Preliminary results from a dual tuned 23Na sodium 1H proton knee coil are presented. A multiple ring birdcage design has been employed providing high sensitivity and uniformity to both nuclei without the need for frequency traps. Both coil sections are circularly polarized quadrature coils with direct drive cable connections. Cables are routed to a common potential node avoiding the need for baluns and avoiding parasitic cable loops. Registered images are presented for both sodium and proton acquisitions, avoiding the need to change the RF coil during the study
