Novel and essentially lossless RF array coil elements decoupling method is introduced and analyzed. The proposed method is based on utilizing artificially engineered magnetic walls to effectively isolate the array elements. The efficacy of the decoupling method is demonstrated with 7T linear Tx/Rx visual cortex array for high-resolution fMRI. The method can be used quite systematically to decouple transmit-, receive- as well as transceive-arrays.
