I-Magnetic resonance imaging (MRI) ingenye yamasu abaluleke kakhulu wezokwelapha namuhla. Isebenzisa amasimu aqinile kazibuthe kanye nama-radiofrequency pulses ukuze angazitholi izithombe eziphakeme kakhulu zesigaba sesicubu somuntu, edlala indima ebalulekile ekuhlolweni kwezifo eziningi. Kodwa-ke, izikena zendabuko ze-MRI zinesakhiwo esivalekile, ukuphoqa iziguli ukuthi ziqambe amanga emhubheni omncane ngesikhathi sokuskena. Lokhu kudala ukucindezelwa okukhulu kwengqondo, ikakhulukazi izingane, abadala, kanye neziguli ezine-claustrophobia, njengoba zilele emhubheni obizayo zingakhululeka kakhulu. Ngaphezu kwalokho, umsindo omkhulu ukhiqizwa ngokuqhubekayo ngesikhathi se-MRI Scans, ungezelela ekungaphatheki kahle kweziguli. Ngakho-ke, ukuvula izikena ze-MRI zathuthukiswa ukuthuthukisa kakhulu isipiliyoni seziguli.
Isici esikhulu kunazo zonke se-Open MRI kunguzibuthe wayo omise okwenziwe yi-C noma o Iziguli zibekwe ekuvulekeni ukuze zibone imvelo yangaphandle esikhundleni sokuvalelwa endaweni emincane. Lokhu kudambisa kakhulu ukukhathazeka kweziguli nemizwa yokuvalelwa. Ngaphezu kwalokho, ukufinyelela okuvulekile kwe-MRI kukhiqiza kuphela ama-decibels acishe abe ngu-70 womsindo, ukwehliswa okungama-40% kusuka kuma-decibels angama-110 e-MRI scanners yendabuko, evumela inqubo yokuskena eboshelwe ngokwengeziwe.

Ngokuya kwezakhi zohlelo, vula i-MRI igcina izingxenye eziyinhloko zesithwebuli esijwayelekile se-MRI, kufaka phakathi izibuthe eziphambili ezikhiqiza amandla amakhulu kazibuthe aqinile, amakhoyili akhiqizwayo akhiqiza amasimu akhiqizwayo, kanye namakhoyili we-RF okutholwa kwesiginali nokutholwa kwesiginali. Amandla enkambu wokuzibuthe okuyinhloko e-Open MRI asafinyelela ku-0,2 kuye ku-3 tesla, e-PAR ene-MRI ejwayelekile. Vula i-MRI futhi ifaka nezinhlaka ezengeziwe zokusekelwa kweziguli nezinqubo zokuhlanza ukuze kuhlaliswe izidingo ezivulekile zokuhlelwa kanye nezidingo zokubeka iziguli. Sekukonke, ngenkathi kuthuthukisa ulwazi lwesiguli, vula i-MRI igcina imigomo eyisisekelo ye-Magnetic Resonance imaging futhi isenganikeza izithombe ezisezingeni eliphakeme zezicubu zomuntu.
Uma kuqhathaniswa ne-MRI eboshwe ngendabuko ye-MRI, i-Open MRI inezinzuzo ezilandelayo ezilandelayo:
1. Kunciphisa kakhulu ukwesaba kwe-claustrophobic. Idizayini evulekile iqinisekisa iziguli azizizwa zivalelwe ngaphakathi emhubheni omncane, ukuhlinzeka indawo yokuzolisa ikakhulukazi ezinganeni, asebekhulile, noma iziguli ze-claustrophobic. Lokhu kuthuthukisa ukuhambisana futhi kuvumela ukutholwa kwezikena ezisezingeni eliphakeme.
2. Yehlisa umsindo omkhulu, ukuvumela ukuskena okunethezekile. Amazinga we-Open Noitoaine acishe abe ngu-40% aphansi kunezinhlelo ezivalekile. Umsindo oncishisiwe unciphise ukukhathazeka ngesineke, okuvumela izikhathi ezinde zokuhlola kanye nokutholwa okuningiliziwe kokucabanga.
