Joint motion in an open MR unit using MR tracking

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