A novel method for double tuning a single nuclear magnetic resonance (NMR) probe, providing two resonances to a single output, simultaneously is described. Both frequencies provide a high sensitivity and are easily tuned with special noninteracting frequency-decoupling circuits. The 1H (proton) imaging mode of the double-tuned surface coil is actively decoupled from the whole-body, circularly polarized transmit resonator by activating a pin diode circuit. Results for a phantom containing both water and phosphorus acid are shown
