Ultrasound trainer with internal optical tracking
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.
1. An ultrasound trainer, comprising:
a) a chamber defining an orifice;
b) a shaft insertable into the orifice of the chamber, the shaft having a proximal end, a distal end opposite the proximal end, a flexible tip at the distal end, and a control knob to bend the flexible tip;
c) a marker positioned on the shaft at the distal end;
d) a camera positioned to view inside the chamber towards the orifice;
e) a processor operatively connected to the camera for processing a position and an orientation of the shaft based on the marker;
f) a motion limiter connected to the chamber at the orifice;
g) a filler material inside the chamber;
h) a light source to illuminate the chamber, wherein the chamber mimics a body.
