Abstract
Nuclear magnetic resonance apparatus for forming an image representative of a velocity profile of a fluid flowing in a vessel in which the fluid is stimulated to produce a time-dependent magnetic resonance signal, Fourier-transformed data is derived from the time-dependent magnetic resonance signal, the stimulating is done so as to introduce, into a predetermined component of the Fourier-transformed data, spatially-dependent phase information indicative of the velocity profile of the fluid, and the predetermined component is extracted for display as the image representative of the velocity profile.
