A transmit/receive RF array was built for imaging the shoulder and upper extremities at 7 Tesla. Eight meander stripline elements were aligned on a c-shaped holder which can be split into two parts for easy patient positioning. The coil allows imaging of either the right or left upper extremity. in vivo images of the shoulder and elbow revealed uniform excitation over the whole field-of-view in both gradient and spin echo images, rendering fine anatomical details of cartilage, bone, nerves, vasculature, and tendons.
