A 128-channel receive array for cortical brain imaging at 7T was simulated and constructed. The tight-fitting brain-only coil was designed for use with a recently constructed head gradient system (Gmax = 200 mT/m and Smax = 900mT/m/s) for use with either a single channel birdcage Tx or a 24-channel pTx coil. The goal was to maximize cortical SNR and achieve the high acceleration needed for single-shot EPI based fMRI at high sub-millimeter isotropic resolution.
