要旨

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.
