Orthogonal IR system for instrumental tracking in minimally invasive spine procedures for training using wiimote technology

Abstract

In this paper we present a system for track the movements of the training instrumental in 3D space, using two infrared Cameras from two Nintendo Wii Remotes in order to evaluate the progress surgeons during the learning phase for making incisions and placement of screws in the spine throw minimally invasive procedures. The cameras are positioned orthogonally, and they detect the position of IR markers that are placed in the training instrumental.
