Nuclear magnetic resonance apparatus.

摘要

An NMR apparatus capable of being used for both chemical analysis and imaging of a body without adjustment of the magnetic field strength of the magnet system used to define the equilibrium axis of magnetic alignment of the nuclei within the body. The apparatus incorporates two magnet systems (2, 35) each capable of independently defining an equilibrium axis of magnetic alignment to nuclei with a body to be examined by NMR techniques.
