Summary
We developed an automated method for deep brain stimulation (DBS) trajectory planning, significantly reducing planning time and identifying new surgical constraints. This approach enhances image-guided neurosurgery by optimizing trajectories while avoiding critical brain structures.
Area of Science:
- Neurosurgery
- Medical Imaging
- Computational Neuroscience
Background:
- Deep brain stimulation (DBS) is a crucial treatment for neurological disorders.
- Preoperative trajectory planning is complex, time-consuming, and prone to human error.
- Current methods may not fully account for all critical anatomical structures and surgical constraints.
Purpose of the Study:
- To develop an automated method for optimizing DBS trajectories.
- To integrate multi-modal MRI data for precise surgical planning.
- To reduce the risk of complications by avoiding critical brain structures.
Main Methods:
- Utilized multi-modal MRI analysis (T1w, SWI, TOF-MRA).
- Developed a framework for automated trajectory planning to DBS targets (subthalamic nuclei, globus pallidus interna).
- Incorporated avoidance of critical brain structures into the planning algorithm.
Main Results:
- The automated method significantly reduced planning time (less than 1/10th of manual planning).
- The framework successfully aggregated numerous surgical constraints.
- Thousands of trajectories were analyzed efficiently.
Conclusions:
- The proposed automated method is effective for preoperative DBS trajectory planning.
- The system accelerates surgical planning and enhances safety by considering critical structures.
- Qualitative evaluation revealed potential new constraints for improved neurosurgical decision-making.
