 Abstract: Multi-row arrays offer improved coverage in z-direction along with the capability to control the B1+ field in all spatial dimensions for high-field applications. This can be used to trade B1+ homogeneity against power efficiency in arbitrary volumes, depending on the desired application. However, numerical simulations must be provided to assess local SAR. In this work, we demonstrate the RF phase shimming capability of an inductively decoupled dual-row array for 9.4 T neuroimaging using time-domain simulations together with circuit co-simulation as well as RF shimmed, in vivo TSE and MP2RAGE images.
