Iiskena zeComputed Tomography (CT) zizixhobo eziphambili zokujonga imifanekiso ezibonelela ngemifanekiso eneenkcukacha ezinqamlezileyo yezakhiwo zangaphakathi zomzimba. Zisebenzisa ii-X-ray kunye netekhnoloji yekhompyutha, ezi matshini zenza imifanekiso eneengqimba okanye "iziqwenga" ezinokudityaniswa zibe yimbonakalo ye-3D. Inkqubo ye-CT isebenza ngokuqondisa imisebe ye-X-ray emzimbeni ukusuka kwii-engile ezahlukeneyo. Ezi misebe emva koko zifunyanwa ziisensa ezikwelinye icala, kwaye idatha icutshungulwa yikhompyutha ukuvelisa imifanekiso ephezulu yamathambo, izicubu ezithambileyo, kunye nemithambo yegazi. I-CT imaging ibalulekile ekuxilongeni uluhlu olubanzi lweemeko zonyango, ukusuka ekwenzakaleni ukuya kumhlaza, ngenxa yokukwazi kwayo ukubonelela ngemifanekiso ecacileyo neneenkcukacha ye-anatomy yangaphakathi.
Ii-CT scanners zisebenza ngokulalisa isigulana etafileni enenjini esiya kwisixhobo esikhulu esijikelezayo. Njengoko ityhubhu ye-X-ray ijikeleza isigulana, ii-detectors zibamba ii-X-rays ezidlula emzimbeni, ezithi emva koko ziguqulwe zibe yimifanekiso yi-algorithms yekhompyutha. Olu tyando lukhawuleza kwaye alunabungozi, uninzi lwee-scans lugqitywa kwimizuzu embalwa. Uphuhliso oluphambili kwitekhnoloji ye-CT, njengesantya esikhawulezayo sokujonga imifanekiso kunye nokunciphisa ukuvezwa kwemitha, kuyaqhubeka nokuphucula ukhuseleko lwesigulana kunye nokusebenza kakuhle kokuxilongwa. Ngoncedo lwee-CT scanners zanamhlanje, oogqirha banokwenza i-angiography, i-colonoscopy ebonakalayo, kunye ne-cardiac imaging, phakathi kwezinye iinkqubo.
Iimpawu eziphambili kwimarike ye-CT scanner ziquka i-GE Healthcare, i-Siemens Healthineers, i-Philips Healthcare, kunye ne-Canon Medical Systems. Ngayinye kwezi mpawu inikezela ngeemodeli ezahlukeneyo ezenzelwe ukuhlangabezana neemfuno ezahlukeneyo zeklinikhi, ukusuka kwimifanekiso enesisombululo esiphezulu ukuya kwi-scan ekhawulezayo, yomzimba wonke. Uthotho lwe-GE's Revolution CT, uthotho lwe-Siemens' SOMATOM, uthotho lwe-Philips' Incisive CT, kunye nothotho lwe-Canon's Aquilion zonke ziinketho ezihlonitshwayo ezibonelela ngobuchwepheshe obuphezulu. Ezi matshini ziyafumaneka ukuze zithengwe ngokuthe ngqo kubavelisi okanye ngabathengisi bezixhobo zonyango abagunyazisiweyo, kunye namaxabiso ahluka kakhulu kuxhomekeke kwimodeli, amandla okuthatha imifanekiso, kunye nommandla.
I-CT Injectors: I-CT Single InjectorkwayeI-CT Dual Head Injector
Ii-injectors ze-CT, kuquka ukhetho lwe-single-Head kunye ne-dual-Head, zidlala indima ebalulekileyo ekulawuleni ii-contrast agents ngexesha le-CT scans. Ezi injectors zivumela ulawulo oluchanekileyo kwi-injection ye-contrast media, nto leyo ephucula ukucaca kwemithambo yegazi, amalungu omzimba, kunye nezinye izakhiwo kwimifanekiso ephumayo. Ii-injectors ze-Single-Head zisetyenziselwa ulawulo oluthe ngqo lwe-contrast, ngelixa ii-injectors ze-dual-Head zinokuhambisa ii-agents okanye izisombululo ezimbini ezahlukeneyo ngokulandelelana okanye ngaxeshanye, ziphucula ukuguquguquka kokuhanjiswa kwe-contrast kwiimfuno zemifanekiso ezinzima ngakumbi.
