ʻO ka ʻōnaehana MRI kahi pono diagnostics kiʻi pono kiʻekiʻe, nona nā koi kiʻekiʻe no ka hoʻonohonoho hoʻonohonoho. ʻO ka hōʻailona NMR kahi hōʻailona nāwaliwali loa, kahi e maʻalahi ai i ka hoʻopilikia kūwaho. A ʻo kahi hopena, pono e hoʻolako pinepine ʻia nā ʻōnaehana MRI me nā pā Faraday (nā lumi pale) e hoʻokaʻawale i ka hoʻopilikia ʻana o ka RF kūwaho mai ke komo ʻana i ka ʻōnaehana. Eia nō naʻe, ʻoi aku ka maikaʻi o ka attenuation o ka pā Faraday no ka leki uila alapine, a ʻo ka hopena pale no ke alapine haʻahaʻa e kaupalena ʻia. ʻOi loa no ka hoʻonohonoho ʻana i nā ʻōnaehana MRI kokoke i nā subway, nā kaʻaahi, nā mea hoʻololi nui, nā ea, nā kaula hoʻoili uila, a pēlā aku. ʻAʻole pono e hoʻonohonoho ʻia ka cage Faraday, akā pono e hoʻonohonoho ʻia ka ʻōnaehana pale e hana i ka ʻōnaehana MRI i nā koina diagnostical. .

ʻO CSJ-ASH kahi hana pale pale uila hana kiʻekiʻe kiʻekiʻe i hoʻomohala ʻia e Ningbo Chuanshan Jia Electromekanical Co., Ltd. Hiki iā ia ke pale pono i nā māla electromagnetic DC, 50Hz / 60Hz mau pā uila uila pinepine ʻia e nā subway, nā kaʻaahi, nā kaʻaahi, nā kaula hoʻoili, nā pono hana hoʻohuli, nā ea hāpai, a pēlā aku. ʻO CSJ-ASH he ʻekolu mau mea nui: fluxgate probe kiʻekiʻe, hoʻokipa, a me nā pale pale. Hiki i ka ʻimi fluxgate kiʻekiʻe ke ʻike i ka hihia electromagnetic environment āpau Ma hope o ka hana ʻana, hoʻopuka ka mea hoʻokipa i kahi kaha huli e hāhai i ka manawa maoli, a ke hana nei ka mea i kēia manawa i kahi pā magnetic i loko o ka pale pale e hoʻopau ai i ka mākia magnet interrupt, no laila ke ʻike nei i ka pale hana o nā kahua electromagnetic haʻahaʻa haʻahaʻa.
