ukwethula
Ubuchwepheshe be-X-ray bushintshe kakhulu izithombe zezokwelapha, okwenza ochwepheshe bezokwelapha bakwazi ukuxilonga nokwelapha izifo eziningi ngokunembile. Inhliziyo yalobu buchwepheshe ithubhu le-X-ray, into ebalulekile eye yathuthuka kakhulu eminyakeni edlule. Kulesi sihloko sebhulogi, sizohlola umlando kanye nentuthuko yalokhu.Amashubhu e-X-raykanye nomthelela wazo ekuthathweni kwezithombe zezokwelapha zesimanje.
Kusenesikhathi
Umqondo we-X-ray watholakala nguWilhelm Conrad Röntgen ngo-1895, okwaholela ekusungulweni kwe-X-ray tube yokuqala. Ama-X-ray tube okuqala ayenomklamo olula, owakhiwa i-cathode kanye ne-anode ngaphakathi kwe-vacuum tube. Kwasetshenziswa i-voltage ephezulu, kwasheshisa ama-electron aye ku-anode, lapho ashayisana khona nezinto eziqondiwe, kwakhiqizwa ama-X-ray. Lesi simiso esiyisisekelo sabeka isisekelo sentuthuko yesikhathi esizayo kuma-X-ray tube.
Intuthuko yokuklama
Njengoba isidingo samakhono okuthwebula izithombe athuthukile sikhula, nesidingo samashubhu e-X-ray athuthukisiwe siyakhula. Eminyakeni edlule, ukwakheka nokwakhiwa kwamashubhu e-X-ray kuthuthuke kakhulu. Amashubhu e-X-ray anamuhla afakwe ama-anode ajikelezayo, okwenza kube namandla aphezulu kanye nokushabalaliswa kokushisa, okuholela ezikhathini ezinde zokuvezwa kanye nekhwalithi yesithombe ethuthukisiwe. Ngaphezu kwalokho, ukuthuthukiswa kobuchwepheshe be-X-ray yedijithali kuthuthukise kakhulu ukusebenza kwamashubhu e-X-ray, okuvumela izithombe ezinesinqumo esiphezulu ngenkathi kunciphisa ukuvezwa kwemisebe yesiguli.
Izicelo ekuthathweni kwezithombe zezokwelapha
Ukuvela kwamashubhu e-X-ray kube nomthelela omkhulu ekuthathweni kwezithombe zezokwelapha. Ubuchwepheshe be-X-ray manje busetshenziswa kabanzi ekuxilongeni, okwenza ochwepheshe bezokwelapha bakwazi ukubona ngeso lengqondo izakhiwo zangaphakathi futhi bathole ukukhubazeka. Kusukela ekutholeni ukwaphuka kanye nezimila kuya ekuqondiseni ukuhlinzwa okungangenisi kakhulu, amashubhu e-X-ray adlala indima ebalulekile ekunakekelweni kwezempilo kwanamuhla.
Ukusungula izinto ezintsha esikhathini esizayo
Uma sibheka phambili, ikusasa lamashubhu e-X-ray libukeka likhanya nakakhulu. Ucwaningo oluqhubekayo kanye nentuthuko lugxile ekuthuthukiseni ukusebenza kahle kwamashubhu e-X-ray, okuhloswe ngalo ukuthuthukisa ikhwalithi yesithombe nokunciphisa ukuvezwa kwemisebe. Ngaphezu kwalokho, ukuhlanganiswa kobuhlakani bokwenziwa kanye nama-algorithms okufunda komshini kunamandla okuguqula ukuchazwa kwezithombe ze-X-ray, okwenza kube nokuxilongwa okunembe kakhudlwana kanye nezinhlelo zokwelapha ezenzelwe wena.
Ekuphetheni
Ukuvela kwamashubhu e-X-ray kudlale indima ebalulekile ekuthuthukisweni kwezithombe zezokwelapha. Kusukela ekuqaleni kwazo okuphansi kuya kobuchwepheshe obusezingeni eliphezulu banamuhla,Amashubhu e-X-raykuvule indlela yamakhono okuxilonga athuthukisiwe kanye nokunakekelwa kweziguli. Njengoba ucwaningo kanye nokusungula izinto ezintsha kuqhubeka nokuthuthukisa amashubhu e-X-ray, ikusasa lezithombe zezokwelapha libonakala liqhakazile kunanini ngaphambili.
