Umklamo kanye nokusetshenziswa kweama-motor angenasisekeloEzintweni zokwelashwa ze-magnetic resonance (MRI) zibaluleke kakhulu, ikakhulukazi ekuthuthukiseni ikhwalithi yezithombe, isivinini sokuskena kanye nenduduzo yesiguli. I-medical magnetic resonance ubuchwepheshe bokuthwebula izithombe obungangenisi umswakama obusetshenziswa kabanzi ekuxilongweni kwezokwelapha futhi bunganikeza izithombe zezicubu ezithambile ezinesinqumo esiphezulu. Ukuze kufezwe izithombe nokusebenza okuphumelelayo, ingxenye ngayinye yethuluzi kumele ibe nokunemba okuphezulu kanye nokuqina, futhi injini engenamgogodla idlala indima ebalulekile kule nqubo.
Izidingo zomklamo
Ezinsimbini ze-magnetic resonance zezokwelapha, ukwakheka kwama-motor angenawo umgogodla kudinga ukuhlangabezana nezidingo eziningana ezibalulekile. Okokuqala, injini kumele ibe nesivinini esikhulu sokujikeleza kanye namakhono okulawula anembile ukuqinisekisa ukuthi indawo ehlobene yesampula (okungukuthi, isiguli) ingalungiswa ngokushesha nangokunembile ngesikhathi sokuthwebula izithombe. Isiguli sidinga ukuhlala sizinzile ngesikhathi senqubo yokuskena, futhi ukulawulwa okunembile kwenjini kunganciphisa ngempumelelo izinto zokunyakaza futhi kuthuthukise ikhwalithi yokuthwebula izithombe.
Okwesibili, izinga lomsindo wemoto kumele libe phansi ngangokunokwenzeka ukuze kugwenywe ukuphazamiseka kwesignali yesithombe. Isignali yesithombe evela emshinini we-magnetic resonance wezokwelapha ivame ukuba buthaka kakhulu, futhi noma yimuphi umsindo owengeziwe ungabangela ukuphazamiseka noma ukulahleka kwesignali. Ngakho-ke, ukudlidliza kanye nokuphazamiseka kwe-electromagnetic kwemoto kudingeka kucatshangelwe ngesikhathi sokuklama ukuqinisekisa ukuthi ayinawo umthelela omubi esignalini ngesikhathi sokusebenza.
Ngaphezu kwalokho, ubukhulu nesisindo sama-motor angenawo umgogodla nakho kubalulekile ekuklanyweni. Izinsimbi zokukhanya ze-magnetic resonance zezokwelapha ngokuvamile zidinga ukusebenza kahle ngaphakathi kwesikhala esilinganiselwe, ngakho-ke ukwakheka okuhlangene kwenjini kungonga isikhala ngempumelelo futhi kuthuthukise ukuhlanganiswa okuphelele kwensimbi. Ngesikhathi esifanayo, ukukhethwa kwezinto zemoto nakho kubalulekile. Kumelwe ibe nokumelana okuhle nokushisa kanye nezakhiwo zokulwa nogesi ukuze ivumelane nendawo yokusebenza yensimbi yokukhanya ye-magnetic resonance yezokwelapha.
Izibonelo zohlelo lokusebenza
Ezisetshenzisweni ezisebenzayo, ama-motor angenamgogodla asetshenziswa kakhulu ekunyakazeni nasekujikeleziseni imibhede yesiguli. Ngokulawula ngokunembile ukunyakaza kombhede wesiguli, abacwaningi nodokotela bangaqinisekisa ukuthi indawo yesiguli ngesikhathi sokuskena inembile. Isibonelo, lapho kuthwetshulwa ubuchopho noma umgogodla, ukuma kwesiguli kanye nendawo kuthinta ngqo ukucaca nokunemba kwesithombe. I-motor engenamgogodla ivumela ukulungiswa kwesimo sombhede okusheshayo nokunembile, ngaleyo ndlela kuthuthukiswe ukusebenza kahle kokuskena kanye nokuthembeka kwemiphumela.
