ABSTRACT:
The invention is a method and apparatus for performing high speed, high resolution nuclear magnetic resonance imaging wherein the magnetic coils for inducing the desired magnetic fields and receiving the magnetic field caused by NMR are positioned to one side of the volume under observation. Disclosed coil configurations provide a relatively large volume homogenous Ho field and three orthogonal gradient fields, so as to create a relatively large volume of observation which is broken up into high resolution voxels by appropriate selection of each of the gradient fields. The voxel is shifted in space at time intervals by scaling one or more of the gradient fields at such time intervals.
