Abstract: front page image
(EN) The present invention relates to a multi-channel RF coil array for a magnetic resonance imaging device and, more particularly, to a multi-channel transmission-dedicated RF coil using multiple circular polarized (CP) modes in a super-high-frequency magnetic resonance imaging device. The present invention provides a multi-channel RF coil array for a magnetic resonance imaging device comprising as many as L coil elements that surround the subject circularly, wherein the L coil elements are classified into a plurality of coil groups comprising a plurality of coil elements, a plurality of current phase values, which increase by an integer multiple of 360°/L, are applied to the plurality of coil elements belonging to each coil group, and the plurality of current phase values, which are applied to each coil group, are applied independently of a plurality of current phase values applied to a different coil group. The present invention is advantageous in that a plurality of current phase values, which are applied to each of the first coil group and the second coil group, can be applied independently of each other, making it possible to form a uniform magnetic field.
(FR) La présente invention concerne un réseau de bobines RF multi-canal pour un dispositif d'imagerie par résonance magnétique et, plus particulièrement, une bobine RF dédiée à une transmission multi-canal utilisant de multiples modes à polarisation circulaire (CP) dans un dispositif d'imagerie par résonance magnétique à super-haute fréquence. La présente invention concerne un réseau de bobines RF multi-canal pour un dispositif d'imagerie par résonance magnétique comprenant jusqu'à L éléments bobines qui entourent le sujet de manière circulaire, les L éléments bobines étant classés en une pluralité de groupes de bobines comprenant une pluralité d'éléments bobines, une pluralité de valeurs de phase de courant, qui augmentent d'un multiple entier de 360°/L, sont appliquées à la pluralité d'éléments bobines appartenant à chaque groupe de bobines, et la pluralité de valeurs de phase de courant, qui sont appliquées à chaque groupe de bobines, sont appliquées indépendamment d'une pluralité de valeurs de phase de courant appliquées à un groupe de bobines différent. La présente invention est avantageuse en ce qu'une pluralité de valeurs de phase de courant, qui sont appliquées à chacun du premier groupe de bobines et du second groupe de bobines, peuvent être appliquées indépendamment l'une de l'autre, ce qui permet de former un champ magnétique uniforme.
(KO) 본 발명은 자기공명영상장치용 다채널 RF 코일 어레이에 관한 것으로, 보다 상세하게는 초고주파 자기공명 영상장치에서 다수 개의 CP(circular polarized) 모드를 이용한 다채널 송신전용 RF 코일에 관한 것으로서, 자기공명영상장치용 다채널 RF 코일 어레이에 있어서, 상기 다채널 RF 코일 어레이는 피검사체를 원형으로 둘러싸는 L 개의 코일 엘리먼트들을 포함하며, 상기 L 개의 코일 엘리먼트들은 복수 개의 코일 엘리먼트들로 구성되는 복수의 코일 그룹으로 구분되며, 각각의 코일 그룹에 속하는 복수 개의 코일 엘리먼트들에는 360°/L 의 정수 배씩 증가하는 복수의 전류위상 값들이 적용되되, 각각의 코일 그룹에 인가되는 상기 복수의 전류위상 값들은 다른 코일 그룹에 인가되는 복수의 전류위상 값들에 대해 독립적으로 적용되는 자기공명영상장치용 다채널 RF 코일 어레이를 제공하여, 제1코일 그룹과 제2코일 그룹 각각에 인가되는 복수의 전류위상 값들이 서로 독립적으로 적용될 수 있게 됨으로써, 균일한 자기장의 형성이 가능해지는 효과가 있다.
