Registration in interventional procedures with optical navigator

J Magn Reson Imaging. 2001 Jan;13(1):93-8. doi: 10.1002/1522-2586(200101)13:1<93::aid-jmri1014>3.0.co;2-8.

Abstract

Performing interventional procedures in the close proximity to an MR scanner widens the range of operations available for an optical tracking system. In order to gain the full benefits from both unrestricted use of surgical instruments outside the magnet and intraoperative imaging, a method for transferring the registration data of the optical navigator between two locations is required. An optical tracking system, which provides such a transfer method and tracks patient position during a surgical procedure, has been developed, tested, and demonstrated with two patient cases. J.
