Abstract

In this paper, the accuracy of intraoperative registration using cone-beam CT for computer-assisted surgery is preliminarily evaluated. Since cone-beam CT enables whole-surface detection of bone without surgical exposure, highly accurate registration is potentially attainable. In in vitro experiments, much higher accuracy could be attained by acquiring the intraoperative bone surface using cone-beam CT (0.56 mm) as compared with that of our routinely used protocol employing a 3-D positional sensor (1.43mm).
