    A hybrid method for 6-DOF tracking of MRI-compatible robotic interventional devices
    (2006-05) Krieger, A.; Metzger, G.; Fichtinger, G.; Atalar, Ergin; Whitcomb L. L.
    This paper reports a novel hybrid method of tracking the position and orientation of robotic medical instruments within the imaging volume of a magnetic resonance imaging (MRI) system. The method utilizes two complementary measurement techniques: passive MRI fiducial markers and MRI-compatible joint encoding. This paper reports an experimental evaluation of the tracking accuracy of this system. The accuracy of this system compares favorably to that of a previously reported active tracking system. Moreover, the hybrid system is quickly and easily deployed on different MRI scanner systems. © 2006 IEEE.
