ABSTRACT:
For MR image acquisition, a sequence of individual measurements that are each composed of an excitation phase and a read-out phase is implemented. In the read-out phase, a nuclear magnetic resonance signal is read out that is allocated to only one point in the k-space defined by a preceding phase-coding gradient. A phase-coding gradient remains activated during a group of individual measurements and changes in size from individual measurement-to-individual measurement. Switching this phase-coding gradient in every individual measurement is thus avoided, so that ramp times can be eliminated and the overall data acquisition procedure is considerably shortened.
