Area of Science:

  • Neurosurgery
  • Medical Imaging
  • Software Development

Background:

  • Frame-based stereotaxy is crucial for deep-brain electrode placement.
  • Existing commercial systems have limitations in workflow efficiency and planning.
  • A need for specialized software was identified during a clinical study for treatment-resistant depression.

Purpose of the Study:

  • To develop and validate Tactics, a novel software for simulating and planning frame-based stereotactic electrode placement.
  • To improve the efficiency and accuracy of deep-brain electrode implantation procedures.
  • To provide an open-source solution for the neurosurgical community.

Main Methods:

  • Development of Tactics software with a simplified workflow for electrode placement simulation.
  • Implementation of automated frame localization and user-extensible electrode specification import.
  • Systematic validation using a purpose-built imaging phantom and comparison against gold-standard techniques.

Main Results:

  • Tactics offers immediate in-context visualization of electrode contacts and cortical entry sites.
  • The software facilitates rapid planning and placement of multiple electrodes, outperforming commercial systems.
  • Tactics has been successfully used in over 50 surgical cases for planning >300 depth-electrode targets and trajectories.

Conclusions:

  • Tactics provides a significantly simpler and more efficient workflow for frame-based stereotactic procedures.
  • The software enhances accuracy and planning capabilities, particularly for complex electrode placements like invasive electroencephalography.
  • As an open-source tool, Tactics is available for community use and further development.
