(KO) RF 송신 효율이 개선된 자기공명 영상용 RF 코일
Abstract:
(EN) The aim of the present invention is to provide a magnetic resonance imaging RF coil capable of improving RF transmission efficiency without reducing signal sensitivity by substituting a RF shield which is conventionally arranged external to the RF coil, and to that end, the present invention comprises: a looped transmission and reception coil (110) connected to a cable for RF transmission and reception, and provided with a first inductor (111); and a looped power transmission coil (120) provided with a second inductor (121) adjacent to the first inductor (111), and arranged on a different plane distanced from the transmission and reception coil (110).
(FR) Le but de la présente invention est de fournir une bobine RF d'imagerie par résonance magnétique capable d'améliorer l'efficacité de transmission RF sans réduire la sensibilité de signal par substitution d'un blindage RF qui est disposé de manière classique à l'extérieur de la bobine RF, et à cet effet, la présente invention comprend : une bobine d'émission et de réception en boucle (110) connectée à un câble pour une émission et une réception RF, et pourvue d'une première bobine d'induction (111) ; et une bobine de transmission de puissance en boucle (120) pourvue d'une seconde bobine d'induction (121) adjacente à la première bobine d'induction (111), et agencée sur un plan différent à distance de la bobine d'émission et de réception (110).
(KO) 본 발명은 종래에 RF 코일의 외측에 배치되는 RF쉴드를 대체하여 신호 민감도의 감소 없이 RF 송신 효율을 개선할 수 있는 자기공명 RF 코일을 제공하고자 하는 것으로, RF 송수신을 위한 케이블과 연결되며, 제1인덕터(111)가 구비되는 루프 형태의 송수신용 코일(110)과; 상기 제1인덕터(111)와 인접하여 제2인덕터(121)가 구비되며, 상기 송수신용 코일(110)과 서로 다른 평면 상에 이격되어 배치되는 루프 형태의 전력송신용 코일(120)을 포함한다.
