Summary
This study presents a new method using a genetic algorithm for safer keyhole neurosurgery trajectories. The approach reduces surgical risks and significantly speeds up the trajectory search process.
Area of Science:
- Neurosurgery
- Medical Imaging
- Computational Biology
Background:
- Preoperative assessment is crucial for minimizing complications in keyhole neurosurgery.
- Identifying the safest surgical trajectory is a key challenge.
Purpose of the Study:
- To introduce a novel, semiautomated methodology for preoperative risk assessment.
- To optimize the search for the safest trajectory in keyhole neurosurgery.
Main Methods:
- A semiautomated risk assessment methodology was developed.
- A generic genetic algorithm was employed for the safest trajectory search.
- Risk maps considering voxel proximity to critical structures were utilized.
Main Results:
- Candidate trajectories were identified for two surgical procedures.
- The proposed method yielded trajectories that were 5% shorter.
- Trajectories demonstrated a 4.7% greater distance from blood vessels.
Conclusions:
- The genetic algorithm significantly accelerates the trajectory search, reducing time by 99.9%.
- The developed method enhances safety by optimizing trajectory selection.
- This approach offers a more efficient and safer preoperative planning tool for neurosurgeons.
