Synopsis

The lower natural abundance and gyromagnetic ratios of non-hydrogen nuclei require the use of a highly efficient RF coil to optimize the quality of the MR image and spectroscopy. In this study, a new quadruple-tuned RF coil system capable of 1H / 19F / 23Na /31P imaging was proposed, including the inner high-pass birdcage coil (31P) and a triple-tuned outer four-ring birdcage coil (1H / 19F / 23Na). The feasibility and performance of this proposed RF coil were evaluated and validated by the numerical electromagnetic simulation in the scattering parameters and B1+field distributions.
