Kinematic MR studies provide functional insights that corresponding static methods may not be able to provide. However, MR signal reception from body parts with large flexion ranges, such as the knee, can be challenging. Wearable RF coils that adapt well to a specific anatomy would offer good sensitivity and patient comfort at the same time. In the present work, we explore the practical utility of a wearable liquid metal coil. For this purpose a MR compatible knee bending setup is used. Static and kinematic imaging of a volunteer’s knee confirm sensitivity and coverage over the whole range of flexion.
