Emkhakheni wezithombe zezokwelapha, amashubhu e-X-ray kanye nezikena ze-CT ziwubuchwepheshe obubili obuyinhloko obuguqule indlela yokuxilongwa okwenziwa ngayo. Nakuba zombili lezi zisetshenziswa zisebenzisa ama-X-ray ukuze zibuke izakhi zangaphakathi zomzimba womuntu, zisebenza ngendlela ehlukile futhi zinokusetshenziswa okuhlukile. Ukuqonda umehluko phakathi kwamashubhu e-X-ray nezithwebuli ze-CT kubalulekile kubo bobabili abasebenzi bezokwelapha neziguli ngoba kuthinta ukukhetha kwabo ubuchwepheshe obufanele bokuthwebula ngezithombe ngezidingo zabo zomtholampilo.
Amashubhu e-X-Ray: Okuyisisekelo
An X-ray tubeiwumshini okhiqiza ama-X-ray ngokusheshisa ama-electron futhi uwaqondise entweni okuhlosiwe, ngokuvamile eyenziwe nge-tungsten. Lapho la ma-electron anamandla amakhulu eshayisana nalokho okuhlosiwe, akhiqiza ama-X-ray akwazi ukungena emzimbeni futhi akhe isithombe efilimini noma emtshineni wedijithali. Ukuthwebula kwe-X-ray kwendabuko kusetshenziswa ngokuyinhloko ukuhlola amathambo, ukubona ukuphuka, nokuxilonga izimo ezifana nenyumoniya noma izimila zesifuba.
Izinzuzo eziyinhloko zamashubhu e-X-ray yijubane nokusebenza kwawo. Ukuhlolwa kwe-X-ray okujwayelekile kuthatha imizuzu embalwa kuphela ukuqeda, okuyenza ilungele izimo eziphuthumayo. Ukwengeza, imishini ye-X-ray ngokuvamile itholakala kalula futhi ingabizi kakhulu kunemishini yokuthwebula i-CT, okuyenza ibe ithuluzi elivamile lokuthwebula izithombe ezikhungweni eziningi zezokwelapha.
Izikena ze-CT: isinyathelo esiqhubekayo
Izikena ze-Computed tomography (CT), ngakolunye uhlangothi, zithathe ubuchwepheshe bokuthwebula zazisa ezingeni elisha. Izikena ze-CT zisebenzisa ishubhu ye-X-ray ezungezayo ukuze zithwebule izithombe eziningi kuma-engeli ahlukene omzimba. Lezi zithombe zibe sezicutshungulwa ikhompuyutha ukuze zenze izingcezu zomzimba ezihlukene, zinikeze umbono onemininingwane eminingi yezakhiwo zangaphakathi kunomfanekiso we-X-ray ovamile.
Imininingwane ethuthukisiwe ehlinzekwa ama-CT scans inenzuzo ikakhulukazi ekuxilongeni izimo eziyinkimbinkimbi, njengokulimala kwangaphakathi, umdlavuza, nezifo ezithinta izicubu ezithambile. Ama-CT scan angaveza ulwazi mayelana nezitho, imithambo yegazi, ngisho nezimila okungenzeka zingabonakali kuma-X ray avamile. Nokho, lokhu kwanda ngemininingwane kuza ngentengo; Ama-CT scan ngokuvamile ahilela ukuchayeka emisebeni ephezulu kune-X-ray yendabuko.
Umehluko omkhulu ezithombeni
Ikhwalithi yesithombe nemininingwane: Omunye umehluko obaluleke kakhulu phakathi kwamashubhu e-X-ray nezithwebuli ze-CT izinga lemininingwane ezithombeni ezizikhiqizayo. Ama-X-ray ahlinzeka ngombono onezinhlangothi ezimbili, kuyilapho ama-CT scan ahlinzeka ngezithombe ezinezinhlangothi ezintathu ezingakhiwa kabusha zibe izindiza ezihlukene, okuvumela ukuhlolwa okubanzi kwendawo okuhlosiwe.
Ukuchayeka ngemisebe: Njengoba kushiwo ngaphambili, ama-CT scan ngokuvamile achaya iziguli emazingeni aphezulu emisebe kune-X-ray evamile. Lesi sici sibalulekile uma kucatshangelwa ubungozi nezinzuzo zendlela ngayinye yokuthwebula, ikakhulukazi kubantu abasengozini njengezingane noma iziguli ezidinga ukuskenwa okuningi.
Izinkomba zokusetshenziswa: Amashubhu e-X-ray ngokuvamile asetshenziselwa ukuhlola okulula, njengokuhlola amathambo aphukile noma izifo. Ngokuphambene, izikena ze-CT zifaneleka kangcono izinselele zokuxilonga eziyinkimbinkimbi, njengokuhlola ubuhlungu besisu, ukuthola izimila, noma ukuhlela ukungenelela kokuhlinzwa.
Izindleko nokufinyeleleka: Imishini ye-X-ray ngokuvamile ibiza kakhulu futhi itholakala kabanzi ezindaweni ezihlukahlukene zokunakekelwa kwezempilo, okuhlanganisa iziguli ezilaliswa ngaphandle kanye neminyango yezimo eziphuthumayo. Izikena ze-CT, ngenkathi zinikeza amakhono aphakeme wokuthwebula izithombe, zibiza kakhulu futhi zingase zingatholakali kalula kuzo zonke izilungiselelo zokunakekelwa kwezempilo.
Ekuphetheni
Kafushane, kokubiliX-ray amashubhukanye nezithwebuli ze-CT zidlala indima ebalulekile ekucabangeni kwezokwelapha, futhi ngayinye inezinzuzo zayo eziyingqayizivele nokulinganiselwa kwayo. Ukuqonda umehluko phakathi kwalobu buchwepheshe obubili kungasiza abahlinzeki bezokunakekelwa kwempilo benze izinqumo ezinolwazi mayelana nendlela yokucabanga engcono kakhulu ezigulini zabo. Njengoba ubuchwepheshe buqhubeka buthuthuka, ukuhlanganiswa kwe-X-ray kanye ne-CT imaging cishe kuzoqhubeka nokuvela, kuthuthukise amakhono okuxilonga nokunakekelwa kwesiguli.
