In this study, a nested dual-tuned proton-sodium multi-channel loop-array transceiver coil was designed and constructed for 9.4T MRI, which could provide images for both proton and sodium at the same location. This coil adopts nested structure, which contains 8-channel transceiver loop elements respectively, and each loop is equipped with an independent transmit/receive circuit. The coil array was simulated for B1 field distribution and was further tested on a 9.4T whole-body MRI platform with home-built spectrometer. Proton and sodium images on a water phantom were successfully collected on this system with high quality.
