The advent and development of new imaging techniques and image-guidance have had a major impact on surgical practice. These techniques attempt to allow the clinician to not only visualize what is currently visible, but also what is beneath the surface, or function. These systems are often based on tracking systems coupled with registration and visualization technologies. The accuracy and precision of the tracking systems, thus is critical in the overall accuracy and precision of the image-guidance system. In this work the accuracy and precision of an Aurora tracking system is assessed, using the technique specified in " novel technique for analysis of accuracy of magnetic tracking systems used in image guided surgery." This analysis yielded a demonstration that accuracy is dependent on distance from the tracker's field generator, and had an RMS value of 1.48 mm. The error has the similar characteristics and values as the previous work, thus validating this method for tracker analysis.
