Experimental protocol of accuracy evaluation of 6-D localizers for computer-integrated surgery: Application to four optical localizers

Abstract

This paper describes an experimental protocol in order to evaluate the accuracy of localizers for computer-integrated surgery (CIS), and the result of the evaluation for four commercially available optical localizers (Optotrak, FP5000, Polaris active and passive). This paper shows that the four systems have static xyz accuracy compatible with most of CIS applications, but they significantly differ when comparing their accuracy of moving rigid bodies.
