Area of Science:

  • Medical Imaging and Visualization
  • Virtual Reality in Medicine
  • Computational Geometry

Background:

  • Complex virtual medical objects from CT/MRI scans can be maze-like, causing disorientation during VR sessions.
  • Users performing non-invasive diagnostics require guided pathways for effective navigation.
  • Existing methods may struggle with the complexity of anatomical structures.

Purpose of the Study:

  • To introduce a disembodied autonomous actor for navigation support in virtual medical environments.
  • To enable guided fly-throughs within complex, reconstructed anatomical models.
  • To enhance diagnostic capabilities in virtual endoscopy applications.

Main Methods:

  • A synthetic vision-based actor was developed to find collision-free paths.

  • The actor voxelizes virtual environments and uses a backtracking search algorithm.
  • Automata and rules govern the actor's navigation behavior.

    • Main Results:

    • The path search method successfully navigated various 3D tubular anatomical structures (aortas, colons, brain blood vessels).
    • Paths were found within practical time constraints, even for complex surface models.
    • The actor demonstrated effective navigation in environments with loops and impasses.

    Conclusions:

    • The proposed autonomous actor is a valuable tool for virtual endoscopic diagnostics.
    • This method can assist in screening activities within virtual medical environments.
    • It offers a promising solution for navigating complex patient-specific anatomical models.
