Abstract
Workers in medical robotics and computer-assisted surgery are increasingly concerned with the accuracy of rigid registration of preoperative medical images to intraoperative data. Much of the work on evaluation methods is limited by a fundamental dilemma: either the method works only in vitro and provides absolute accuracy, or the method works in vivo but provides only relative accuracy.
Previously, we developed a biocompatible fiducial marker and a CT-based detection technology that make it possible to evaluate the absolute in vivo accuracy of registrations. We have now developed a mathematical approach to evaluating accuracy, and have applied the method in a phantom study.
