Umuyoboro muke wa Electromagnetic Field Active Shielding
Sisitemu ya MRI ni ibikoresho bisobanutse neza byerekana amashusho, bifite ibisabwa byinshi mubidukikije. Ikimenyetso cya NMR ni ikimenyetso gikomeye cyane, gishobora kwangirika hanze. Nkigisubizo, sisitemu ya MRI ikenera akenshi kuba ifite kasho ya Faraday (ibyumba bikingira) kugirango itandukanya interineti ya RF itinjira muri sisitemu. Ariko, akazu ka Faraday gafite uburyo bwiza bwo kwiyegereza umurongo wa radiyo, kandi ingaruka zo gukingira umuyoboro muke ni muto. Cyane cyane mugushiraho sisitemu ya MRI hafi ya metero, gariyamoshi, transformateur nini, lift, insinga zohereza amashanyarazi, nibindi. Ntabwo bigomba gushyirwaho akazu ka Faraday gusa, ahubwo na sisitemu yo gukingira igomba gushyirwaho kugirango sisitemu ya MRI yujuje ibisabwa byo gusuzuma. .
CSJ-ASH ni imikorere-yumurongo muke wa electromagnetic yumurima ukora sisitemu yo gukingira yatejwe imbere na Ningbo Chuanshan Jia Electromechanical Co., Ltd. insinga zohereza, ibikoresho bya transformateur, lift, nibindi CSJ-ASH igizwe nibice bitatu byingenzi: fluxgate high-precision probe, host, na coiling coil. Isesengura ryinshi rya fluxgate rishobora kumva ibidukikije byangiza amashanyarazi, kandi bigatanga ibimenyetso byamashanyarazi bihuye kugirango byemere kubakira. Nyuma yo gutunganyirizwa, uwakiriye asohora ibintu bihinduka bikurikira mugihe nyacyo, kandi ikibyara umusaruro uhinduranya imbaraga za magnetique mumashanyarazi yo gukingira kugirango uhagarike umurongo wa magneti, bityo ukamenya gukingira gukomeye kumashanyarazi make.
