In this work, an optimal control framework and its application for the development and improvement of $$$B_1^+-$$$ and $$$\Delta B_0-$$$robust, slice-selective inversion pulses is introduced. The optimized RF pulse shows superior performance compared to adiabatic, state of the art pulses through simulations, phantom experiments, and in vivo measurements. Measurements on a 3T MR system revealed improved slice-profile quality of the optimized pulse, especially for low $$$B_1^+$$$ and high $$$\Delta B_0$$$. Since the performance is independent of the field strength, its application in ultrahigh-field spectroscopy seems straightforward.
