A prototype 3-element open phased array knee coil for dynamic musculoskeletal (MSK) MR imaging of the knee was constructed and tested in a 1.5T Siemens Espree system. The acquired MR images of the knee joint, flexed to a variety of angles and also at the normal relaxed position, show that the open design concept is feasible and can facilitate diagnostic and functional assessment of knee injuries and pathology.
