Preparing a magnetic resonance imaging method in compliance with stimulation-based limitations

A preparation device comprising:

• a representative-data generation unit configured to generate a plurality of representative pulse sequence segments, each of which is associated with a reference gradient amplitude of a gradient pulse having a highest stimulation potential of the representative pulse sequence segment, and a stimulation potential of which is representative of a group of partially different pulse sequences;
• a rise determination unit configured to determine, for each of the representative pulse sequence segments, a maximum gradient slew rate for which a permitted maximum value of the stimulation potential is not exceeded;
• a selection unit configured to determine and select, for a measurement protocol for a magnetic resonance imaging examination, one of the representative pulse sequence segments according to a gradient amplitude of the gradient pulse having the highest stimulation potential of a pulse sequence segment of a pulse sequence on which the measurement protocol is based;
• an adaptation unit configured to adjust the pulse sequence segment of the pulse sequence on which the measurement protocol is based in such a way that a maximum gradient slew rate associated with the selected representative pulse sequence segment is also not exceeded by the pulse sequence segment of the pulse sequence on which the measurement protocol is based;
• wherein raw MR data of the object is acquired using the pulse sequence corresponding to the measurement protocol.
