RF coils with quadrature elements have higher sensitivity compared to those with simple loop elements, but the final composite images produced using these coils exhibit non-uniform intensity over the FOV. If two quadrature elements are used for simultaneous acquisition of independent FOVs, as for bilateral breast imaging, the coupling from the quadrature coils exhibits an artificial non-linear spatial variation. This work deals with the decoupling of signal for such bilateral breast imaging studies acquired with quadrature coils.
