Izikena ze-Computed Tomography (CT) zingamathuluzi okuthwebula izithombe athuthukisiwe ahlinzeka ngezithombe ezinemininingwane yezakhiwo zangaphakathi zomzimba. Zisebenzisa ama-X-ray kanye nobuchwepheshe bekhompyutha, le mishini idala izithombe ezinezingqimba noma "izingcezu" ezingahlanganiswa zibe umfanekiso we-3D. Inqubo ye-CT isebenza ngokuqondisa imisebe ye-X-ray emzimbeni kusuka kuma-engeli amaningi. Le misebe itholwa yizinzwa ezikwelinye icala, bese idatha icutshungulwa yikhompyutha ukuze ikhiqize izithombe ezinesinqumo esiphezulu zamathambo, izicubu ezithambile, kanye nemithambo yegazi. Ukuthwebula izithombe ze-CT kubalulekile ekuxilongeni izimo eziningi zezokwelapha, kusukela ekulimaleni kuya kumdlavuza, ngenxa yamandla ayo okuhlinzeka ngezithombe ezicacile nezinemininingwane ze-anatomy yangaphakathi.
Ama-CT scanner asebenza ngokulalisa isiguli etafuleni elinenjini elihamba liye kudivayisi enkulu eyindilinga. Njengoba ithubhu le-X-ray lijikeleza isiguli, ama-detector athwebula ama-X-ray adlula emzimbeni, abese eguqulwa abe izithombe ngama-algorithms ekhompyutha. Lo msebenzi uyashesha futhi awuhlaseli, kanti ama-scan amaningi aqedwa ngemizuzu embalwa. Intuthuko ebalulekile kubuchwepheshe be-CT, njengesivinini sokuthwebula izithombe esisheshayo kanye nokwehla kokuvezwa kwemisebe, iyaqhubeka nokuthuthukisa ukuphepha kwesiguli kanye nokusebenza kahle kokuxilonga. Ngosizo lwama-CT scanner anamuhla, odokotela bangenza i-angiography, i-colonoscopy ebonakalayo, kanye ne-cardiac imaging, phakathi kwezinye izinqubo.
Imikhiqizo ehamba phambili emakethe ye-CT scanner ifaka phakathi i-GE Healthcare, i-Siemens Healthineers, i-Philips Healthcare, kanye ne-Canon Medical Systems. Ngayinye yale mikhiqizo inikeza amamodeli ahlukahlukene aklanyelwe ukuhlangabezana nezidingo ezahlukene zezokwelapha, kusukela ekuthwebuleni izithombe okunesisombululo esiphezulu kuya ekuthwebuleni okusheshayo, komzimba wonke. Uchungechunge lwe-GE's Revolution CT, uchungechunge lwe-Siemens' SOMATOM, uchungechunge lwe-Philips' Incisive CT, kanye nochungechunge lwe-Canon's Aquilion konke kuyizinketho ezihlonishwayo ezinikeza ubuchwepheshe obusezingeni eliphezulu. Le mishini iyatholakala ukuthi ithengwe ngqo kubakhiqizi noma ngabathengisi bemishini yezokwelapha abagunyaziwe, ngamanani ahlukahluka kakhulu kuye ngemodeli, amakhono okuthwebula izithombe, kanye nesifunda.
Umjovo we-CTs: Umjovo Owodwa we-CTfuthiUmjovo Wekhanda Elibili we-CT
Ama-injector e-CT, okuhlanganisa izinketho ze-single-Head kanye ne-dual-Head, adlala indima ebalulekile ekunikezeni ama-contrast agent ngesikhathi sokuskena kwe-CT. Lawa ma-injector avumela ukulawula okunembile kokujova kwe-contrast media, okuthuthukisa ukucaca kwemithambo yegazi, izitho zomzimba, kanye nezinye izakhiwo ezithombeni eziphumayo. Ama-injector e-Single-Head asetshenziselwa ukuphathwa kwe-contrast okuqondile, kuyilapho ama-injector e-dual-Head angaletha ama-agent noma izixazululo ezimbili ezihlukene ngokulandelana noma ngasikhathi sinye, okuthuthukisa ukuguquguquka kokulethwa kwe-contrast ukuze kutholakale izidingo zesithombe eziyinkimbinkimbi kakhulu.
