Uyilo kunye nokusetyenziswa kweiinjini ezingenasiphelokwizixhobo zonyango zemagnetic resonance (MRI) zibaluleke kakhulu, ngakumbi ekuphuculeni umgangatho womfanekiso, isantya sokuskena kunye nokuthuthuzela kwesigulane. I-resonance yemagnethi yonyango yitekhnoloji ye-imaging engeyiyo i-invasive esetyenziswa ngokubanzi kuxilongo lwezonyango kwaye inokubonelela nge-high-resolution soft tissue imaging. Ukuze kufezekiswe umfanekiso osebenzayo kunye nokusebenza, icandelo ngalinye lesixhobo kufuneka libe nokuchaneka okuphezulu kunye nokuzinza, kwaye i-motor coreless idlala indima ebalulekileyo kule nkqubo.
Iimfuno zoyilo
Kwizixhobo zonyango zemagnetic resonance, uyilo lweemoto ezingenasiphelo kufuneka zihlangabezane neemfuno eziphambili. Okokuqala, i-motor kufuneka ibe nesantya esiphezulu sokujikeleza kunye nobuchule bokulawula ukuchaneka okuphezulu ukuqinisekisa ukuba indawo ehambelanayo yesampuli (oko kukuthi, isigulane) inokukhawuleza kwaye ilungiswe ngokuchanekileyo ngexesha lokucinga. Isigulana kufuneka sihlale sizinzile ngexesha lenkqubo yokuskena, kwaye ulawulo oluchanekileyo lwemoto lunokunciphisa ngokufanelekileyo izinto ezishukumayo kunye nokuphucula umgangatho wokucinga.
Okwesibini, inqanaba lengxolo yemoto kufuneka libe liphantsi kangangoko kunokwenzeka ukuze ugweme ukuphazamiseka kwesignali yokucinga. Isiginali yomfanekiso osuka kumatshini wemagnethi yonyango idla ngokuba buthathaka kakhulu, kwaye nayiphi na ingxolo eyongezelelweyo inokubangela ukuphazamiseka okanye ukulahleka komqondiso. Ke ngoko, ukungcangcazela kunye nokuphazamiseka kwe-electromagnetic yemoto kufuneka kuthathelwe ingqalelo ngexesha loyilo ukuze kuqinisekiswe ukuba ayinayo impembelelo embi kumqondiso ngexesha lokusebenza.
Ukongeza, ubungakanani kunye nobunzima beemoto ezingenasiphelo nazo zibalulekile kuqwalaselo kuyilo. Izixhobo zemagnetic resonance zonyango zihlala zifuna ukusebenza ngokufanelekileyo ngaphakathi kwendawo encinci, ngoko ke uyilo oludibeneyo lwemoto lunokugcina ngokufanelekileyo indawo kwaye luphucule ukuhlanganiswa okupheleleyo kwesixhobo. Kwangaxeshanye, ukukhethwa kwezinto zenjini nako kubalulekile. Kufuneka ibe nokumelana nobushushu obulungileyo kunye neempawu ze-antimagnetic ukuziqhelanisa nendawo yokusebenza yesixhobo sonyango semagnetic resonance.
Imizekelo yesicelo
Kwizicelo ezisebenzayo, ii-motor coreless zisetyenziselwa ukunyakaza kunye nokujikeleza kweebhedi zesigulane. Ngokulawula ngokuchanekileyo ukuhamba kwebhedi yesigulane, abaphandi kunye noogqirha banokuqinisekisa ukuba indawo yesigulane ngexesha lokuskena ichanekile. Ngokomzekelo, xa ucinga ngengqondo okanye umqolo, ukuma kwesigulane kunye nesikhundla sichaphazela ngokuthe ngqo ukucaca kunye nokuchaneka kwemifanekiso. I-coreless motor yenza uhlengahlengiso olukhawulezayo noluchanekileyo lwendawo yebhedi, ngaloo ndlela iphucula ukusebenza kakuhle kokuskena kunye nokuthembeka kweziphumo.
Ukongeza, iimotor ezingenasiphelo zinokusetyenziselwa ukulungelelanisa ukufana kwendawo yamagnetic. Amandla omqondiso kunye nokucaca komfanekiso we-magnetic resonance imaging inxulumene ngokusondeleyo nokufana kwendawo yamagnetic. Ngokulungelelanisa ukujikeleza kwe-motor, i-magnetic field inokulungiswa kakuhle ukuze kuphuculwe umphumo wokuqokelela umqondiso. Oku kulungelelaniswa kwesakhono kubaluleke kakhulu kwizixhobo eziphezulu zonyango zemagnetic resonance, apho i-magnetic field inhomogeneities kwiindawo eziphakamileyo inokuchaphazela kakhulu umgangatho wokucinga.
Intuthuzelo yesigulane
Ukuthuthuzelwa kwesigulane kukwaqwalasela okubalulekileyo ekuyilweni koomatshini bonyango bemagnetic resonance. Ingxolo ephantsi kunye neempawu eziphantsi zokungcangcazela kwemoto engenasiphelo inokunciphisa ngokufanelekileyo ukungonwabi kwesigulana ngexesha lenkqubo yokuskena. Ukongeza, amandla okuphendula ngokukhawuleza kwemoto anciphisa amaxesha okuskena kwaye anciphise ixesha isigulane esichitha ngaphakathi kwesixhobo, ngaloo ndlela siphucula amava esigulane ngokubanzi.
Uphuhliso lwexesha elizayo
Ngokuqhubela phambili okuqhubekayo kwetekhnoloji ye-magnetic resonance yezonyango, iimfuno zeemoto ezingenasiphelo nazo zihlala zikhula. Kwixesha elizayo, ubukrelekrele bemoto kunye ne-automation iya kuba yindlela yophuhliso. Ngokuzisa i-algorithms yolawulo oluphezulu kunye netekhnoloji ye-sensor, iimotor ezingenasiphelo zinokufezekisa ujongo oluchanekileyo lwexesha lokwenyani kunye nohlengahlengiso. Oku akuphuculi nje ukuzenzekelayo kokuskena, kodwa kunciphisa iimpazamo ezibangelwa yimisebenzi yabantu.
Ukongeza, ngophuhliso lwesayensi yezinto eziphathekayo, ukusetyenziswa kwezinto ezintsha zokusebenza okuphezulu kuya kuphucula ngakumbi ukusebenza kweemoto ezingenasiphelo. Ngokomzekelo, ukusebenzisa izinto ezilula kunye namandla aphezulu kunokunciphisa ubunzima bemoto kunye nokuphucula isantya sokuphendula kunye nokuzinza. Kwangaxeshanye, ukusetyenziswa kwezixhobo zobushushu obuphantsi obuphezulu kunokubonelela ngezisombululo ezitsha zolawulo lwemagnethi yezixhobo zonyango zemagnetic resonance.
Ukuququmbela
Isishwankathelo, uyilo kunye nokusetyenziswa kwee-motor coreless kwizixhobo zonyango zemagnetic resonance yisihloko esinzima kwaye esibalulekileyo. Ngokulungisa uyilo kunye nokulawulwa kwemoto, ukusebenza kwesixhobo semagnetic resonance yonyango kunokuphuculwa kakhulu, ngaloo ndlela kukhuthaze uphuhliso lwemifanekiso yonyango. Ngenkqubela phambili eqhubekayo yetekhnoloji,iinjini ezingenasipheloiya kudlala indima ebaluleke ngakumbi kwizicelo zexesha elizayo lemagnetic resonance yonyango.
