Abstract

A training system to teach use of an ultrasound probe, the training system having a chamber defining an orifice, a shaft insertable into the orifice of the chamber, a marker positioned on the shaft at a distal end, a camera positioned to view the marker when inserted inside the chamber, and a processor operatively connected to the camera for processing a position and an orientation of the shaft based on the marker. The system provides a method for visualizing movement of the shaft from inside the chamber.
