Title (EN) TUNABLE NMR PROBE HEAD AND/OR COIL
(FR) TÊTE ET/OU BOBINE DE SONDE RMN ACCORDABLE
Abstract:
(EN) The NMR probe head comprises a birdcage resonator having two conductive rings (20a, 20b) and a plurality of bar-shaped connectors (22) between them. The connectors (22) are equipped with reactance elements (23a, 23b). At least some of the reactance elements (23a, 23b) can be tuned individually in order to compensate for asymmetries in the birdcage resonator.
(FR) Selon la présente invention, la tête de sonde RMN comprend un résonateur en cage d’oiseau comportant deux anneaux conducteurs (20a, 20b) et une pluralité de connecteurs en forme de barre (22) entre ceux-ci. Les connecteurs (22) sont équipés d’éléments de réactance (23a, 23b). Au moins certains des éléments de réactance (23a, 23b) peuvent être accordés individuellement afin de compenser des asymétries dans le résonateur en cage d’oiseau.
