Self-decoupled radiofrequency coils reduce the electromagnetic coupling between the coil elements and eliminate the use of complex decoupling technologies. The use of a small value capacitor (Cmode) in a self-decoupled coil helps in eliminating the coupling between coil elements but causes a large electric field across the Cmode capacitor1.which may potentially cause a safety problem during imaging. In this study, we propose the use of a high dielectric sheet to reduce the electric field across the capacitor and thereby reducing the higher SAR in the subject.
