Traveling-wave MRI utilizes the far field of a single piece patch antenna to generate homogeneous RF field covering large size imaging samples. In this work, we demonstrate a method to applying the traveling wave technology to parallel excitation and reception by using a multi-element patch antenna array. Each array element is a CP patch antenna which generates quadrature RF fields. FDTD simulation results demonstrate the excellent decoupling among elements, great g-factors at various reduction factors for 1D SENSE, demonstrating the feasibility of parallel imaging using traveling-wave.
