Actuating a magnetic resonance device with saturation

A method for actuating a magnetic resonance system having a radiofrequency (RF) unit designed to generate an RF pulse for saturation of nuclear spins in an area under examination of an object under examination, the method comprising:

• loading a B0 map of the magnetic resonance system;
• loading frequency information on nuclear spins to be saturated in the area under examination;
• ascertaining at least one global RF saturation pulse for global saturation of the nuclear spins to be saturated on the basis of the B0 map and the frequency information;
• and
• emitting the global RF saturation pulse via the radiofrequency unit of the magnetic resonance system, wherein the emitted global RF saturation pulse is adjusted in terms of time and space to static and/or dynamic magnetic field changes due to system-specific causes.
