23Na MRI keeps increasingly demonstrating diagnostic value in a multitude of studies and clinical applications due to its capability to provide information on tissue viability. In order to co-register 23Na and 1H MR images, a double resonant 23Na/1H RF system is the optimal solution. In this work we present a clinical double-resonant RF system consisting of a shielded 23Na BC coil, a 16 channel 23Na Rx array and a local 1H Helmholtz coil inside the shielded 23Na BC coil. The complete system is demonstrated in EM simulations and initial feasibility measurements are performed.
