Summary
Augmented reality (AR) navigation enhances stereotactic biopsy safety for deep-seated lesions. This trans-visible navigator (TVN) system allows surgeons to visualize 3D models, improving trajectory planning and biopsy accuracy without complications.
Area of Science:
- Neurosurgery
- Medical Imaging
- Surgical Navigation
Background:
- Frame-based and frameless stereotaxy are standard for deep-seated lesion biopsies but have limitations.
- Existing stereotactic biopsy methods present challenges in accurately navigating complex anatomy.
- Disadvantages in current techniques necessitate innovative approaches for improved safety and efficacy.
Observation:
- A novel trans-visible navigator (TVN) system utilizing augmented reality (AR) was applied to frame-based stereotactic biopsy.
- The TVN system projects 3D anatomical models onto the surgical field via a tablet computer.
- Surgeons could visualize virtual structures overlaid on the real surgical environment.
Findings:
- The AR-based TVN system facilitated clear trajectory confirmation, avoiding critical anatomical structures.
- Accurate identification of the target lesion's location was achieved using the navigation system.
- All five cases of deep-seated lesion biopsy resulted in satisfactory histopathological diagnoses without complications.
Implications:
- Augmented reality application in stereotactic biopsy is feasible and demonstrates potential for enhanced surgical safety.
- The TVN system may offer a valuable tool for improving precision in neurosurgical biopsies.
- This approach could reduce the risk of complications associated with deep-seated lesion biopsies.
