Emkhakheni wezithombe zezokwelapha, amashubhu e-X-ray kanye nama-CT scanner kuyizindlela ezimbili zobuchwepheshe ezishintshe indlela yokuxilonga eyenziwa ngayo. Nakuba womabili la madivayisi esebenzisa ama-X-ray ukuze abone izakhiwo zangaphakathi zomzimba womuntu, asebenza ngendlela ehlukile futhi anezindlela ezahlukene zokusebenzisa. Ukuqonda umehluko phakathi kwamashubhu e-X-ray kanye nama-CT scanner kubalulekile kokubili kubasebenzi bezokwelapha kanye neziguli ngoba kuthinta ukukhetha kwabo ubuchwepheshe obufanele bokuthwebula izithombe ngokwezidingo zabo zezokwelapha.
Amashubhu e-X-ray: izinto eziyisisekelo
An Ishubhu le-X-rayiyithuluzi elikhiqiza ama-X-ray ngokusheshisa ama-electron bese liwaqondisa endaweni ethile, ngokuvamile eyenziwe nge-tungsten. Lapho la ma-electron anamandla aphezulu eshayisana ne-target, akhiqiza ama-X-ray angangena emzimbeni bese enza isithombe efilimini noma kumshini wokuthola idijithali. Ukuthwebula izithombe ze-X-ray zendabuko kusetshenziselwa kakhulu ukuhlola amathambo, ukuthola ukwaphuka, kanye nokuxilonga izimo ezifana ne-pneumonia noma izimila zesifuba.
Izinzuzo eziyinhloko zamashubhu e-X-ray ukuthi ashesha futhi asebenza kahle. Ukuhlolwa kwe-X-ray okujwayelekile kuthatha imizuzu embalwa kuphela ukuqeda, okwenza kube kuhle ezimweni eziphuthumayo. Ngaphezu kwalokho, imishini ye-X-ray ngokuvamile itholakala kalula futhi ishibhile kunezikena ze-CT, okwenza kube ithuluzi elivamile, eliphambili lokuthwebula izithombe ezikhungweni eziningi zezokwelapha.
Ama-CT scanner: isinyathelo esengeziwe
Ngakolunye uhlangothi, izikena ze-computed tomography (CT) zithuthukise ubuchwepheshe bokuthwebula izithombe. Izikena ze-CT zisebenzisa ishubhu le-X-ray elijikelezayo ukuze zithwebule izithombe eziningi ezivela emakhoneni ahlukene omzimba. Lezi zithombe zibe sezicutshungulwa yikhompyutha ukuze zenze izingcezu zomzimba eziwela phansi, zinikeze umbono onemininingwane eminingi wezakhiwo zangaphakathi kunezithombe ze-X-ray zendabuko.
Imininingwane ethuthukisiwe enikezwa yi-CT scans iwusizo kakhulu ekuxilongeni izimo eziyinkimbinkimbi, njengokulimala kwangaphakathi, umdlavuza, kanye nezifo ezithinta izicubu ezithambile. I-CT scans ingaveza ulwazi mayelana nezitho zomzimba, imithambo yegazi, ngisho nezimila ezingase zingabonakali kuma-X-ray ajwayelekile. Kodwa-ke, lokhu kwanda kwemininingwane kuza ngentengo; I-CT scans ngokuvamile ihilela ukuchayeka okukhulu emisebeni kune-X-ray esetshenziswayo.
Umehluko omkhulu ekuthwebuleni izithombe
Ikhwalithi yesithombe nemininingwane: Omunye umehluko obaluleke kakhulu phakathi kwamashubhu e-X-ray kanye nezikena ze-CT yizinga lemininingwane ezithombeni ezizikhiqizayo. Ama-X-ray ahlinzeka ngokubuka okunezinhlangothi ezimbili, kuyilapho izikena ze-CT zinikeza izithombe ezinobukhulu obuthathu ezingakhiwa kabusha zibe yizigaba ezahlukene, okuvumela ukuhlolwa okuphelele kwendawo okuqondiwe kuyo.
Ukuchayeka emisebeniNjengoba kushiwo ngaphambili, ama-CT scan avame ukuveza iziguli emazingeni aphezulu emisebeni kune-X-ray ejwayelekile. Lesi sici sibalulekile uma kucatshangelwa izingozi nezinzuzo zendlela ngayinye yokuthwebula izithombe, ikakhulukazi kubantu abasengozini njengezingane noma iziguli ezidinga ama-scan amaningi.
Izinkomba zokusetshenziswaAmashubhu e-X-ray avame ukusetshenziselwa ukuhlola okulula, njengokuhlola amathambo aphukile noma izifo. Ngokuphambene nalokho, ama-CT scanner afaneleka kangcono ezinseleleni zokuxilonga eziyinkimbinkimbi, njengokuhlola ubuhlungu besisu, ukuthola izimila, noma ukuhlela ukungenelela kokuhlinzwa.
Izindleko kanye nokufinyeleleka: Imishini ye-X-ray ngokuvamile ishibhile kakhulu futhi itholakala kabanzi ezindaweni ezahlukene zokunakekelwa kwempilo, okuhlanganisa neminyango yeziguli ezingalaliswa esibhedlela kanye neyosizo oluphuthumayo. Ama-CT scanner, yize enikeza amakhono aphezulu okuthwebula izithombe, abiza kakhulu futhi angase angatholakali kalula kuzo zonke izindawo zokunakekelwa kwempilo.
Ekuphetheni
Ngamafuphi, kokubiliAmashubhu e-X-raykanye nama-CT scanner adlala indima ebalulekile ekuthathweni kwezithombe zezokwelapha, futhi ngalinye linezinzuzo kanye nemikhawulo yalo ehlukile. Ukuqonda umehluko phakathi kwalezi zindlela zobuchwepheshe ezimbili kungasiza abahlinzeki bezempilo ukuthi benze izinqumo ezinolwazi mayelana nokuthi iyiphi indlela yokuthwebula izithombe engcono kakhulu ezigulini zabo. Njengoba ubuchwepheshe buqhubeka buthuthuka, ukuhlanganiswa kwe-X-ray kanye ne-CT imaging cishe kuzoqhubeka nokukhula, kuthuthukise amakhono okuxilonga kanye nokunakekelwa kweziguli.
