The use of high channel count transmit arrays in the clinical setting has yet to become widespread, and the integration of prototype hardware with a clinical scanner for testing adds complexity. A simple 8-channel transmit array capable of operating in series or parallel resonance was implemented to facilitate testing of multiple parallel transmit platforms, in particular comparing voltage and current source excitations schemes. The transmit array has been successfully implemented on a 3T GE clinical scanner and can simply be inserted into the body coil (used as the receive coil) without the need for a decoupling network.
