An open-source software for neurosurgical trajectory planning, visualization, and postoperative assessment

What is trajectoryGuide?

trajectoryGuide provides the capability to plan surgical trajectories within 3D Slicer, an open-source medical imaging software. trajectoryGuide contains modules that span the three phases of neurosurgical trajectory planning:

Preoperative features

  • automatic stereotactic frame detection (supported frames: Leksell, BRW, and CRW)
  • co-registration of MRI and CT scans (incorporated registration algorithms: ANTS, FSL, or NiftyReg)
  • trajectory planning providing coordinates in anatomical and stereotactic space (including arc, ring angles)

Preoperative planning.

Perioperative features

  • update final electrode position based on intra-operative testing
  • display microelectrode recordings (MER) within the patients MRI space

Perioperative planning.

Postoperative features

  • electrode localization (using post-op imaging)
  • visualize stimulation settings as volume of activated tissue
  • view data within a template space (provided spaces: MNI152NLin2009bAsym, MNI152NLin2009cAsym, and PD25)

Volume of activated tissue.
