Imishini ye-X-rayzidlala indima ebalulekile kwezokwelapha zanamuhla, zisiza ekuxilongeni nasekwelapha izifo ezahlukahlukene. Enhliziyweni yale mishini kukhona ingxenye ebalulekile ebizwa ngokuthi i-X-ray tube, ekhiqiza ama-X-ray adingekayo ukuze kuthathwe izithombe ezinemininingwane yomzimba womuntu. Ubuchwepheshe be-X-ray tube buthuthuke kakhulu eminyakeni yamuva nje, ikakhulukazi ekuskeni kwe-computed tomography (CT). Le bhulogi ihlose ukuhlola lezi ntuthuko kanye nomthelela wazo ensimini.
Funda ngamapayipi e-X-ray:
An Ishubhu le-X-rayempeleni iyithuluzi elivalwe nge-vacuum eliguqula amandla kagesi abe imisebe ye-X-ray. Intuthuko enkulu kubuchwepheshe be-X-ray tube kwaba ukwethulwa kwama-anode ajikelezayo. Lokhu kusungulwa kwenza amandla aphezulu aphume futhi kube nezikhathi zokuskena ezisheshayo, okwenza ama-CT scan asebenze kahle futhi anembile. Ngaphezu kwalokho, ama-tungsten anamuhla asebenzisa i-tungsten njengezinto eziqondiwe ngenxa yenani layo eliphezulu le-athomu, okwenza kube nokwenzeka ukukhiqizwa kwezithombe ze-X-ray ezisezingeni eliphezulu.
Ukuskena kwe-CT nokuthi kungani kubalulekile:
I-CT scan iyindlela yokuthwebula izithombe yezokwelapha engangenisi umthelela enikeza izithombe zomzimba ezinemininingwane ezihlukanisayo. Lezi zithombe zembula izakhiwo zangaphakathi eziyinkimbinkimbi, ezisiza odokotela ukuthi baxilonge futhi baphathe izimo zezokwelapha ngokunembile. I-CT scan ivame ukusetshenziswa ukuhlola izindawo ezifana nobuchopho, isifuba, isisu kanye ne-pelvis. Intuthuko kwezobuchwepheshe be-X-ray tube ithuthukise kakhulu ukusebenza kahle kanye nokuphepha kwe-CT scans.
Ukulungiswa kwesithombe okuthuthukisiwe:
Intuthuko enkulu kwaba ukuthuthukiswa kwamashubhu e-X-ray anamaphuzu amancane okugxila. Ukugxila kuyisici esibalulekile ekunqumeni ukucaca kwesithombe esiphumayo. Ukugxila okuncane kuthuthukisa ukucaca kwesithombe, okuvumela ukuxilongwa okunembe kakhudlwana. Lokhu kuthuthukiswa kuzuzisa kakhulu ekutholeni ukukhubazeka okuncane kanye nezilonda okungenzeka ukuthi azizange zibonwe yizizukulwane zangaphambilini zamashubhu e-X-ray.
Nciphisa umthamo wemisebe:
Enye inkinga ebalulekile ekuthathweni kwezithombe zezokwelapha ukuchayeka emisebeni. Ukuze kuxazululwe le nkinga, abakhiqizi basebenzise ubuchwepheshe obuklanyelwe ukunciphisa umthamo wemisebe ngesikhathi sokuskena kwe-CT. Ukumelana nokushisa okwandisiwe kwe-X-ray tube, kuhlanganiswe nezindlela zokupholisa ezithuthukisiwe, kwenza kube lula ukwenza izinqubo zokuskena ezinde ngaphandle kokubeka engcupheni ukuphepha kwesiguli. Ngokwenza ngcono ukusebenza kahle kokukhiqizwa kwe-X-ray, lezi ntuthuko zinciphisa ngempumelelo umthamo wemisebe ngenkathi zigcina ikhwalithi yesithombe.
Isivinini kanye nokusebenza okuthuthukisiwe:
Njengoba ubuchwepheshe buthuthuka, nesidingo sokuskena esisheshayo nesisebenza kahle kakhulu siyakhula. Abakhiqizi basabela kulesi sidingo ngokwethula amashubhu e-X-ray akwazi ukukhiqiza imisinga yamashubhu ephezulu, ngaleyo ndlela bandise isivinini sokuskena. Lokhu kuthuthuka kubalulekile ezimweni eziphuthumayo lapho isikhathi sibaluleke kakhulu, okuvumela ochwepheshe bezempilo ukuthi bahlole ngokushesha ukulimala noma izimo ezimbi kakhulu.
Ekuphetheni:
Intuthuko kuIshubhu le-X-rayubuchwepheshe bushintshe kakhulu insimu yokuskena kwe-CT, buhlinzeka ochwepheshe bezempilo ngesisombululo esiphezulu sezithombe, imithamo yemisebe ephansi kanye nesivinini esiphezulu. Lezi ntuthuko zithuthukise kakhulu ukunemba nokusebenza kahle kokuxilongwa nokwelashwa kwezimo zezokwelapha. Njengoba ubuchwepheshe buqhubeka nokukhula, singalindela ukusungulwa okusha okwengeziwe kubuchwepheshe be-X-ray tube, okuvula umnyango wamasu okuthwebula izithombe zezokwelapha anembile futhi angangenisi kakhulu. Ngesinyathelo ngasinye esiya phambili, ikusasa le-radiology liyakhanya, okuholela ekusaseni elinempilo kubo bonke.