Ukusebenza kwe-Umjovo we-CTkudinga ukuphathwa ngokucophelela kanye nokusetha. Ngaphambi kokusebenzisa, ochwepheshe kumele bahlole i-injector ukuthola noma yiziphi izimpawu zokungasebenzi kahle futhi baqinisekise ukuthi i-contrast agent ilayishwe kahle ukuze kugwenywe ama-air embolism. Ukugcina insimu ehlanzekile ezungeze indawo yokujova nokulandela izinqubo zokuphepha ezifanele kubalulekile. Ngaphezu kwalokho, kubalulekile ukuqapha isiguli kulo lonke umjovo ukuthola noma yikuphi ukusabela okubi ku-contrast agent. Ama-injector e-Single-Head alula futhi avame ukuthandwa kuma-scan ajwayelekile, kuyilapho ama-injector e-dual-Head efanelekile kakhulu ekuthathweni kwezithombe okuthuthukisiwe, lapho kudingeka khona ukuphathwa kwe-contrast yezigaba eziningi.
Imikhiqizo edumile yama-CT injector ifaka phakathi i-MEDRAD (eyaseBayer), i-Guerbet, kanye ne-Nemoto, enikeza amamodeli e-single kanye ne-dual-Head. I-MEDRAD Stellant injector, isibonelo, isetshenziswa kabanzi futhi yaziwa ngokuthembeka kwayo kanye ne-interface elula ukuyisebenzisa, kuyilapho uchungechunge lwe-Dual Shot lwe-Nemoto lunikeza amakhono athuthukisiwe okujova ama-dual-Head. Lawa ma-injector avame ukuthengiswa ngabasabalalisi abagunyaziwe noma ngokuqondile kubakhiqizi futhi aklanyelwe ukusebenza ngaphandle kokuphazamiseka nemikhiqizo ehlukahlukene ye-CT scanner, ukuqinisekisa ukuhambisana nokusebenza okulungiselelwe izidingo zezithombe zezokwelapha.
Kusukela ngo-2019, i-LnkMed yethule i-Honor C-1101 (Umjovo we-CT onekhanda elilodwa) kanye ne-Honor C-2101 (Umjovo we-CT onekhanda eliphindwe kabili), zombili zinobuchwepheshe obuzenzakalelayo obuklanyelwe ukusekela izinqubo zesiguli ngasinye kanye nezidingo zesithombe ezenzelwe wena.
Lawa ma-injector aklanywe ukuze alulame futhi athuthukise ukusebenza kwe-CT. Anenqubo yokusetha esheshayo yokulayisha izinto zokuhlukanisa nokuxhuma umugqa wesiguli, umsebenzi ongaqedwa ngaphansi kwemizuzu emibili. Uchungechunge lwe-Honor lusebenzisa isirinji engu-200-mL futhi luhlanganisa ubuchwepheshe bokubona uketshezi ngendlela enembile kanye nokunemba komjovo, okwenza kube lula ngabasebenzisi ukufunda ngokuqeqeshwa okuncane.
I-LnkMed'sIzinhlelo zomjovo we-CTinikeza izinzuzo ezahlukahlukene kubasebenzisi, njengokucushwa kwesinyathelo esisodwa kwesivinini sokugeleza, ivolumu, kanye nengcindezi, kanye nekhono lokuskena okuqhubekayo okunejubane eliphindwe kabili ukugcina ukuhlushwa kwe-ejenti yokungafani kuzinzile kuma-CT scan amaningi ajikelezayo. Lokhu kusiza ekwembuleni izici zemithambo yegazi kanye nezilonda ezinemininingwane eminingi. Yakhelwe ukuqina engqondweni, ama-injector anemiklamo engangeni manzi yokuqinisa ukuzinza kanye nengozi encishisiwe yokuvuza. Izilawuli zesikrini sokuthinta kanye nemisebenzi ezenzakalelayo zithuthukisa ukusebenza kahle komsebenzi, okuholela ekugugeni okuncane kwedivayisi ngokuhamba kwesikhathi, okwenza kube utshalomali olungabizi.
Kwabochwepheshe bezempilo, imodeli yomshini wokujova onezinhloko ezimbili ivumela ukujova okuphambene kanye nosawoti ngesikhathi esisodwa ngezilinganiso ezahlukene, okuthuthukisa ukucaca kwezithombe kuwo womabili ama-ventricle. Lesi sici siqinisekisa ukuncishiswa okulinganiselayo phakathi kwama-ventricle angakwesokudla nakwesobunxele, kunciphisa izinto ezidaliwe, futhi kuvumela ukubonakala okucacile kwemithambo yenhliziyo nemithambo yenhliziyo efanele ngokuskena okukodwa, okuthuthukisa ukunemba kokuxilonga.
