Summary
Autostereoscopic 3D visualization (ASV) may enhance depth perception in minimally invasive surgery (MIS). This study found single-viewer ASV feasible in clinical settings, analyzing surgical workflows and display usage for design requirements.
Area of Science:
- Medical Visualization
- Surgical Technology
- Human-Computer Interaction
Background:
- Minimally invasive surgery (MIS) often lacks depth perception.
- Autostereoscopic 3D visualization (ASV) offers a potential solution without special eyewear.
- Clinical feasibility of single-viewer ASV in MIS remains undemonstrated.
Purpose of the Study:
- Analyze surgical workflows and display usage in MIS.
- Assess the potential for integrating single-viewer ASV into MIS.
- Identify key design requirements for ASV, including eye-tracking and workspace.
Main Methods:
- Investigated two gynecologic interventions.
- Developed a vision-based tracking system with depth cameras and ArUco markers.
- Simultaneously tracked operating staff and display poses.
Main Results:
- Recorded 20 surgeries with 4 clinicians using 3 displays.
- Users maintained a mean display distance of 1900 mm (range 1200-2300 mm).
- Surgeons predominantly viewed a single display (99%) from consistent locations.
Conclusions:
- Single-viewer ASV is feasible for MIS based on observed surgical workflows.
- Defined viewing positions and display focus support ASV integration.
- Further research should focus on eye-tracking and 3D workspace design for ASV.
