Abstract

La présente invention concerne un outil de RMN à balayage latéral comportant un aimant principal (217), un second aimant (218), et une antenne d'émission-réception (219). Les aimants (217, 218) sont aimantés perpendiculairement à leur axe longitudinal. L'agencement des aimants donne une région active en arc (211).
