Dual tuned coils, often used for X-nuclei imaging,
compromise coil performance at both frequencies.
Moreover, to acquire proton reference image covering the
whole brain at 400 MHz, conventional dual tuned birdcage
cannot be used due to wavelength effects. A combination
of three coil arrays was developed to maximize the
receive sensitivity at the sodium frequency and to
provide proton signal covering the whole brain for
anatomical localization and B0 off-resonance correction.
