Title (EN) RADIO FREQUENCY COIL FOR MAGNETIC RESONANCE IMAGING
(FR) BOBINE RADIOFRÉQUENCE DESTINÉE À UNE IMAGERIE PAR RÉSONANCE MAGNÉTIQUE
(KO) 자기공명영상용 라디오 주파수 코일
Abstract: front page image
(EN) The present invention provides a radio frequency coil for magnetic resonance imaging. According to the present invention, the radio frequency coil for magnetic resonance imaging has an adjustable length and comprises: a dipole antenna having a specific resonant frequency according to the length; and electrical switches respectively positioned at both side surfaces of the dipole antenna. According to the present invention, the length of a single radio frequency coil can be randomly adjusted by using the electrical switches and a direct current in an ultra-high magnetic field, and the signals of multiple nuclides, not a single nuclide, can be acquired by using the single radio frequency coil, and thus the single radio frequency coil has multiple resonant frequencies.
(FR) La présente invention concerne une bobine radiofréquence destinée à une imagerie par résonance magnétique. Selon la présente invention, la bobine radiofréquence destinée à une imagerie par résonance magnétique comporte une longueur réglable et comprend : une antenne dipôle comportant une fréquence de résonance spécifique selon la longueur ; et des commutateurs électriques positionnés respectivement au niveau des deux surfaces latérales de l'antenne dipôle. Selon la présente invention, la longueur d'une bobine radiofréquence unique peut être réglée de manière aléatoire au moyen des commutateurs électriques et d'un courant continu dans un champ magnétique ultra-élevé, et les signaux de multiples nucléides, non d'un nucléide unique, peuvent être acquis au moyen de la bobine radiofréquence unique, et, par conséquent, la bobine radiofréquence unique comporte de multiples fréquences de résonance.
(KO) 본 발명은 자기공명영상용 라디오 주파수 코일을 제시하고 있다. 본 발명에 따른 자기공명영상용 라디오 주파수 코일은 길이에 따라 특정한 공진 주파수를 갖는 다이폴 안테나와, 상기 다이폴 안테나 양 측면에 각각 위치하는 전기적 스위치를 포함하며 길이 조정이 가능하다. 본 발명에 따르면, 단일의 라디오 주파수 코일을 초고자장에서 전기적 스위치와 직류를 이용하여 길이를 임의로 조절 가능하고, 단일의 라디오 주파수 코일을 이용하여 단일 핵종이 아닌 다수 핵종의 신호를 획득할 수 있으며, 이를 통해 단일의 라디오 주파수 코일에서 다수개의 공진 주파수를 가질 수 있는 효과가 있다.
