Claim:
1. A method configured for detecting and correcting magnetic resonance (MR) image data, comprising: with a control computer, operating an MR data acquisition unit with a first acquisition sequence in order to acquire MR data from a first slice of a subject, and in order to generate a basic magnetic field having a basic field direction, said first acquisition sequence producing a magnetization of nuclear spins in said first slice where the produced magnetization occurs in a plane that is transverse to the basic field direction and in which the produced magnetization has a phase that exhibits a phase evolution represented as a first coherence curve; with a control computer, operating said MR data acquisition unit in order to acquire MR data from a second slice of the subject, said second acquisition sequence producing a magnetization of nuclear spins in said second slice where the produced magnetization in the second slice occurs in another plane that is transverse to the basic field direction and in which the produced magnetization has a phase that exhibits a phase evolution represented as a second coherence curve, wherein said first acquisition sequence and said second acquisition sequence are at least partially temporally overlapping so that said magnetization of said nuclear spins in said first slice and said magnetization of said nuclear spins in said second slice occur simultaneously at, at least one point in time, in which the overlapping occurs; with a control computer, operating said MR data acquisition unit with a slice-selective correction data acquisition step in order to acquire MR signals from only said first slice, thereby obtaining correction data; with a control computer, operating said MR data acquisition unit in order to implement at least one correction assistance step that suppresses a signal contribution of said second slice that occurs during said slice-selective correction data acquisition step, and that reestablishes said first and second coherence curves after said correction data acquisition step; and from said control computer, making said MR data acquired from said first slice in said first acquisition sequence and said MR data acquired from said second slice from said second acquisition sequence, and said correction data, available in electronic form in order to permit further correction processing when desired.
