Universal Parallel Transmit Pulse Design for 3-Dimensional Local-Excitation: A 9.4T Simulation Study

{This study introduces a parallel-transmission (pTx) radio-frequency (RF) pulse-design-method to create an universal pTx RF-pulse that excites the same 3-dimensional local excitation pattern with a desired flip-angle in different human heads at 9.4T. Thus, it prospectively abandons the need for time-consuming subject specific B1+ mapping and pTx-pulse calculation during the scan session. The resulting universal pulses created magnetization profiles with an only marginal worse Normalized-Root-Mean-Square-Error (NRMSE) compared to the magnetization profiles produced by the pulses tailored to individual heads.}