Ukusebenza kweI-CT injectorifuna ukuphathwa kakuhle kunye nokuseta. Ngaphambi kokusetyenziswa, iingcali kufuneka zijonge i-injector ukuba azikho na iimpawu zokungasebenzi kakuhle kwaye ziqinisekise ukuba i-contrast agent ilayishwe ngokuchanekileyo ukuze kuthintelwe i-air embolisms. Ukugcina indawo engenazintsholongwane ejikeleze indawo yenaliti kunye nokulandela imigaqo efanelekileyo yokhuseleko kubalulekile. Ukongeza, kubalulekile ukujonga isigulana kulo lonke inaliti ukuze kujongwe naziphi na iziphumo ezibi kwi-contrast agent. Ii-injector ze-Single-Head zilula kwaye zihlala zikhethwa kwiiskeni eziqhelekileyo, ngelixa ii-injector ze-dual-Head zilungele ngakumbi imifanekiso ephucukileyo, apho kufuneka ulawulo lwe-contrast lwamanqanaba amaninzi.
Iimpawu ezidumileyo zee-CT injectors ziquka i-MEDRAD (eyayi-Bayer), i-Guerbet, kunye ne-Nemoto, ezibonelela ngeemodeli ze-single kunye ne-dual-Head. Umzekelo, i-MEDRAD Stellant injector isetyenziswa kakhulu kwaye yaziwa ngokuthembeka kwayo kunye nojongano olulula ukuyisebenzisa, ngelixa uthotho lwe-Dual Shot lwe-Nemoto lubonelela ngezakhono eziphambili zokujova ii-dual-Head. Ezi injectors zihlala zithengiswa ngabasasazi abagunyazisiweyo okanye ngokuthe ngqo kubavelisi kwaye zenzelwe ukusebenza ngokungenamthungo neempawu ezahlukeneyo ze-CT scanner, ukuqinisekisa ukuhambelana kunye nokusebenza okuphuculweyo kwiimfuno zemifanekiso yezonyango.
Ukususela ngo-2019, i-LnkMed iye yazisa i-Honor C-1101 (I-Injector ye-CT yeNtloko enyekunye neHonor C-2101 (I-Double Head CT Injector), zombini zibonisa ubuchwepheshe obuzenzekelayo obuyilelwe ukuxhasa iinkqubo zesigulana ngasinye kunye neemfuno zomfanekiso ezenzelwe wena.
Ezi injectors zenzelwe ukuphucula nokuphucula ukusebenza kwe-CT. Zinenkqubo yokuseta ngokukhawuleza yokulayisha izinto ezichaseneyo kunye nokudibanisa umgca wesigulana, umsebenzi onokugqitywa ngaphantsi kwemizuzu emibini. Olu luhlu lwe-Honor lusebenzisa isirinji ye-200-mL kwaye lubandakanya itekhnoloji yokubonisa ulwelo ngokuchanekileyo kunye nokuchaneka kwenaliti, okwenza kube lula kubasebenzisi ukufunda ngoqeqesho oluncinci.
I-LnkMed'sIinkqubo zokujova nge-CTIbonelela ngeenzuzo ezahlukeneyo kubasebenzisi, ezinje ngoqwalaselo lwenyathelo elinye lomlinganiselo wokuhamba, umthamo, kunye noxinzelelo, kunye nokukwazi ukuskena okuqhubekekayo kwesantya esiphindwe kabini ukugcina uxinaniso lwe-agent yomahluko luzinzile kwi-multi-slice spiral CT scans. Oku kunceda ukutyhila iimpawu ezineenkcukacha ngakumbi zemithambo yegazi kunye nezilonda. Zakhelwe ukuqina engqondweni, ii-injectors zinezakhiwo ezingangeni manzi zokomeleza uzinzo olongezelelekileyo kunye nokunciphisa umngcipheko wokuvuza. Ulawulo lwesikrini sokuchukumisa kunye nemisebenzi ezenzekelayo yonyusa ukusebenza kakuhle komsebenzi, okukhokelela ekugugulekeni kancinci kwezixhobo ngokuhamba kwexesha, okwenza kube lutyalo-mali olunoqoqosho.
Kwabo basebenza ngezempilo, imodeli ye-dual-head injector ivumela ukufakelwa kwe-contrast ngaxeshanye kunye ne-saline injections ngaxeshanye kwii-ratios ezahlukeneyo, iphucula ukucaca komfanekiso kuzo zombini ii-ventricles. Olu phawu luqinisekisa ukuncitshiswa okulinganayo phakathi kwee-ventricles zasekunene nezasekhohlo, lunciphisa izinto ezisetyenzisiweyo, kwaye luvumela ukubonakala ngokucacileyo kwemithambo ye-coronary kunye nee-ventricles zasekunene kwi-scan enye, nto leyo ephucula ukuchaneka kokuxilongwa.
