Mu makina ojambulira a MRI, ntchito ya koyilo ya gradient makamaka ndikuzindikira ma encoding apakati. Mukasanthula chithunzicho, makholo a X, Y, ndi Z anjira zitatu amagwirira ntchito limodzi kusankha magawo, ma encoding pafupipafupi ndi encoding ya magawo motsatana. Mphamvu ikadutsa pamakoyilowa, gawo lachiwiri la maginito limapangidwa. Gawo la gradient iyi limasokoneza pang'ono gawo lalikulu la maginito mwanjira yodziwikiratu, kupangitsa kuti ma frequency a resonance a ma protoni asinthe mosiyanasiyana monga momwe amagwirira ntchito. Ntchito yayikulu ya ma gradients, chifukwa chake, ndikulola kusungitsa kwapakati kwa chizindikiro cha MR. Mapiritsi a gradient amafunikiranso panjira zingapo za "physiologic", monga MR angiography, diffusion, ndi perfusion imaging.

Nthawi yomweyo, coil ya gradient imakhalanso ndi udindo pakugwira ntchito kwa shimming ndi anti-eddy pano.

Kampani yathu imapereka ma coil a flatplate gradient okhala ndi magwiridwe antchito abwino, omwe amatha kukwaniritsa zosowa zogwiritsidwa ntchito.

Kuchokera pamawonekedwe ake, chowongolera chopanda phokosochi chili ndi ma X, Y, Z anjira zitatu zolumikizira, zosavuta kulumikizana, ndipo zimatha kukhala ndi makina oziziritsira madzi, omwe amatha kuziziritsa koyilo ya gradient ndikupanga chithunzicho. wokhazikika kwambiri;

Itha kupangidwanso ngati koyilo yotchinga yotetezedwa kuti ichepetse mphamvu ya eddy kuchokera kugwero. Chifukwa njira yabwino kwambiri yothanirana ndi mafunde a eddy ndikuletsa kubadwa kwa mitsinje ya eddy poyamba. Ichi ndi chilimbikitso chopanga zodzitchinjiriza (zodzitchinjiriza) zokhazikika; yapano mu koyilo yotchinga imagwiritsidwa ntchito kuthamangira kosiyana ndi koyilo yojambula kuti muchepetse mafunde a eddy. Koyilo ya gradient yopangidwa motere ndi yodalirika komanso yolimba.
