We propose a practical approach to designing transmit array (TxArray) precisely by integrating the equivalent circuit model of the manufactured structure and its EM simulation results to reduce the measurements and simulations differences caused by the imperfection in manufacturing. We investigate the performance of a shielded 8-channel degenerate birdcage head TxArray at 123.2MHz together with simulation and experiment to validate the proposed method. All self/mutual-inductances and self/mutual-resistances of the manufactured TxArray have been computed to determine the optimum capacitor values by minimization of the total return power from the coil.
