Abstract
An apparatus for nuclear magnetic resonance scanning and imaging which employs a primary magnetic field, an rf field, and a detector for detecting a nuclear magnetic resonance signal, the primary magnetic field being produced by an assembly of relatively low energy flux magnetic material combined with an assembly of relatively high energy flux magnetic material. The magnetic flux of the relatively low energy flux magnetic material is concentrated in a magnetic flux conductor means which is in turn combined with the magnetic flux of the relatively high energy flux magnetic material and is concentrated at a pole piece.
