The work presented in this abstract is the study of a new decoupling circuit for RF surface coils for MR imaging. The new decoupling circuit is designed to operate in two modes, one is for normal mode in which the appropriate DC biasing is present and the other one is abnormal mode in which the DC biasing is absent. The study was focused on the comparison between the characteristics of traditional active decoupling circuit and the proposed hybrid circuit. We provided experimental testing results including impedance data and temperature rise measurement due to RF heating.
