발명의 명칭: (EN) MRI-COMPATIBLE CARDIAC DEFIBRILLATOR
(FR) DÉFIBRILLATEUR CARDIAQUE COMPATIBLE IRM
요약서:
(EN) A magnetic-resonance-imaging-compatible (MRI-compatible) cardiac defibrillator includes: a defibrillator generator; first and second electric wires, each being electrically connected to said defibrillator generator; first and second defibrillation pads, each being electrically connected to a respective one of said first and second electric wires; and a low pass filter electrically connected between said defibrillator generator and said first and second electric wires to prevent a noise in an MRI image caused by a radiofrequency interference from the defibrillator as well as protect a patient and the defibrillator from MRI radiofrequency imaging signals, wherein said low pass filter has a cutoff frequency set such that differential mode noise at an MRI Larmor frequency is in an attenuated band while a system-test signal by said defibrillator generator is in a pass band of said low pass filter.
(FR) L'invention concerne un défibrillateur cardiaque compatible avec une imagerie par résonance magnétique (compatible IRM) comprenant : un générateur de défibrillateur ; des premier et second fils électriques, chacun étant connecté électriquement audit générateur de défibrillateur ; des premier et second plots de défibrillation, chacun étant connecté électriquement à l'un desdits premier et second fils électriques respectifs ; et un filtre passe-bas connecté électriquement entre ledit générateur de défibrillateur et lesdits premier et second fils électriques en vue d'empêcher un bruit dans une image IRM provoqué par une interférence radiofréquence provenant du défibrillateur, ainsi que de protéger un patient et le défibrillateur contre des signaux d'imagerie radiofréquence IRM, ledit filtre passe-bas comportant un ensemble de fréquences de coupure de sorte que le bruit de mode différentiel à une fréquence de Larmor d'IRM soit dans une bande atténuée, pendant qu'un signal de test de système par ledit générateur de défibrillateur est dans une bande passante dudit filtre passe-bas.
