NMR imaging technique provides high resolution

A new tool is being developed for producing two‐ and three‐dimensional images of the distribution of material within an arbitrary object. Christened “zeugmatography” by Paul Lauterbur, one of the leaders in the field, the nuclear‐magnetic‐resonance technique generally involves applying an inhomogeneous magnetic field to spread out the nmr signal in space. Ultimately, one can then deduce the spatial distribution of material, either by mathematical or analog manipulations.
