A novel double-tuned radio-frequency (RF) receiver coil for use in magnetic resonance imaging (MRI) systems has been demonstrated based on a birdcage-type circuit. The receiver coil utilises the end-ring current as well as the leg current of the birdcage-type circuit to detect the nuclear magnetic resonance (NMR) signals of different elements simultaneously. It was designed to detect the NMR signals of both 1H and 31P elements in a 4.7 T MRI system. The coil showed an excellent frequency response and provided clear magnetic resonance images of a Na2HPO4 phantom when used with the 4.7 T MRI system.
