A magnetic resonant image of an object is produced by subjecting the object to an initial slice selection to provide an active region and by subjecting the active region to a plurality of 180.degree. RF pulses and appropriate amplitude modulated x and y gradients.

Echo planar imaging using 180 degrees pulses

The fluid transport properties of a porous media are determined by NMR imaging showing the fluid transport properties such as fluid velocity, fluid acceleration, fluid jerk, translational self diffusion, sample permeability to fluid transport, etc.

Method and apparatus for measuring fluid transport properties through

A nuclear magnetic resonance (NMR) method of producing a series of three or four dimensional spin parameter maps of a defined region, which spin parameter maps are displayable as a set of contiguous planar spin parameter maps with arbitrary orientation.