3. Iguquguqukayo futhi ifinyeleleke kuzo zonke iziguli. Ukufinyelela okuvulekile kanye nomsindo oncishisiwe kwenza ukuhlolwa kube lula kubasebenzisi besihlalo esinamasondo, iziguli ze-syllet, noma labo abanobunzima bokuhamba. Ukuvula izikena ze-MRI kungaskena iziguli ngqo ngaphandle kokudluliselwa okucindezelayo ngokomzimba nangokwengqondo.
4. Inika amandla izinhlelo zokusebenza zokuhlanganisa. Idizayini evulekile inikeza ukufinyelela okulula ezigulini ngesikhathi sokuskena, okwenza izinqubo zokungenelela eziqondiswa yi-MRI. Odokotela bangasebenza ezigulini ngesikhathi sangempela ngenkathi becabanga ngokuqhubekayo indawo yokwelashwa.
Kunemikhawulo ethile ye-Open MRI ngokuqhathaniswa nezinhlelo ezivalekile:
1. Ikhwalithi yesithombe ingahle iphansi kancane, ikakhulukazi ekuhlukanisweni kwezicubu ezithambile nesinqumo. Idizayini evulekile isho amandla kazibuthe anobuhlakani obukhulu kunamasilinda endabuko avalekile, okuholela ekulinganiseni kwe-gradient kwezomnotho kanye nokulungiswa kwesithombe sokugcina esiphansi. Lokhu kuvelele ikakhulukazi esihlahleni esiphansi se-MRI esisezingeni eliphansi. I-Stroer 1.5T noma i-3T evulekile Scanners inganxephezela i-inhomogeneity yensimu enomklamo wokulandelana okuthuthukile kanye nokulandelana. Kepha ngokweqiniso, amasilinda avalekile anikela njalo amasimu anele futhi anezinkulungwane.
2 Iziguli ezikhuluphele zinevolumu enkulu yomzimba, kanye nemizabalazo evulekile yokugcina ukulondolozwa kwendawo yamandla kazibuthe ye-homogeneous phezu kwawo. Isikena sendabuko esivalelekile se-MRI sidinga kuphela ukwandisa i-homogeneity yasensimini emkhathini omncane we-cylindrical isikhala, efinyelela imiphumela engcono yeziguli ezinkulu. Kepha abathengisi be-MRI basebenza ngezixazululo ezenziwe ngokwezifiso ezinjengokuvuleka kweziguli ezibanzi namandla enkundla anamandla ukubhekana nalo mkhawulo.
I-3. Isakhiwo esiyinkimbinkimbi esiholela ezindlekweni eziphakeme zokuthenga nokulungisa. Idizayini evulekile idinga uzibuthe okuyinkimbinkimbi kakhulu kanye nama-gradient coil geometries, kanye nezinhlelo ezenziwe ngezifiso zokuphatha iziguli. Lokhu kukhuphuka kobunzima bokwakha kuhumushela ezindlekweni eziphakeme zokuqala kuqhathaniswa nama-cylindrical magrets afakiwe ama-cylindrical magrets alinganayo enkambu yamandla ensimu. Ngaphezu kwalokho, ukwakheka okungajwayelekile kwama-open magnets we-MRI kubenza bahlukunyezwe isiza ngaphakathi kwengqalasizinda ekhona yesibhedlela eyenzelwe ama-MRI BEORS. Ukugcinwa kwesikhathi eside kanye nokugcwaliswa kwe-helium nakho kudlalwa imali ngenxa yemvelo yangokwezifiso yezinhlelo ezivulekile ze-MRI. Kepha ezigulini ezizuza kakhulu emklamweni ovulekile, lezi zindleko ezengeziwe zingahle zilungiswe.
Ngamafuphi, abakwa-Open Architecture Mnu Scanners banqobe ubuthakathaka bemibhalo yendabuko yendabuko yendabuko futhi ithuthukisa kakhulu induduzo yesiguli nokwamukelwa kweziguli. Banikeza indawo enobungane yokuskena ezuza iziguli eziningi. Ngentuthuko eqhubekayo, ukuvula i-MRI kuzothola ukusetshenziswa okubanzi kwemitholampilo, ikakhulukazi ukuthola iziguli ezikhathazayo, zezingane, ezikhulile nezikhulile.
