I am involved in the optimization of the transmit only/receive only (ToRo) phased array for brain imaging at 9.4T. At the first step of this work, we optimized the transmit coil design containing 16 loops. As a key factor of this optimization, we used specific absorption rate (SAR) efficiency that was computed using methods of full-wave electrodynamic simulations. Currently, we optimize the geometry of the receive coil containing 32 elements. In near future, results of these simulations will be used to construct the prototype, test and evaluate it on the bench and in the MRI scanner.