Ngaphezu kwalokho, ama-motor angenawo umgogodla angasetshenziswa futhi ukulungisa ukufana kwensimu yamagnetic. Amandla esignali kanye nokucaca kwe-magnetic resonance imaging kuhlobene kakhulu nokufana kwensimu yamagnetic. Ngokulungisa ukujikeleza kwenjini, insimu yamagnetic ingalungiswa kahle ukuze kuthuthukiswe umphumela wokuqoqwa kwesignali. Leli khono lokulungisa libaluleke kakhulu kumathuluzi e-magnetic resonance ezokwelapha aphezulu, lapho ukungalingani kwensimu yamagnetic ezindaweni eziphakeme kungathinta kakhulu ikhwalithi yesithombe.
Induduzo yesiguli
Induduzo yesiguli nayo iyinto ebalulekile ekucatshangweni ekwakhiweni kwemishini yezokwelapha ye-magnetic resonance. Umsindo ophansi kanye nezici zokudlidliza eziphansi zenjini engenamgogodla kunganciphisa ngempumelelo ukungakhululeki kwesiguli ngesikhathi senqubo yokuskena. Ngaphezu kwalokho, ikhono lokuphendula ngokushesha lenjini lifinyeza izikhathi zokuskena futhi linciphise isikhathi isiguli esisichitha ngaphakathi kwethuluzi, ngaleyo ndlela kuthuthukiswe ulwazi lwesiguli sonke.
Intuthuko yesikhathi esizayo
Ngokuthuthuka okuqhubekayo kobuchwepheshe be-magnetic resonance yezokwelapha, izidingo zama-motor angenawo umgogodla nazo ziyanda njalo. Esikhathini esizayo, ubuhlakani bezimoto kanye nokwenza izinto ngokuzenzakalela kuzoba yindlela yokuthuthuka. Ngokwethula ama-algorithms okulawula athuthukile kanye nobuchwepheshe bezinzwa, ama-motor angenawo umgogodla angafinyelela ukuqapha nokulungisa okunembile ngesikhathi sangempela. Lokhu akugcini nje ngokuthuthukisa ukuzenzekela kokuskena, kodwa futhi kunciphisa amaphutha abangelwa ukusebenza kwabantu.
Ngaphezu kwalokho, ngokuthuthukiswa kwesayensi yezinto ezibonakalayo, ukusetshenziswa kwezinto ezintsha ezisebenza kahle kuzothuthukisa kakhulu ukusebenza kwama-motor angenawo umgogodla. Isibonelo, ukusebenzisa izinto ezilula nezinamandla aphezulu kunganciphisa isisindo semoto futhi kuthuthukise isivinini sayo sokuphendula kanye nokuqina. Ngesikhathi esifanayo, ukusetshenziswa kwezinto ezisebenzisa amazinga aphezulu okushisa kungaphinde kunikeze izixazululo ezintsha zokulawulwa kwamandla kazibuthe ezinsimbini zokwelapha ze-magnetic resonance.
Ekuphetheni
Ngamafuphi, ukwakheka nokusetshenziswa kwama-motor angenawo umgogodla ezinsimbini ze-magnetic resonance zezokwelapha kuyisihloko esiyinkimbinkimbi nesibalulekile. Ngokwenza ngcono ukwakheka nokulawulwa kwemoto, ukusebenza kwensimbi ye-magnetic resonance yezokwelapha kungathuthukiswa kakhulu, ngaleyo ndlela kukhuthazwe ukuthuthukiswa kwezithombe zezokwelapha. Ngokuthuthuka okuqhubekayo kobuchwepheshe,ama-motor angenasisekeloizodlala indima ebaluleke kakhulu ekusetshenzisweni kwe-magnetic resonance yezokwelapha esikhathini esizayo.
