g-factors at different reduction rate calculated based on the 7T head imaging acquired using the 8-channel primary resonator array and the 16-channel mixed array. With the convenient channel upgrade using the proposed mixed harmonic method, the parallel imaging performance of the 8-channel coil array is significantly improved.
