This project explored how to integrate smartphone inertial tracking technology and virtual 3D anatomical models in creating a biopsy simulator for ultrasound- guided liver biopsy. The prototype simulator allowed the virtual ultrasound probe and biopsy needle to be tracked by the smartphone’s built-in inertial tracking system and ultimately allowed the trainee to control the movement of the virtual probe and needle in a manner similar to a real biopsy technique. It offers a promising low-cost option for simulating medical procedures with motion tracking functionality while maintaining realism to a certain degree.
