Abstract: A magnetic resonance imaging method and apparatus for obtaining images of slices of a body placed in a static magnetic field. During the sampling of one NMR signal, an additional second gradient magnetic field is impressed on the body to acquire data. These data are additionally sampled during each sampling. This enables the number of data to be increased and the number of repetitions to be reduced, thereby accomplishing a Fourier transformation at a higher speed.
