摘要

Permanent magnet system intended for nuclear magnetic resonance imaging, in particular for examining the human body. It comprises two horizontal opposed and parallel pole pieces 1, 2 in the shape of a rectangular parallelepiped, made of a ferromagnetic material with a very high permeability, which are positioned one above the other and magnetically polarised by two parallelepipedal blocks of magnetised materials 3, 4 defining between them and with the pole pieces a central air gap 5, which also has a parallelepipedal shape, in which the human body to be examined is positioned.
