Abstract: The purpose of this paper is to address the design of a system to track surgical instrument’s movement during an operation. Motion tracking of surgical instruments is one of the most interesting methods to survey the data needed for medical robotics, computer-aided surgery, skills assessment and training progress applications. Over the wide range of tracking technologies, low frequency ultrasound was selected to meet the system’s requirements. Factors that bring about measurement inaccuracies are analysed and taken into account when developing the system. Furthermore, a localization algorithm that calculates three-dimensional position using one-dimensional distances and overriding signal blockage is presented. Moreover, experimental results of a resectoscope mock up motion tracking are shown.
