Summary
This study introduces a 3D visualization system using geometric pattern projection for real-time surgical navigation. The system accurately tracks soft tissue deformation, enabling precise superimposition of preoperative organ models during surgery.
Area of Science:
- Medical Imaging
- Surgical Navigation
- Biomedical Engineering
Background:
- Intra-operative navigation aids surgical understanding but traditional methods struggle with soft tissue deformation.
- Current position sensors (magnetic, optical) are insufficient for dynamic soft tissue tracking.
Purpose of the Study:
- To develop and evaluate a 3D visualization system for real-time surgical field deformation monitoring.
- To enable accurate registration and superimposition of preoperative models onto dynamic soft tissues.
Main Methods:
- Developed a 3D visualization system employing geometric pattern projection.
- Utilized time-sequential surface deformation data for registration.
- Performed animal experiments for validation.
Main Results:
- Successfully registered preoperative 3D organ models using updated surface deformation data.
- Achieved accurate superimposition of internal organ structures onto the surgical field video image.
Conclusions:
- The developed system effectively visualizes surgical field deformation in real-time.
- This technology is crucial for accurate navigation and enhanced understanding when operating on soft tissues.
