Title (EN) LOCAL COIL APPARATUS
(FR) APPAREIL À BOBINE LOCALE
(KO) 국부 코일 장치
Abstract: front page image
(EN)A local coil apparatus comprises: at least one radio frequency (RF) receiving coil; and a signal transceiver unit configured to be connected to a scanner for transmitting or receiving a RF signal and a control unit for controlling the local coil apparatus, wherein the RF receiving coil comprises: a decoupling circuit for cutting off induced current flowing through the RF receiving coil when the scanner performs a RF transmission operation; and a thermistor, the resistance of which varies according to the induced current, and the decoupling circuit cuts off the induced current flowing through the RF receiving coil, on the basis of a control signal received from the control unit through the signal transceiver unit.
(FR)L'invention concerne un appareil à bobine locale comprenant : au moins une bobine de réception à radiofréquence (RF); et une unité d'émetteur-récepteur de signal conçue pour être connectée à un dispositif de balayage pour émettre ou recevoir un signal RF et une unité de commande pour commander l'appareil à bobine locale, la bobine de réception RF comprenant : un circuit de découplage pour couper le courant induit circulant à travers la bobine de réception RF lorsque le dispositif de balayage effectue une opération d'émission RF; et une thermistance dont la résistance varie en fonction du courant induit et le circuit de découplage coupe le courant induit circulant à travers la bobine de réception RF, sur la base d'un signal de commande reçu de l'unité de commande par l'intermédiaire de l'unité d'émetteur-récepteur de signal.
(KO)국부 코일 장치는 하나 이상의 RF(Radio Frequency) 수신 코일, RF신호를 송수신하는 스캐너 및 국부 코일 장치를 제어하는 제어부와 연결되도록 구현된 신호 송수신부를 포함하되, RF 수신 코일은, 스캐너의 RF 송신 동작이 수행되는 경우, RF 수신 코일에 흐르는 유도 전류를 차단하는 디커플링 회로, 및 유도 전류에 따라 저항값이 변하는 서미스터를 포함하고, 디커플링 회로는 신호 송수신부를 통해 제어부로부터 수신한 제어 신호에 기초하여 RF 수신 코일에 흐르는 유도 전류를 차단한다.
