Dipole antennas have been used for human imaging at ultra-high field (UHF, >7T). However, for head imaging, dipoles must be substantially shortened, which often cause poor (~ -10dB) decoupling. Common decoupling methods are difficult to use due to distant location of dipoles. Alternatively, adjacent transmit dipoles can be decoupled using passive dipole antennas placed parallel between them. Such passive dipoles may interact destructively with the RF field of the transmit array. In this work, we developed a novel decoupling method of adjacent transmit dipoles by using modified perpendicular passive dipole antennas. The constructed array demonstrated good decoupling and whole-brain coverage.
