Abstract
The invention relates to an MR method in which a navigator pulse is generated to excite a nuclear magnetization in a spatially limited volume by at least one RF pulse and at least two gradient magnetic fields having gradients which extend differently in respect of time and space. After the navigator pulse excitation, at least one MR signal is received from the volume in conjunction with a further gradient magnetic field for evaluation. In order to enhance the navigator pulse, a variation in time is imposed on the gradient magnetic fields in order to generate at least two MR signals which correspond to an excitation in the k space along mutually offset trajectories. The MR signals are combined.
