7 Tesla Whole-Slice and Localized Excitation Everywhere in the Human head

In this work, a multi-port excitation technique is numerically implemented at 7 Tesla MRI to provide 1) homogenous whole-slice (axial, sagittal, or coronal) head excitation and 2) highly localized excitation within the same slices, all with the same the RF coil. The method is tested using a full wave model of a coil loaded with an anatomically detailed human head mesh. The proposed approach is solely based on RF shimming. The results demonstrate that both whole-slice homogeneity as well as localized excitation can be achieved within any slice of the human head at 7 Tesla (298 MHz).
