Receive arrays play a major role in capturing the signal-to-noise ratio (SNR) and parallel imaging performance improvements at ultrahigh-field MRI. A novel self-decoupled 64-channel receive array was built for human brain imaging and compared to a 32-channel receive array at 10.5T/447MHz. Experiments demonstrated a maximum noise correlation of 0.31 in the 64-channel receiver. Experimental SNR comparisons showed 1.95 times more SNR averaged over the sample relative to the 32-channel array at 10.5T. The 10.5T 32 channel receiver was previously shown to have 1.81 times more average SNR gain over the industry standard 32 channel array at 7T.
