Claim:
1. A method to determine a control sequence for a magnetic resonance system comprising a plurality of different, independent radio-frequency (RF) transmission channels, said method comprising: in a computerized processor, defining a control sequence to generate an image series of a defined image region of an examination subject, said control sequence comprising a multichannel pulse train that causes said different independent RF transmission channels to radiate respective RF pulse trains in parallel; in said computerized processor, including an excitation pulse in said multichannel pulse train configured to excite said image region, and including a subsequent plurality of refocusing pulses that respectively excite nuclear spins so as to produce an echo signal to acquire raw data for each image of the image series; in said computerized processor, automatically determining at least one defined marking region within said image region that is dependent on a structure in the subject to be depicted in said image region, and configuring said multichannel pulse train to include a saturation pulse before said excitation pulse, said saturation pulse being configured to saturate nuclear spins at or in said at least one marking region upon emission of said saturation pulse; and emitting an electronic signal from said computerized processor, representing said control sequence, in a form for operating said magnetic resonance system according to said control sequence.
