Title
(EN) PROPELLER ECHO PLANAR TIME-RESOLVED IMAGING WITH DYNAMIC ENCODING
(FR) IMAGERIE À RÉSOLUTION TEMPORELLE À ÉCHO-PLANAR DE PROPULSEUR À CODAGE DYNAMIQUE
Abstract
(EN)
Magnetic resonance imaging ("MRI") using a PROPELLER echo-planar time- resolved imaging with dynamic encoding ("PEPTIDE") scheme is described. The PEPTIDE scheme combines a PROPELLER-style trajectory with an echo-planar time-resolved imaging ("EPTI") acquisition framework, along with dynamic-updating of sensitivity- encoding information.
(FR)
L'invention se rapporte à l'imagerie par résonance magnétique (« IRM ») faisant appel à une imagerie à résolution temporelle à écho-planar de propulseur à schéma de codage dynamique (« PEPTIDE »). Le schéma PEPTIDE combine une trajectoire de style PROPULSEUR avec une structure d'acquisition d'imagerie à résolution temporelle à écho-planar (« EPTI »), conjointement avec une mise à jour dynamique d'informations de codage de sensibilité.
