Highly decorrelated, high channel count receive arrays are a prerequisite to capturing the signal-to-noise ratio and acceleration performance potential of ultra-high field MRI. A self-decoupled 32-channel receive array was built for human brain imaging at 10.5T. Noise correlation and signal-to-noise ratio (SNR) of the RF coil were measured in phantom experiments at 10.5T. SNR was compared to a commercial 32-channel receiver array at 7T. Noise correlation matrices demonstrated effective decoupling of receive elements. Experimental SNR measurements demonstrated on average 60% higher overall SNR at 10.5T compared to 7T.
