Nidaamka MRI waa qalab ogaanshaha sawir-qaadista oo sax ah, kaas oo leh shuruudo sare oo ku saabsan deegaanka rakibidda. Calaamadda NMR waa signal aad u daciif ah, oo u nugul faragelinta dibadda. Natiijo ahaan, nidaamyada MRI badanaa waxay u baahan yihiin in lagu qalabeeyo baqashooyinka Faraday (qolalka gaashaanka) si looga sooco faragelinta RF ee dibedda ah inay gasho nidaamka. Si kastaba ha ahaatee, qafiska Faraday wuxuu leeyahay hoos -u -dhigid wanaagsan oo loogu talagalay raadiyaha soo noqnoqda raadiyaha, iyo saamaynta gaashaanka ee soo noqnoqoshada hooseysa waa mid xadidan. Gaar ahaan rakibidda nidaamyada MRI ee u dhow tareenada dhulka hoostiisa mara, tareenada, kuwa rogayaasha waaweyn, wiishashka, fiilooyinka gudbinta awoodda, iwm. Ma aha oo kaliya in qafiska Faraday la habeeyo, laakiin sidoo kale nidaamka gaashaamidda firfircoon waa in loo qaabeeyo si nidaamka MRI uu u buuxiyo shuruudaha ogaanshaha. .

CSJ-ASH waa nidaam gaashaammeed firfircoon oo heer-koronto-ku-soo-noqnoqosho sare leh oo heer sare ah oo ay soo saartay Ningbo Chuanshan Jia Electromechanical Co., Ltd. Waxay si wax ku ool ah u ilaalin kartaa aagagga elektromagnetiga DC, 50Hz/60Hz aagagga korantada soo noqnoqda ee korantada korantada fiilooyinka gudbinta, qalabka transformer, wiishashka, iwm Baaritaanka fluxgate ee saxda ah wuxuu dareemi karaa faragelinta beerta elektromagnetic-ka deegaanka, wuxuuna dhalin karaa calaamad koronto oo u dhiganta si uu ugu gudbiyo martida. Ka dib socodsiinta, martigeliyuhu wuxuu soo saaraa gadaal dambe oo soo raaca waqtiga dhabta ah, kan hadda jira wuxuu abuuraa aag birlabeed oo gadaal ka ah gariiradda gaashaanka si loo baajiyo faragelinta magnetic field, sidaasna ku garwaaqsado gaashaan-qaadka firfircoon ee aagagga elektromagnetic-ka ee soo noqnoqda.
