Abstract

Abstract Translated from French L'invention comporte au moins trois paires de bobines (1, 2, 3), coaxiales, d'axe (Oz) permettant deux accès à un volume d'examen, longitudinalement selon l'axe (Oz) et transversalement selon un plan de symétrie (4). Les neuf paramètres principaux caractéristiques des bobines sont choisis de façon à optimiser l'homogénéité du champ magnétique dans le volume d'examen. The invention comprises at least three pairs of coaxial coils (1, 2, 3), of axis (Oz) allowing two accesses to an examination volume, longitudinally along the axis (Oz) and transversely along a plane of symmetry (4). The nine main characteristic parameters of the coils are chosen so as to optimize the homogeneity of the magnetic field in the examination volume. Application à l'imagerie médicale par Résonnance magnétique nucléaire et au contrôle non destructif de structures industrielles d'encombrement et de formes diverses. Application to medical imaging using nuclear magnetic resonance and to non-destructive testing of industrial structures of size and various shapes.
