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 image. In this study, a novel triple-nuclear RF coil system capable of 1H / 19F / 23Na imaging was designed. The coil consists of a triple-tuned four-ring birdcage transmit coil and the tight fit local X-nuclei single-loop receive coils. A range of bench tests were performed by using the developed triple-nuclear coil. The performance evaluations showed that the coil system was appropriately tuned, matched and decoupled at 1H/19F/23NA frequencies when working simultaneously.
