The common scheme of using trap circuits for dual-tuned operation results in increased coil losses as well as problems in obtaining optimal tuning and matching at both frequencies. Against these reserved problems, the duel tuned RF coil combined with strip-line coils array and a birdcage coil has proven their performance at 7T. However, a loop coil generates more uniformed B1- field and has better coil sensitivity than a strip-line coil at 3T. In the study, we construct the dual coil combined with a H1 loop coils array and a Na23 birdcage coil as well as evaluate decoupling methods to solve inter loop coupling.
