High electric permittivity materials (HPM) have been used to improve transmit efficiency (B1+) and receive sensitivity in targeted regions. In this work we demonstrate improvements in the entire brain by designing and implementing an integrated HPM shell for a head coil with 8-channel transmit and 30-channel receive arrays. The coil with HPM insert provides gains of approximately 55% in transmit efficiency and 20% in SNR compared to an identical coil without the insert.
