Concentrically Shielded Surface Coils - A New Method for Decoupling Phased Array Elements

In this abstract we present a new method of decoupling neighboring elements based on the use of concentric shields which is compatible with a gapped coil arrangement and yields good SNR and good isolation between the elements even at 1.5T. Nevertheless, the Q drop shows that the shielded coil can be made sample noise dominant and with sufficient SNR for use in an array arrangement. We believe this general concept will be useful for the construction of arrays with a large number of elements.
