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