This study investigated the feasibility of applying forward and reversed preamplifier decoupling techniques for low and high impedance coils, respectively, at 1 MHz. At a low field MRI, e.g. 1 MHz, the choice of components needed for interface circuitry together with availability of preamplifiers with low input impedance is challenging. In this study we demonstrated that using a high impedance coil with a lower number of turns achieved better decoupling levels than that of a low impedance coil. In addition, the minimum requirement for the input resistance of a preamplifier at 1 MHz was investigated.
