title: Very slow flow imaging.
abstract: Two methods allowing imaging of very slow coherent flows are presented. The first method is based on the use of a radiofrequency field gradient. The second method is based on the use of gradients of the main field. Both methods include suppression of signal from stationary spins. A flow contour map is obtained which allows quantitative determination of velocity. The methods were proved to be efficient to image velocities as low as 10 microns.s-1.
