New training methods based on mixed reality for interventional ultrasound: Design and validation

Area of Science:

• Medical Simulation
• Ultrasound Imaging
• Surgical Training

Background:

• Traditional ultrasound-guided biopsy training relies on 'learning by doing,' potentially risking patient safety during a novice's learning curve.
• There is a need for safe, effective training methods that improve skills like 3D perception and hand-eye coordination for ultrasound interventions.

Purpose of the Study:

• To develop and validate a hybrid simulator for ultrasound-guided biopsy training.
• To assess the simulator's effectiveness in improving 3D perception and hand-eye coordination for novice learners.

Main Methods:

• Development of a hybrid simulator integrating mixed reality visualization for ultrasound-guided biopsy.
• Demonstration of face, content, and construct validity for the developed simulator.
• Utilizing mixed reality to aid in planning probe positioning and needle trajectory.

Main Results:

• The hybrid simulator successfully demonstrated face, content, and construct validity.
• The system provides support for acquiring 3D perception and hand-eye coordination skills.
• Mixed reality visualization facilitates accurate planning of probe and needle placement.

Conclusions:

• A hybrid simulator offers a safe and effective alternative to traditional training methods for ultrasound-guided biopsy.
• This technology can significantly enhance the acquisition of crucial psychomotor skills for novice practitioners.
• The validated simulator represents a valuable tool for improving the quality and safety of medical education in ultrasound interventions.
