Most transmit array coils for imaging of the human head are based on cylindrical designs. This arrangement leaves most elements at a distance from the superior surface of the brain. We present here a combination of dipoles (on a cylindrical surface) and geometrically decoupled loops (on a plane tranverse to the axis of the cylinder) to bring some elements closer to the superior surface of the head.
