In the design of optimized radiofrequency excitation pulse with limited amplitude, the variance of the pulse excitation efficiency is taken into account to improve the excitation efficiency. It was shown that this method can significantly reduce the inhomogeneity of broadband excitation. The effects of different weights and pulse amplitude restrictions are also discussed in terms of how to achieve better excitation results.
