In a method for controlling a magnetic resonance system with multiple radio-frequency transmission channels, via which parallel RF pulse trains are emitted in operation, as well as a magnetic resonance system and a pulse optimization device therefor, RF pulse trains respectively include at least one radio-frequency pulse. The RF pulse trains are initially determined so that a minimum B1 field maximum value is not exceeded by the radio-frequency pulse. In an examination subject-specific adjustment step, a current component-dependent B1 field maximum value is then determined, and the radio-frequency pulse is temporally shortened, with its amplitude being increased dependent on the current component-dependent B1 field maximum value. |
