Three 8-channel array designs are compared at 3T: a) a gapped array; b) a standard overlapped array with zero mutual inductance between nearest neighbors; and c) a gapped array with mutual-inductance-ing transformers between nearest neighbors. Preamp decoupling was used for all three. The gapped array provided the best SNR performance (respectively 18% and 24% better) since it had the lowest noise covariance.
