Title: (DE) MAGNETRESONANZBILDGEBUNGSVORRICHTUNG UND VERFAHREN ZUM SCANNEN VON MAGNETRESONANZBILDERN DAMIT
(EN) MAGNETIC RESONANCE IMAGING APPARATUS AND METHOD OF SCANNING MAGNETIC RESONANCE IMAGE USING THE SAME
(FR) APPAREIL D'IMAGERIE PAR RÉSONANCE MAGNÉTIQUE ET PROCÉDÉ D'ANALYSE D'IMAGE DE RÉSONANCE MAGNÉTIQUE L'EMPLOYANT
Abstract:
(EN) A magnetic resonance imaging (MRI) apparatus includes a radio frequency (RF) controller configured to, for a repetition time period, control the MRI apparatus to apply, to an object, an RF preparation pulse having a coverage area covering two or more slices among a plurality of slices of the object, control the MRI apparatus to apply, to the object, RF pulses respectively corresponding to the plurality of slices, and move the coverage area. The MRI apparatus further includes a data acquirer configured to acquire magnetic resonance signals from the plurality of slices during the repetition time period.
(FR) L'invention concerne un appareil d'imagerie par résonance magnétique (IRM) qui comprend un dispositif de commande radiofréquence (RF) conçu pour, pendant une période de temps de répétition, commander l'appareil d'IRM pour qu'il applique à un objet une impulsion de préparation RF ayant une zone de couverture couvrant deux tranches ou plus parmi une pluralité de tranches de l'objet, commander l'appareil d'IRM pour qu'il applique à l'objet des impulsions RF correspondant respectivement à la pluralité de tranches, et déplacer la zone de couverture. L'appareil d'IRM comprend en outre une unité d'acquisition de données conçue pour acquérir des signaux de résonance magnétique provenant de la pluralité de tranches pendant la période de répétition.
