Claim Text:
1. A method for determining a set of control parameters of a control sequence for a magnetic resonance device that allows optimally homogeneous excitation for an object to be recorded and imaging regions, the control sequence comprising single pulses that are to be emitted in parallel for a plurality of individually controllable high frequency transmission channels, wherein the set of control parameters is chosen from linear combinations of sets of basic parameters of a plurality of sets of basic parameters associated with different volumes of a plurality of volumes, the basic parameters comprising a high frequency amplitude and a high frequency phase for each transmission channel, the method comprising: measuring the plurality of volumes as the imaging regions; determining a mean flip angle for each set of basic parameters of the plurality of sets of basic parameters in the imaging region where the object exists, the determining using the set of basic parameters with a first measuring method; determining, for each set of basic parameters of the plurality of sets of basic parameters, a signal strength of a magnetic resonance signal generated in the case of a reference flip angle of a second measuring method at which a signal maximum or a signal minimum exists; and selecting, using the linear combinations of the sets of basic parameters associated with the different volumes, the set of basic parameters of the plurality of sets of basic parameters having a signal strength for the reference flip angle as the set of control parameters.
