be time-consuming and may not always optimize safety parameters.

Purpose of the Study:

  • To develop and evaluate an automatic multitrajectory planner for SEEG procedures.
  • To optimize electrode trajectories based on distance from vessels and guiding screw angle while sparing critical brain structures.

Main Methods:

  • An automatic multitrajectory planner was developed to compute optimal SEEG electrode paths.
  • The planner considers distance from vessels, guiding screw angle, and avoids specific brain structures (e.g., lateral ventricles, brain stem).
