At present, nuclear magnetic resonance (NMR) imaging provides poor dynamic images, limited mainly to the rapid flow of fluids. This article presents a new means for employing an NMR machine to measure the perfusion of liquid through a plane. In medical applications, it provides a method of measuring the movement of liquid through an arbitrary plane slice in a body, e.g., the flow of liquids in an organ. In known techniques for perfusion measurement, data are collected during very short time intervals and related quadratically to the Fourier Transform of the velocity distribution function, which presents numerical difficulties in extracting information via a Fast Fourier Transform algorithm. The disclosed method yields data which is linearly related to the distribution function Fourier Transform.
