Kwakira Igiceri
Muri sisitemu ya MRI, igiceri cyakira nikintu cyingenzi, kigira ingaruka itaziguye kumiterere yishusho. Kwakira ibishishwa bishinzwe kumenya ibimenyetso bya MR. Urusaku runyeganyega rwa neti rukuruzi ruva muri sisitemu ishimishije irashobora gufatwa na coil ikoreramo amashanyarazi. Ibiriho noneho byongerewe, bikabikwa, kandi byungururwa kugirango bikuremo inshuro namakuru yicyiciro.
Nyuma yimyaka myinshi yubushakashatsi budacogora nakazi gakomeye, itsinda ryacu R&D ryateje imbere igiceri cyaryo cyakira binyuze mubizamini bitandukanye no kugereranya, kandi ibipimo byerekana imikorere byageze ku rwego rwo hejuru mu nganda.
Dufite ubwoko bwinshi bwo kwakira ibishishwa byo guhitamo, bishobora gutondekwa ukurikije isura, ishobora kugabanywa hejuru, hejuru yinyoni, hamwe na transceiver coil. Mubyongeyeho, uyikoresha arashobora guhitamo umubare wimiyoboro ya coil nkuko bikenewe,
Mubisanzwe, ibishishwa byinyoni nibyo bikoreshwa cyane, kandi birashobora gukoreshwa kumutwe, ijosi, ivi, nibindi.; kurugero, imiyoboro ibiri yinyoni igizwe na solenoid coil hamwe na coiffe. Ibiceri byacu bifite ibintu byiza kandi bihuje neza, Birashobora guhuza ibikenerwa bitandukanye byo gusikana, mugihe kimwe, tunatanga serivisi zabigenewe, abakoresha barashobora guhitamo ingano bonyine.
Igiceri cyo hejuru kirashobora gukoreshwa mugusuzuma umugongo cyangwa ibindi bice byinyungu; mugihe ukoresheje coil yo hejuru, kubera gufungura kwayo, urashobora gusikana agace k'inyungu muburyo butandukanye.
Igiceri cya transceiver ni ubwoko bushya bwa coil. Ihererekanyabubasha ryayo hamwe no kwakirwa byahujwe, bityo ubunini bwa coil ni buto kuruta ibisanzwe. Mubihe bimwe, ugereranije na sisitemu ya transceiver gakondo yatandukanijwe, ifite ibisabwa bito ku mbaraga za amplifier ya RF. Mubyongeyeho, bitewe nubunini bwacyo, ntibisaba ubunini bunini bwa magneti, kandi birashobora gukoreshwa kuri sisitemu ntoya cyangwa izindi sisitemu zifite umwanya uhagije usabwa.
