As more advanced Parallel Transmit (PTx) technology at high field continues to emerge, the development of compatible Transmit-Receive(TxRx) arrays with good transmit and receive sensitivity as well as decoupling has become a greater priority. We describe here a shielded version of the 8 channel PTx suitable triangular array for head imaging at 7T MRI designed to increase B1+ coverage along z direction as well as keeping diverse B1 profiles for the individual elements. In-vivo experiments demonstrated the benefits and potential of using this Triangular array with PTx system.
