The demand about invivo multi-nuclear MRI/MRS has increased
according to introduction of higher tesla MR system. The development of the dual
frequencies RF coil array keeps pace with this interest. At the overlay of both the proton and second-nucleus frequencies coil loops, inductive
coupling between coils has resolved to retain proton sensitivity and coil
tuning stability by LLC and LC tank circuit. However, they cause another mutual
coupling issue between the circuits and coil loops. Therefore, we introduce a simpler
and more efficient decoupling method than LLC and LC tank circuit in this study.
