At high-fields, transmission line arrays and multi-channel TEM coils have show to be useful transceivers, but the extension to using these transmission line resonator arrays in a receive-only array has not been strongly pursued. Here we have developed a 16-element, receive-only transmission line resonator array to be used in conjunction with a 16-element transmission line vloume array for high-field imaging. The receiver array had improved SNR and spatial sensitivity then the larger volume array. The receiver array also shows improved cortical homogeneity over more traditional loop arrays
