Abstract
A system for determining a three-dimensional position of a tip of a testing tool in an anatomic training model can be used for injection training. The system can include first and second cameras positioned in the anatomic training model. The first and second cameras can each detect an area of light emitted from the tip of the testing tool. The system can also include a processing unit configured to trace the emitted light away from a location of a centroid of the area of emitted light in the first camera and a location of a centroid of the area of emitted light in the second camera respectively, and calculate a three-dimensional position of the distal tip of the testing tool based on the locations of the centroids. The calculation can take into account refraction of the emitted light through an innermost layer of the training model.
