Izikena ze-Computed Tomography (CT) zingamathuluzi athuthukile wokuxilonga ahlinzeka ngezithombe ezinemininingwane ehlukene yezakhiwo zangaphakathi zomzimba. Isebenzisa ama-X-ray nobuchwepheshe bekhompyutha, le mishini yenza izithombe ezinezingqimba noma “izingcezu” ezingahlanganiswa zibe ukumelwa kwe-3D. Inqubo ye-CT isebenza ngokuqondisa imishayo ye-X-ray emzimbeni isuka kuma-engeli amaningi. Le mishayo ibe isitholwa izinzwa ngakolunye uhlangothi, bese idatha icutshungulwa yikhompyutha ukuze ikhiqize izithombe ezibonisa ukucaca okuphezulu kwamathambo, izicubu ezithambile, nemithambo yegazi. I-CT imaging ibalulekile ekuxilongeni izimo eziningi zezokwelapha, kusukela ekulimaleni kuya kumdlavuza, ngenxa yekhono layo lokuhlinzeka ngemibono ecacile, enemininingwane ye-anatomy yangaphakathi.
Ama-CT scanners asebenza ngokulalisa isiguli etafuleni elinenjini elingena emshinini omkhulu oyindilinga. Njengoba ishubhu le-X ray lizungeza isiguli, imitshina ithwebula ama-X ray adlula emzimbeni, abese eguqulwa abe izithombe ngohlelo lwekhompyutha. Umsebenzi uyashesha futhi awuhlaseli, futhi ukuskena okuningi kuqedwa emizuzwini embalwa. Ukuthuthuka okubalulekile kubuchwepheshe be-CT, njengesivinini sokuthwebula izithombe kanye nokuncipha kokuchayeka emisebeni, kuyaqhubeka nokuthuthukisa ukuphepha kwesiguli nokusebenza kahle kokuxilonga. Ngosizo lwezikena ze-CT zesimanje, odokotela bangenza i-angiography, i-colonoscopy ebonakalayo, ne-cardiac imaging, phakathi kwezinye izinqubo.
Imikhiqizo ehamba phambili emakethe yesithwebuli se-CT ihlanganisa i-GE Healthcare, Siemens Healthineers, Philips Healthcare, kanye neCanon Medical Systems. Ngayinye yale mikhiqizo inikeza amamodeli ahlukahlukene aklanyelwe ukuhlangabezana nezidingo ezahlukene zomtholampilo, kusukela ekufanekisweni okunokulungiswa okuphezulu kuya ekuskeneni okusheshayo, komzimba wonke. Uchungechunge lwe-GE's Revolution CT, uchungechunge lwe-Siemens' SOMATOM, i-Philips' Incisive CT, kanye nochungechunge lwe-Canon's Aquilion zonke izinketho ezibhekwa kahle ezinikeza ubuchwepheshe besimanje. Le mishini iyatholakala ukuze ithengwe ngokuqondile kubakhiqizi noma kubathengisi bemishini yezokwelapha abagunyaziwe, ngezintengo ezihluka kakhulu kuye ngemodeli, amandla esithombe, nendawo.
I-CT Injectors: I-CT Injector EyodwafuthiI-CT Dual Head Injector
Izijovo ze-CT, okuhlanganisa izinketho ze-single-Head kanye ne-dual-Head, zidlala indima ebalulekile ekulawuleni ama-ejenti wokuqhathanisa ngesikhathi sokuskena kwe-CT. Lawa ma-injection avumela ukulawula okunembile kumjovo wemidiya yokuqhathanisa, okuthuthukisa ukucaca kwemithambo yegazi, izitho, nezinye izakhiwo ezithombeni eziwumphumela. Ama-injection ekhanda elilodwa asetshenziselwa ukulawula okuqondile okuhlukile, kuyilapho ama-dual-Head injectors akwazi ukuletha ngokulandelana noma ngesikhathi esisodwa ama-ejenti amabili ahlukene noma izixazululo, athuthukise ukuguquguquka kokulethwa kokugqamayo ngezidingo zesithombe eziyinkimbinkimbi.
