Synopsis

Keywords: Non-Array RF Coils, Antennas & Waveguides, RF Arrays & SystemsCurrent state-of-the-art RF coils for X-nuclear MRS/MRI studies typically use two separate sets of RF coils operating at the X-nuclear and proton frequencies, respectively. Here, we introduce a new coil concept whereby large-size loop coil with split capacitors which can be simultaneously tuned and matched to 17O and 1H Larmor frequencies for 7T human imaging application. Importantly, this novel coil exhibits excellent performance in proton and X-nuclear imaging, therefore, it provides a simple RF coil solution, particularly for ultrahigh field (UHF) multinuclear brain MR imaging applications.
