The goal of this work is to implement a dual tuned sodium-proton coil as transceiver for sodium and transmitter for hydrogen with a high-density proton receive array and compare the proton imaging performance with a state-of-the-art single tuned knee coil. A double-tuned knee coil was constructed as a shielded birdcage and 15 channel proton receiver coil embedded within the double-resonant birdcage. The double-tuned coil was implemented with comparable proton quality and acceleration possibilities compared to the single-tuned alternative while also being able to acquire high SNR sodium images.
