Umklamo kanye nokusetshenziswa kweamamotho angenasisekelokumathuluzi ezokwelapha kazibuthe (i-MRI) abaluleke kakhulu, ikakhulukazi ekuthuthukiseni ikhwalithi yezithombe, isivinini sokuskena nokunethezeka kwesiguli. I-Medical magnetic resonance ubuchwepheshe bokuthwebula obungahlanyisi obusetshenziswa kakhulu ekuxilongeni kwezokwelapha futhi bungahlinzeka ngesithombe sezicubu ezithambile ezinokulungiswa okuphezulu. Ukuze kuzuzwe ukuthwebula okusebenzayo nokusebenza, ingxenye ngayinye yensimbi kufanele ibe nokunemba okuphezulu nokuzinza, futhi i-coreless motor idlala indima ebalulekile kule nqubo.
Izidingo zokuklama
Kumathuluzi ezokwelapha kazibuthe resonance, ukuklama motors coreless idinga ukuhlangabezana nezidingo ezibalulekile ezimbalwa. Okokuqala, injini kufanele ibe nesivinini esikhulu sokujikeleza kanye nekhono lokulawula ukunemba okuphezulu ukuze kuqinisekiswe ukuthi indawo ehlobene yesampula (okungukuthi, isiguli) ingalungiswa ngokushesha nangokunembile ngesikhathi sokuthwebula. Isiguli sidinga ukuhlala sizinzile phakathi nenqubo yokuskena, futhi ukulawula okunembayo kwenjini kunganciphisa ngempumelelo ama-artifact anyakazayo futhi kuthuthukise ikhwalithi yokuthwebula.
Okwesibili, izinga lomsindo we-motor kufanele libe phansi ngangokunokwenzeka ukuze ugweme ukuphazamiseka kwesignali yokucabanga. Isignali yokuthwebula ephuma emshinini we-magnetic resonance wezokwelapha ngokuvamile ayinamandla kakhulu, futhi noma yimuphi umsindo owengeziwe ungabangela ukuhlanekezela noma ukulahlekelwa isignali. Ngakho-ke, ukudlidliza kanye nokuphazamiseka kazibuthe kagesi kwenjini kudinga ukucatshangelwa ngesikhathi sokuklanywa ukuze kuqinisekiswe ukuthi akunawo umthelela omubi kusiginali ngesikhathi sokusebenza.
Ngaphezu kwalokho, ubukhulu nesisindo samamotho angenasici nakho kubalulekile ekwakhiweni. Amathuluzi e-Medical resonance kazibuthe ngokuvamile adinga ukusebenza kahle endaweni elinganiselwe, ngakho umklamo ohlangene wenjini ungasindisa isikhala ngempumelelo futhi uthuthukise ukuhlanganisa konke kwethuluzi. Ngasikhathi sinye, ukukhethwa kwezinto zenjini nakho kubalulekile. Kumelwe ibe nokumelana okuhle kwezinga lokushisa kanye nezakhiwo ze-antimagnetic ukuze ivumelane nendawo yokusebenza yensimbi yezokwelapha kazibuthe resonance.
Izibonelo zohlelo lokusebenza
Ekusetshenzisweni okungokoqobo, ama-motor coreless asetshenziselwa ukunyakaza nokujikeleza kwemibhede yesiguli. Ngokulawula kahle ukunyakaza kombhede wesiguli, abacwaningi nodokotela bangaqinisekisa ukuthi indawo yesiguli ngesikhathi sokuskena inembile. Isibonelo, lapho uthwebula ubuchopho noma umgogodla, ukuma kwesiguli nesimo sakhe sithinta ngokuqondile ukucaca nokunemba kwesithombe. I-coreless motor inika amandla ukulungiswa kwesimo sombhede okusheshayo nokunembe, ngaleyo ndlela kuthuthukise ukusebenza kahle kokuskena nokuthembeka kwemiphumela.
Ngaphezu kwalokho, ama-motor coreless angasetshenziswa futhi ukulungisa ukufana kwendawo kazibuthe. Amandla esignali nokucaca kokuthwebula kwe-magnetic resonance kuhlobene eduze nokufana kwendawo kazibuthe. Ngokulungisa ukuzungezisa kwenjini, inkambu kazibuthe ingalungiswa kahle ukuze kuthuthukiswe umphumela wokuqoqwa kwesignali. Lawa mandla okulungisa abaluleke kakhulu kumathuluzi e-high-field medical magnetic resonance, lapho i-magnetic field inhomogeneities ezindaweni eziphakeme ingathinta kakhulu ikhwalithi yokucabanga.
Induduzo yesiguli
Ukunethezeka kwesiguli nakho kuwukucatshangelwa okubalulekile ekwakhiweni kwemishini ye-magnetic resonance yezokwelapha. Umsindo ophansi nezici zokudlidliza eziphansi ze-coreless motor zinganciphisa ngempumelelo ukungaphatheki kahle kwesiguli ngesikhathi sokuskena. Ngaphezu kwalokho, amandla enjini okuphendula ngokushesha afinyeza izikhathi zokuskena futhi anciphise isikhathi isiguli esisichitha ngaphakathi kwethuluzi, ngaleyo ndlela kuthuthukiswe isipiliyoni sesiguli sisonke.
Ukuthuthukiswa kwekusasa
Ngokuthuthuka okuqhubekayo kobuchwepheshe be-magnetic resonance yezokwelapha, izidingo zamamotho angenasici nazo zikhula njalo. Ngokuzayo, i-motor intelligence kanye ne-automation kuzoba umkhuba wokuthuthuka. Ngokwethula ama-algorithms okulawula okuthuthukile nobuchwepheshe bezinzwa, amamotho angenasisekelo angafinyelela ukuqapha nokulungiswa kwesikhathi sangempela okunembe kakhudlwana. Lokhu akuthuthukisi kuphela ukuzenzela kokuskena, kodwa futhi kunciphisa amaphutha abangelwa ukusebenza komuntu.
Ngaphezu kwalokho, ngokuthuthukiswa kwesayensi yezinto ezibonakalayo, ukusetshenziswa kwezinto ezintsha ezisebenza kahle kuzothuthukisa ukusebenza kwamamotho angenasisekelo. Isibonelo, ukusebenzisa izinto ezingasindi kanye namandla aphezulu kunganciphisa isisindo semoto futhi kuthuthukise isivinini sayo sokuphendula nokuzinza. Ngesikhathi esifanayo, ukusetshenziswa kwezinto ezisezingeni eliphansi ze-superconducting kungase futhi kunikeze izixazululo ezintsha zokulawulwa kwamandla kazibuthe wezinsimbi zezokwelapha ze-magnetic resonance.
Ekuphetheni
Kafushane, ukwakheka kanye nokusetshenziswa kwamamotho angenasici kumathuluzi ezokwelapha kazibuthe kuyisihloko esiyinkimbinkimbi nesibalulekile. Ngokuthuthukisa ukuklama nokulawula injini, ukusebenza kwethuluzi lezokwelapha likamagnetic resonance kungathuthukiswa kakhulu, ngaleyo ndlela kuthuthukiswe ukuthuthukiswa kwezithombe zezokwelapha. Ngokuthuthuka okuqhubekayo kobuchwepheshe,amamotho angenasisekeloizodlala indima ebaluleke kakhulu ekusetshenzisweni kwesikhathi esizayo kwe-magnetic resonance yezokwelapha.
