A helmet shaped coil former made of high permittivity material is simulated with an 8 channel transmit/receive coil as an evaluation step towards coil construction. The addition of the high permittivity material improves performance in both transmit and receive but the choice of a permittivity that is too high may lead to undesired split-resonance effects.
