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.
