We have developed a two-sided RF resonator based on 8-channel array design for breast MR imaging at 7T. The RF resonator was evaluated by means of modeling and simulations as well as successful empirical testing involved with a breast phantom and two normal volunteers. Future studies include optimization of phases and amplitudes for B1 shimming and combination with Rx array insert.
