Title
(EN) SYSTEM AND APPARATUS FOR OVERLAPPING PHASED-ARRAY COILS FOR CURVED SURFACES
(FR) SYSTÈME ET APPAREIL DE CHEVAUCHEMENT DE BOBINES RÉSEAU À COMMANDE DE PHASE DESTINÉES À DES SURFACES INCURVÉES
Abstract
(EN) A magnetic resonance (MR) coil assembly includes a first row of coil elements, wherein the first row is a curved row and configured to conform to a first body curvature in a cone shape when the first row is bent and wrapped around the first body curvature; and a second row of coil elements, wherein the second row is a straight row and configured to conform to a second body curvature in a cylinder shape when the second row is bent and wrapped around the second body curvature, wherein each coil element in the first row has a first area and each coil element in the second row has a second area, and wherein the first area is larger than the second area. The first curved row can also be deployed without a second curved row.
(FR) Un ensemble bobine à résonance magnétique (MR) comprend une première rangée d'éléments de bobine, la première rangée constituant une rangée incurvée et conçue pour se conformer à une première courbure de corps en forme de cône lorsque la première rangée est pliée et enroulée autour de la première courbure de corps; et une seconde rangée d'éléments de bobine, la seconde rangée constituant une rangée droite et conçue pour se conformer à une seconde courbure de corps en forme de cylindre lorsque la seconde rangée est pliée et enroulée autour de la seconde courbure de corps, chaque élément de bobine dans la première rangée comprenant une première zone et chaque élément de bobine dans la seconde rangée comprenant une seconde zone, et la première zone étant plus grande que la seconde zone. La première rangée incurvée peut également être déployée sans seconde rangée incurvée.