Ukusebenza kwe-aCT injectoridinga ukuphathwa nokusethwa ngokucophelela. Ngaphambi kokusetshenziswa, ochwepheshe kufanele bahlole i-injector noma yiziphi izimpawu zokungasebenzi kahle futhi baqinisekise ukuthi i-ejenti yokuqhathanisa ilayishwe ngendlela efanele ukuze kugwenywe i-air embolism. Ukugcina inkambu engenalutho endaweni yomjovo nokulandela izimiso zokuphepha ezifanele kubalulekile. Ukwengeza, kubalulekile ukuqapha isiguli kuwo wonke umjovo nganoma yikuphi ukusabela okungekuhle kumsebenzeli wokuqhathanisa. Ama-injection e-Single Head alula futhi avame ukuncamela ukuskena okujwayelekile, kuyilapho ama-dual-Head ama-injection afaneleka kakhulu ekufanekisweni okuthuthukisiwe, lapho ukulawulwa kokungafani kwezigaba eziningi kuyadingeka.
Izinhlobo ezidumile zamajoyi e-CT zifaka i-MEDRAD (nge-Bayer), i-Guerbet, ne-Nemoto, ehlinzeka ngamamodeli angawodwa kanye nama-dual-Head. Umjovo we-MEDRAD Stellant, ngokwesibonelo, usetshenziswa kabanzi futhi waziwa ngokuthembeka kwawo kanye nesixhumi esibonakalayo esisebenziseka kalula, kuyilapho uchungechunge lwe-Nemoto's Dual Shot lunikeza amakhono athuthukile omjovo wekhanda elikabili. Lawa ma-injection ngokuvamile athengiswa ngabasabalalisi abagunyaziwe noma ngokuqondile kubakhiqizi futhi aklanyelwe ukusebenza ngaphandle komthungo namabhrendi ahlukahlukene wesithwebuli se-CT, ukuqinisekisa ukuhambisana nokusebenza okuthuthukisiwe kwezidingo zesithombe sezokwelapha.
Kusukela ngo-2019, i-LnkMed yethule i-Honor C-1101 (I-Single Head CT Injector) kanye ne-Honor C-2101 (I-Double Head CT Injector), kokubili okunobuchwepheshe obuzenzakalelayo obudizayinelwe ukusekela amaphrothokholi esiguli ngasinye kanye nezidingo zesithombe ezenzelwe wena.
Lawa ma-injection aklanyelwe ukwenza lula futhi athuthukise ukuhamba komsebenzi we-CT. Bafaka inqubo yokusetha esheshayo yokulayisha impahla yokuqhathanisa nokuxhuma ulayini wesiguli, umsebenzi ongaqedwa ngaphansi kwemizuzu emibili. Uchungechunge lwe-Honor lusebenzisa isirinji engu-200-mL futhi luhlanganisa ubuchwepheshe bokubona kahle uketshezi nokunemba komjovo, okwenza kube lula kubasebenzisi ukuthi bafunde ngokuqeqeshwa okuncane.
I-LnkMed'sAmasistimu womjovo we-CTinikeza uhla lwezinzuzo zabasebenzisi, njengokucushwa kwesinyathelo esisodwa sezinga lokugeleza, ivolumu, nokucindezela, kanye nekhono lokuskena okunesivinini esikabili esiqhubekayo ukuze kugcinwe ukugxiliswa kwe-ejenti yokuqhathanisa kuzinzile kumaskena we-CT e-spiral amaningi. Lokhu kusiza ukuveza izici eziningi ze-arterial kanye nezilonda. Yakhelwe ngokuqina engqondweni, ama-injection afaka amadizayini angangeni manzi ukuze kube nokuzinza okwengeziwe kanye nengozi encishisiwe yokuvuza. Izilawuli zesikrini esithintwayo nemisebenzi ezenzakalelayo ithuthukisa ukusebenza kahle komsebenzi, okuholela ekugugeni kwedivayisi ngokuhamba kwesikhathi, okuyenza ibe ukutshalwa kwezimali okongayo.
Kochwepheshe bezokunakekelwa kwempilo, imodeli yomjovo enamakhanda amabili ivumela ukugqama ngasikhathi sinye kanye nemijovo ye-saline ngezilinganiso ezihlukene, ithuthukisa ukucaca kwesithombe kuwo womabili ama-ventricles. Lesi sici siqinisekisa ukulinganisela phakathi kwama-ventricles angakwesokudla nakwesokunxele, kunciphisa ama-artifact, futhi sivumela ukubonakala okucacile kwemithambo yenhliziyo elungile nama-ventricles kusikena esisodwa, okuthuthukisa ukunemba kokuxilonga.
