Double-Tuned 31P/1H Human Head Array with High Performance at Both Frequencies for Chemical Shift Spectroscopic Imaging (CSI) at 9.4T
{SNR enhancement at ultra-high field (UHF, \textgreater7T) is very critical for X-nuclei imaging. X-nuclei CSI of a human brain is potentially valuable for diagnostics of many diseases. CSI benefits from a whole-brain coverage and a high transmit performance not only at X- but also at 1H-frequency. It is rather difficult to optimize the DT-array at both frequencies at the same time. Therefore, often the performance of the X-nuclei portion of the RF array coil is optimized while the 1H-array performance is compromised. In this work, we developed a novel DT-array, which provides good performance at both 31P and 1H frequencies.}
