I ka ʻōnaehana scan MRI, ʻo ka hana o ka gradient coil ka mea nui e ʻike i ka encoding spatial. I ka nānā ʻana i ke kiʻi, hana pū ka X, Y, a me Z ʻekolu-ala gradient coils e hana i ke koho ʻāpana, ka hoʻopili alapine a me ka hoʻopā ʻana i ka pae. Ke hele ʻia ke au i loko o kēia mau wili, hana ʻia kahi māla magnetic lua. Hoʻololi iki kēia māla gradient i ka māla magnetic nui i kahi ʻano wānana, e hoʻololi i ka pinepine resonance o nā protons ma ke ʻano he kūlana. ʻO ka hana nui o nā gradients, no laila, ʻo ia ka ʻae ʻana i ka hoʻopā ʻana o ka hōʻailona MR. He mea koʻikoʻi nō hoʻi nā coils gradient no ka nui o nā ʻenehana "physiologic", e like me MR angiography, diffusion, a me ke kiʻi perfusion.

I ka manawa like, ʻo ka gradient coil ke kuleana no ka hana o ka shimming a me ka anti-eddy current

Hāʻawi kā mākou hui i nā coils gradient flat-plate me ka hana maikaʻi, hiki ke hoʻokō i nā pono o ka hoʻohana.

Mai kahi hiʻohiʻona o ka hiʻohiʻona, loaʻa i kēia gradient pālahalaha ʻo X, Y, Z ʻekolu mau ʻāpana gradient, maʻalahi e hoʻopili, a hiki ke hoʻolako ʻia me kahi ʻōnaehana hoʻoheheʻe wai, hiki ke hoʻomaha maikaʻi i ka coil gradient a hana i ke kiʻi. ʻoi aku ka paʻa;

Hiki ke hoʻolālā ʻia ma ke ʻano he coil gradient pale ikaika e hōʻemi hou i ka eddy au mai ke kumu. No ka mea, ʻo ke ala maikaʻi loa e hoʻomalu ai i nā au eddy, ʻo ia ka pale ʻana i ka hana mua ʻana o nā au eddy. ʻO kēia ke kumu hoʻoikaika e hoʻomohala i nā gradients pale ikaika (self-shielding); hoʻohana ʻia ke au i loko o ka wili pale e holo ma ka ʻaoʻao ʻē aʻe i ka coil gradient kiʻi e hōʻemi i nā au eddy. ʻO ka gradient coil i hana ʻia ma kēia ʻano he hilinaʻi a paʻa.
