Joint motion in an open MR unit using MR tracking

J Magn Reson Imaging. 1999 Jul;10(1):8-14. doi: 10.1002/(sici)1522-2586(199907)10:1<8::aid-jmri2>;2-2.


A system for active scan plane guidance during kinematic magnetic resonance (MR) examination of joint motion was developed utilizing an external tracking coil and MR tracking software. In a phantom study and during upright, weight-bearing, physiologic knee flexion, the external tracking coil maintained the scan plane through desired structures. Thus, MR tracking provides a robust method to guide the scan plane during MR imaging of active joint motion.
