Abstract
In a nuclear magnetic resonance experiment, the flows are measured by causing the orientation of the magnetic moments of the particles located in a slice to flip and by subsequently causing the scattering of the phases of the magnetic resonance signals to be reflected only for particles which have migrated into a slice adjacent to the slice in which the flipping has been done. It is shown that the relative dynamic range of the measured NMR signal for the moving parts in relation to the measured signal for the fixed parts becomes infinite.
