    Area of Science:

    • Medical Simulation
    • Virtual Reality in Medicine
    • Interventional Radiology Training

    Background:

    • Image-guided percutaneous needle puncture is complex due to 3D anatomy visualization challenges.
    • Existing virtual reality (VR) simulators often lack structured learning frameworks.
    • Need for effective training methods to improve procedural efficiency and skill acquisition.

    Purpose of the Study:

    • To introduce PunctVR, a VR system using scaffolding for image-guided needle puncture training.
    • To evaluate the impact of integrated 3D visualization and scaffolding on learning outcomes.
    • To assess the effectiveness of PunctVR in enhancing procedural efficiency.

    Main Methods:

    • Developed PunctVR with phased subgoal workflow and instructional guidance scaffolding.
    • Conducted a between-subject experiment with 16 physicians comparing multiplanar reconstruction (MPR) view with MPR + 3D visualization.
    • Assessed performance in an assessment-only test mode after training.

    Main Results:

    • All trainees showed significant performance improvement after PunctVR training.
    • Training with integrated 3D visualization led to greater reduction in puncture time.
    • Enhanced learning scaffolding accelerated skill acquisition and retention.

    Conclusions:

    • PunctVR effectively enhances procedural efficiency in simulated needle puncture training.
    • Integrated 3D visualization in VR training improves skill acquisition for image-guided interventions.
    • Scaffolding principles in VR simulation accelerate learning and retention of complex procedures.
