Abstract
High electric permittivity materials (HPM) have been used to improve transmit efficiency and receive sensitivity in targeted regions. In this work we demonstrate improvements in the entire b rain by designing and implementing an integrated HPM shell for a head coil with 8-channel transmit and 30-channel receive arryas. The coil with HPM insert provides gains of approximately55% in transmit efficiency and 20% in SNR compared to an identical coil withou t the insert. [ABSTRACT FROM AUTHOR]
