Combined triple tuned X-nuclei (2H, 23Na, 31P) birdcage and 1H 4 channel dipole array for head imaging at 7T

One method to achieve multiple coil resonances involves the use of diode or microelectromechanical system (MEMS) switches to toggle between resonances at proton and x-nuclei frequencies. While this approach provides a straightforward means to activate or deactivate coils corresponding to the desired nucleus, it does not allow simultaneous multinuclear data acquisition hat is required to eliminate temporal disparities. In this work we present a triple tuned birdcage for truly simultaneous imaging of X-nuclei combined with a proton dipole array at 7T. We show initial phantom imaging experiments and compare SNR with existing RF coils.
