    Area of Science:

    • Medical device tracking
    • Surgical simulation
    • Image-guided interventions

    Background:

    • Accurate tracking of medical devices like ultrasound probes is crucial for surgical planning, training, and image guidance.
    • Existing tracking systems vary in cost and precision, necessitating comparative evaluations for specific applications.
    • Integration with medical image processing platforms (e.g., 3D Slicer, MevisLab) is essential for practical use.

    Purpose of the Study:

    • To comparatively evaluate the performance of low-cost SteamVR Tracking and Opti-Track systems for medical device tracking.
    • To assess the suitability of these systems for ultrasound probe tracking in surgical simulation.
    • To investigate tracking accuracy under non-laboratory conditions, including reflections and occlusions.

    Main Methods:

    • Comparative evaluation of Swept Angle Laser Tracking (SALT) system SteamVR Tracking and Opti-Track.
    • Use of a Universal Robotics UR5 industrial robot for controlled tracking error assessment.
    • Testing under non-laboratory conditions simulating real-world challenges like reflections and occlusions.
    • Integration with 3D Slicer and MeVisLab via PLUS Toolkit and OpenIGTLink protocol.

    Main Results:

    • Both SteamVR Tracking and Opti-Track demonstrated potential for accurate medical device tracking.
    • Tracking accuracy was evaluated under challenging, non-laboratory conditions.
    • Successful data communication was established with 3D Slicer and MeVisLab for simulation purposes.

    Conclusions:

    • SteamVR Tracking and Opti-Track are viable options for precise medical device tracking, particularly for ultrasound probe simulation.
    • The systems show promise for integration into surgical planning and training workflows.
    • Further investigation into tracking accuracy under diverse real-world conditions is warranted.
