Area of Science:

  • Medical Simulation
  • Virtual Reality
  • Medical Imaging

Background:

  • Bronchoscopy planning requires accurate visualization of the bronchial tree.
  • Current manual or fully automatic tracking methods for bronchial navigation have limitations.
  • Patient safety is paramount, necessitating non-invasive planning tools.

Purpose of the Study:

  • To develop an interactive virtual environment for bronchoscopy simulation.
  • To enhance the safety and efficiency of surgical planning.
  • To provide natural and interactive navigation of the bronchial tree.

Main Methods:

  • Development of a virtual environment with a 3D pen input device.
  • Implementation of a semi-automatic vessel tracking technique (Intelligent Path Tracker).

    • The Intelligent Path Tracker offers both automation and user control for bronchial navigation.
    • IsoRegion Leaping and distributed rendering achieve interactive frame rates (>10 Hz) for 256x256x256 lung volume data.

    Conclusions:

    • The developed virtual bronchoscopy system provides a safe and effective platform for surgical planning.
    • The novel tracking and rendering techniques enable real-time, interactive visualization of the bronchial tree.
    • This technology has the potential to improve pre-surgical assessment and reduce patient risk.
