Joint motion in an open MR unit using MR tracking

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.J. Magn. Reson. Imaging 1999;10:8–14. © 1999 Wiley‐Liss, Inc.
