Summary
Virtual Interactive Presence (VIP) enables real-time surgical telecollaboration by sharing visual fields between remote surgeons. This technology is feasible for long-distance surgical training and expert support.
Area of Science:
- Surgical Technology
- Medical Informatics
- Remote Collaboration
Background:
- Surgeon shortages necessitate innovative technologies to extend surgical capabilities.
- Virtual Interactive Presence (VIP) is a novel platform for real-time surgical telecollaboration.
Purpose of the Study:
- To demonstrate the feasibility of VIP for long-distance telecollaboration during cadaveric dissection.
- To evaluate the performance of the VIP system in a simulated surgical environment.
Main Methods:
- VIP utilizes connected workstations with video capture and displays for shared visual fields.
- Commercial teleconferencing facilitates worldwide point-to-point communication.
- A cadaveric suboccipital craniotomy and pineal region dissection was performed using VIP.
Main Results:
- Participants successfully interacted visually and verbally for anatomical identification and surgical guidance.
- Mean compositing delay was 760 ± 606 msec, with adequate image resolution for complex anatomy.
- Subjective evaluations indicated successful task completion and system performance.
Conclusions:
- VIP is a feasible platform for real-time, long-distance surgical telecollaboration.
- Optimization of delay, resolution, scaling, and registration is needed but achievable with current technology.
- VIP has potential applications in surgical training, remote proctoring, and expert support for underserved areas.
