Approaching Ultimate Intrinsic SAR in RF shimming using high-permittivity materials at 7 Tesla
PURPOSE: To evaluate the effect of integrated high-permittivity materials (HPMs) on excitation homogeneity and global SAR for transmit arrays at 7 Tesla. METHODS: A rapid electrodynamic simulation framework was employed to calculate L-curves associated with excitation of a uniform 2D profile in a di...
