Synopsis

Keywords: High-Field MRI, High-Field MRI, 11.7T, Signal-to-Noise RatioThe Iseult coil, developed for MRI of the human brain at 11.7T, was presented at last year’s ISMRM meeting. Here we show SNR phantom measurements in comparison with the Avanti2 coil, a replica of the Iseult coil tuned at 300 MHz (for 7T). We derive a new power dependence of the SNR vs B0.
