 Abstract: The requirements for implementing a multi-purpose, pTx-enabled RF setup for whole-brain imaging at 9.4 Tesla are high. They include transmit arrays with sensitivities distributed in all dimensions, receive hardware for high-SNR parallel signal reception, numerical simulations for compliance with SAR limits as well as rapid, volumetric calibration scans. In this work, we report our progress in achieving these objectives. A 16-channel dual-row Tx / 31-channel Rx-array combination was interfaced to an 8-channel pTx system. SAR was evaluated numerically, rapid calibration scans were acquired using a 3D DREAM sequence and superior excitation quality using Spokes pulses is demonstrated in vivo.
