A novel parallel transmit array design method is proposed that integrates both Maxwell and Bloch equations. The method is demonstrated to be better than traditional coils in dynamic multiband shimming and reduced field-of-view imaging scenarios to achieve better excitation accuracy and lower RF energy deposition, as well as robustness across multiple subjects and excitation schemes.
