Synopsis

Keywords: Non-Array RF Coils, Antennas & Waveguides, Non-Array RF Coils, Antennas & WaveguidesMulti-frequency coils are typically known to have substantial losses as compared to their single-tuned counterparts. Here we investigate sensitivity tradeoffs of triple-tuned (1H-23Na-31P) trap designs on receive coils in a tightly controlled experiment to isolate the sensitivity effects of the traps. Triple-tuned LCC traps were shown to have significant improvement in sensitivity for 23Na and 1H as compared to an LC trap design. The increase came at the expense of 31P sensitivity, however continued optimization of the trap design will likely further improve the final experimental SNR.
