Based on the principle of birdcage coil and the decoupling theory of array coil, a design scheme for dual-nuclear magnetic resonance imaging (MRI) coil is proposed. A LC parallel trap is used to improve the adaptability of the inductive decoupling scheme. According to the design scheme and simulation, a 1H/31P dual-nuclear parallel MRI coil is fabricated for a 4.7 T system. Dual-nuclear parallel imaging experiments are carried out on a custom-built MRI system to verify the feasibility of the coil design.
