Head gradients constrain the dimensions of RF coils. Two 7T transmit TEM volume coils, one inductively coupled, one decoupled for parallel transmit, were designed to fit the head gradients. Each coil was equipped with an actively detuned, pre-amplifier decoupled, volume receiver array in close proximity to the transmitter. The performance of each is evaluated. Efficient independent transmit and receive volume arrays can be constructed in this tight configuration.
