Kwi-MRI scan system, umsebenzi wekhoyili yegradient ikakhulu kukuqonda ukukhowudwa kwendawo. Xa uskena umfanekiso, i-X, Y, kunye no-Z iikhoyili zeendlela ezintathu zodidi lwemitha zisebenza kunye ukwenza ukhetho lwesilayi, ukufakwa kweekhowudi rhoqo kunye nokufakwa kweekhowudi ngokulandelelanayo. Xa i-current idluliswa kwezi khoyili i-second magnetic field yenziwa. Lo mmandla wokuthambeka ugqwetha kancinane indawo yemagnethi ephambili kwipateni eqikelelwayo, ibangela ukuba iresonance frequency yeprotons yahluke njengomsebenzi wendawo. Umsebenzi ophambili weegradient, ke ngoko, kukuvumela ukufakwa kwekhowudi yendawo yesiginali ye-MR. Iikhoyili zegradient zikwabalulekile kuluhlu olubanzi lweendlela ze "physiologic", ezinje ngeMR angiography, diffusion, kunye ne-perfusion imaging.

Ngexesha elifanayo, i-coil ye-gradient nayo inoxanduva lomsebenzi we-shimming kunye ne-anti-eddy yangoku.

Inkampani yethu ibonelela ngeekhoyili ze-flat-plate gradient ngokusebenza kakuhle, ezinokuhlangabezana neemfuno zokusetyenziswa.

Ukusuka kwimbono yesakhiwo, le platifomu ye-gradient ine-X, Y, Z yeendlela ezintathu zeekhoyili ze-gradient, kulula ukudibanisa, kwaye inokuxhotyiswa ngenkqubo yokupholisa amanzi, enokuthi ipholise ngokufanelekileyo ikhoyili ye-gradient kwaye yenze umfanekiso. uzinze ngakumbi;

Isenokwenziwa kwakhona njengekhoyili ekhuselweyo yegradient ukuze inciphise ngakumbi i-eddi yangoku evela kumthombo. Ngenxa yokuba eyona ndlela isebenzayo yokulawula imisinga ye-eddy kukuthintela ukuveliswa kwee-eddy currents kuqala. Le yinkuthazo yokuphuhlisa izikhuselo ezisebenzayo (ukuzikhusela) iigradient; i-current in the shielding coil isetyenziselwa ukubaleka kwicala elichaseneyo ne-imaging gradient coil ukunciphisa imisinga yeeddy. Ikhoyili ye-gradient eyenziwe ngolu hlobo inokwethenjelwa kwaye iqinile.
