We created a navigation system for endoscopic procedures, extracting and overlaying 3D information onto live video. This system achieves high accuracy, improving surgical guidance with real-time 3D data.

Area of Science:

  • Medical Imaging
  • Surgical Navigation
  • Endoscopy

Background:

  • Endoscopic interventions require precise navigation.
  • Real-time 3D visualization aids surgical accuracy.
  • Existing systems may lack sufficient precision or integration.

Purpose of the Study:

  • To develop and validate a navigation support system for endoscopic interventions.
  • To enable extraction and superimposition of 3D information onto live endoscopic video.
  • To achieve high accuracy in 3D data acquisition during procedures.

Main Methods:

  • Coupling an endoscope with a position measurement system and calibrated video camera.
  • Implementing algorithms for radial distortion correction of wide-angle endoscopic lenses.

  • Utilizing tracking on live endoscopic video sequences for 3D depth data acquisition from multiple views.

    • Main Results:

    • Successful correction of radial distortions in endoscopic lenses.
    • Achieved an overall system accuracy of approximately 0.7 mm.
    • Demonstrated accurate 3D depth data acquisition using multi-view tracking on live video.

    Conclusions:

    • The developed navigation support system enhances 3D information visualization during endoscopy.
    • The system offers high accuracy, crucial for precise endoscopic interventions.
    • This technology has the potential to improve surgical outcomes and safety.
