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 1 H and 31 P elements in a 4.7 T MRI system. The coil showed an excellent frequency response and provided clear magnetic resonance images of a Na 2 HPO 4 phantom when used with the 4.7 T MRI system.
