Abstract
Les deux moitiés (10, 20) d'une bobine traditionnelle RF en sellette en spirale ou autre structure voisine utilisée en imagerie RMN ou en IRM à haute résolution, disposées de part et d'autre d'une bobine cylindrique, sont soumises à une rotation à partir de leur orientation conventionnelle, de 90· autour de l'axe B¿1? de manière à ce que les conducteurs (31, 32) soient parallèles à proximité du centre axial de la bobine RF.
