Abstract

With the increased use and development of image-guided surgical applications, there is a need for methods of analysis of the accuracy and precision of the components which compose these systems. One primary component of an image-guided surgery system is the position tracking system which allows for the localization of a tool within the surgical field and provides information which is translated back to the images. Previously much work has been done in characterizing these systems for spatial accuracy and precision. Much of this previous work examines single tracking systems or modalities. We have devised a method which allows for the characterization of a novel tracking system independent of modality and location. We describe the development of a phantom system which allows for rapid design and creation of surfaces with different geometries. We have also demonstrated a method of analysis of the data generated by this phantom system, and used it to compare Biosense-Webster's CartoXP, and Northern Digital's Aurora magnetic trackers. We have determined that the accuracy and precision of the CartoXP was best, followed closely by the Aurora's dome volume, then the Aurora's cube volume. The mean accuracy for all systems was better than 3mm and decays with distance from the field generator.
