This neurosurgery navigation system enhances surgical precision by overlaying real-time 3D models onto live endoscopic and microscopic views. It guides surgeons with sub-2mm accuracy, improving safety and effectiveness during complex procedures.

Area of Science:

Neurosurgery
Medical Imaging
Surgical Navigation

Background:

Neurosurgical procedures demand high precision.
Real-time anatomical visualization is crucial for complex surgeries.
Current navigation systems may have limitations in integration and accuracy.

Purpose of the Study:

To develop and evaluate a novel navigation system for neurosurgery.
To integrate real-time 3D anatomical models with live surgical video feeds.
To enhance surgeon's focus and accuracy during procedures.

Main Methods:

A navigation system was developed for surgical microscopes and endoscopes.
Wireframe models were generated from CT/MRI scans.
Non-contact sensors tracked patient position and orientation in real-time.
