Iindlela Zokufota Ngonyango Eziye Zasitsala Ingqalelo

Apha, siza kujonga ngokufutshane iindlela ezintathu eziphucula ubuchwephesha bokufota ngezonyango, kwaye ngenxa yoko, ukuxilongwa, iziphumo zesigulana, kunye nokufikeleleka kwezempilo. Ukuze sibonise ezi ndlela, siza kusebenzisa i-magnetic resonance imaging (I-MRI), esebenzisa imiqondiso yerediyo (RF).

Iingcali zonyango zixhomekeke kwiindlela ezahlukeneyo zokuthatha imifanekiso yezonyango ukuze zijonge izakhiwo zomzimba kunye nemisebenzi yazo ngaphandle kokungenelela. Ezi ndlela ziluncedo ekuxilongeni izifo kunye nokwenzakala, ukujonga ukusebenza kakuhle konyango, kunye nokucwangcisa iinkqubo zotyando. Indlela nganye yokwenza imifanekiso yenzelwe ukusetyenziswa kwezonyango ezithile.

Ukudibanisa Iindlela Zokufota

Iitekhnoloji zemifanekiso exutyiweyo zisebenzisa amandla okudibanisa iindlela ezahlukeneyo ukuvelisa imibono eneenkcukacha ezininzi ngomzimba. Iingcali zonyango zisebenzisa ezi mifanekiso ukuphucula ukuxilongwa kunye nonyango lwezigulane.

Umzekelo, ii-scan ze-PET/MRI zidibanisa ii-scan ze-positron emission tomography (PET) kunye nee-scan ze-MRI. I-MRI inika imifanekiso eneenkcukacha zezakhiwo zomzimba zangaphakathi kunye nemisebenzi yazo, ngelixa i-PET ichonga izinto ezingaqhelekanga kusetyenziswa ii-tracers. Olu xube luluncedo kakhulu kunyango lweemeko ezifana nesifo sika-Alzheimer, isifo sokuwa, kunye neethumba zobuchopho. Ngaphambili, ukudibanisa i-PET kunye ne-MRI bekungenakwenzeka ngenxa yeemagnethi ezinamandla ze-MRI eziphazamisana nezixhobo zokubona imifanekiso ze-PET. Ii-scan kwakufuneka zenziwe ngokwahlukeneyo zize emva koko zidityaniswe, kubandakanya ukucutshungulwa kwemifanekiso okuntsonkothileyo kunye nokulahleka kwedatha okunokwenzeka. Ngokutsho kweStanford Medicine, indibaniselwano ye-PET/MRI ichaneke ngakumbi, ikhuselekile, kwaye ilula ngakumbi kunokwenza ii-scan ezahlukeneyo.

Ukwandisa Ukusebenza kweNkqubo yokuFota

Ukuphuculwa Kokusebenza kubangela ukuba umfanekiso uphuculwe kunye nolwazi oluchanekileyo ngeenjongo zokuxilonga kunye nonyango. Umzekelo, abaphandi ngoku banokufikelela kwiinkqubo ze-MRI ezinamandla entsimi ukuya kuthi ga kwi-7T. Olu phuculo lokusebenza luphucula umlinganiselo wesignali-kwingxolo (SNR), nto leyo ekhokelela kwiziphumo zomfanekiso ezicacileyo nezineenkcukacha. Kukwakho nomdla wokwenza ii-MRI receivers zijolise ngakumbi kwidijithali. Ngokufumaneka kwesisombululo esiphezulu kunye nee-converters eziphezulu ze-analog-to-digital (ADCs), kukho ithuba lokutshintshela i-ADC kwi-RF coil, enokunciphisa ingxolo kwaye yonyuse i-SNR xa ukusetyenziswa kwamandla kulawulwa ngokufanelekileyo. Iingenelo ezifanayo zinokufunyanwa ngokongeza ii-RF coils ezininzi kwinkqubo. Ukubeka phambili ukuphuculwa kokusebenza kuthetha ukuphucula izinto zamava esigulana ezifana namaxesha okuskena kunye neendleko.

Ukuyila Izixhobo Zokuthwebula Izinto Eziphathekayo

Ngokwendlela eyilwe ngayo, ezinye izixhobo zovavanyo kunye nonyango lwezigulane zaqala kwiindawo ezilawulwayo ukuze zisebenze kakuhle (umz., i-MRI suite).

I-tomography ebalwe ngekhompyutha (CTkunyeumfanekiso we-magnetic resonance (I-MRI) yimizekelo emihle kakhulu.

Nangona ezi ndlela zokuthatha imifanekiso zisebenza kakuhle ekuxilongeni izifo, zinokuba nzima kakhulu emzimbeni kwizigulana ezigula kakhulu. Uphuhliso lwetekhnoloji ngoku luhambisa ezi nkonzo zokuxilonga ziye apho zikhoyo izigulana.

Xa kufikwa kwizixhobo ezihlala zinganyakazi ezifana noomatshini be-MRI, ukudala uyilo lokuphatheka lula kubandakanya ukuthathela ingqalelo izinto ezifana nobukhulu nobunzima, amandla, amandla emagnethi, iindleko, umgangatho womfanekiso, kunye nokhuseleko. Kwinqanaba lezinto, ukhetho olufana nee-capacitors ezisebenzayo kakhulu zidlala indima ebalulekileyo ekuqinisekiseni ukuveliswa kwamandla okuzinzileyo nokusebenzayo kunye nokucutshungulwa kwemiqondiso ngaphakathi kwesakhelo esincinci nesiphathekayo.

Ngophuhliso lwetekhnoloji yemifanekiso yezonyango, kuvela iinkampani ezininzi ezinokubonelela ngeemveliso zemifanekiso, ezinje ngee-injectors kunye neesirinji. Itekhnoloji yezonyango ye-LnkMed yenye yazo. Sinikezela ngepotifoliyo epheleleyo yeemveliso zoxilongo ezincedisayo:Ii-CT injectors，Inaliti ye-MRIkwayeI-DSA injectorZisebenza kakuhle neentlobo ngeentlobo ze-CT/MRI scanner ezifana ne-GE, iPhilips, iSiemens. Ngaphandle kwe-injector, sikwabonelela ngesirinji kunye netyhubhu esetyenziswa kwiintlobo ezahlukeneyo ze-injector kuqukaIMedrad/Bayer, IMallinckrodt/Guerbet, I-Nemoto, I-Medtron, U-Ulrich.

Nazi izinto esiziqinisayo: amaxesha okuhambisa ngokukhawuleza; Iziqinisekiso ezipheleleyo zokuqinisekiswa, iminyaka emininzi yamava okuthumela ngaphandle, inkqubo yokuhlolwa komgangatho ogqibeleleyo, iimveliso ezisebenzayo ngokupheleleyo.
