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.
