The performances of a 32-channel receive coil array combined with a tight-fitted whole-brain dipole coil array were investigated. Functional MRI data targeting the auditory cortices was acquired. Noise correlation matrices, SNR and g-factor maps were measured. Compared to a commercial 32Rx, the in-house built 8T/32Rx coil array demonstrated higher robustness in the fMRI results. Lower noise correlation coefficients were measured with the in-house built 8Tx/32Rx coil array while the overall experimentally measured SNR and g-factor maps were comparable.
