Title (EN) METHOD AND CIRCUIT ARRANGEMENT FOR OPERATING MULTI-CHANNEL TRANSMIT/RECEIVE ANTENNA DEVICES
(FR) PROCEDE ET ENSEMBLE CIRCUIT PERMETTANT DE FAIRE FONCTIONNER DES DISPOSITIFS D'ANTENNES DE TRANSMISSION/RECEPTION MULTICANAUX
Abstract: front page image
(EN)Methods and circuit arrangements for operating multi-channel transmit / receive antenna devices or arrangements especially for use in magnetic resonance imaging (MRI) systems are disclosed, by which a fully independent control of complete multi-channel RF transmit and receive chains can be conducted in a flexible way and new options like RF shimming, transmit sensitivity encoding (TransmitSENSE), RF encoding, determination of S- or Z-matrix prior to spin echo measurements, calibration, SAR (specific absorption rate) reduction etc. can be utilized or improved.
(FR)Cette invention concerne des procédés et des ensembles circuits permettant de faire fonctionner des dispositifs ou des ensembles d'antennes de transmission/réception multicanaux destinés spécifiquement à être utilisés dans des systèmes d'imagerie par résonance magnétique (IRM), laquelle invention permet d'une part d'effectuer une commande entièrement indépendante de chaînes de transmission et de réception RF multicanaux de manière souple et d'autre part d'utiliser ou d'améliorer de nouvelles options telles que le réglage RF, le codage de sensibilité de transmission (TransmitSENSE), le codage RF, la détermination de matrice S ou Z avant mesures d'écho de spin, l'étalonnage, la réduction du taux d'absorption spécifique (SAR), etc.
