Area of Science:

  • Medical Technology
  • Surgical Navigation
  • Augmented Reality

Background:

  • Presents a DIY method for an affordable augmented reality heads-up display (AR-HUD).
  • Utilizes commercially available components for surgeon accessibility.
  • Aims to display intraoperative images for educational and research purposes.

Purpose of the Study:

  • To develop and evaluate a cost-effective AR-HUD system for surgical applications.
  • To integrate real-time intraoperative imaging into a surgeon's field of view.
  • To assess the feasibility and clinical impact of a DIY AR-HUD.

Main Methods:

  • Connected Moverio BT 35-E smart glasses to operating room imaging (fluoroscopy, 3D navigation).
  • Employed a high-definition multimedia interface (HDMI) converter for video transmission.
  • Integrated an HDMI transmitter-receiver for wireless AR-HUD functionality.

Main Results:

  • Successfully implemented the AR-HUD system in 3 instrumented spinal fusion surgeries.
  • Projected fluoroscopy images directly onto the surgical field.
  • Observed a clinically insignificant transmission delay of 40-100 ms, maintaining focus and minimizing interruptions.

Conclusions:

  • An affordable AR-HUD for real-time surgical information display is easily constructible and testable.
  • Wearable technology advancements allow for component upgrades to enhance functionality.
  • Surgeons can optimize AR systems through in-operating room clinical testing.
