Abstract
A device that will allow a neurosurgeon to track his or her position on presurgical images during the course of an operation is presented. The device consists of a six-degree-of-freedom articulated arm with high-precision joint position sensors. Each of the optical encoders provides 16 bits of angular information, giving a maximum endpoint uncertainty of less than 1 mm. The end point position is calculated by use of the forward kinematic equations
