Induced current elimination (ICE) method could efficiently reduce the element coupling in monopole and dipole arrays, and ultimately improve their SNR and parallel imaging performance. Nevertheless, in current ICE method, the decoupling element has possible effect on the original B1 field, leading to dark spots at the areas near decoupling elements. To address such effects, we introduce a new structure, electric-LC (ELC) resonator, for decoupling monopole arrays. Based on the simulation and experimental results, ELC resonators could also effectively reduce the coupling of monopoles and meanwhile have less influence on the original B1 fields of the elements.
