ethula
Ubuchwepheshe be-X ray buye benza izinguquko ekucabangeni kwezokwelapha, okwenza ochwepheshe bezokwelapha bakwazi ukuxilonga ngokunembile futhi belaphe izimo ezihlukahlukene. Enhliziyweni yalobu buchwepheshe kukhona ishubhu ye-X-ray, ingxenye ebalulekile eye yaba nentuthuko enkulu phakathi neminyaka edlule. Kule bhulogi, sizohlola umlando kanye nentuthukoX-ray amashubhukanye nomthelela wazo emifanekisweni yesimanje yezokwelapha.
Ngaphambili
Umqondo wamaX-ray watholwa nguWilhelm Conrad Röntgen ngo-1895, okwaholela ekusungulweni kweshubhu lokuqala le-X-ray. Amashubhu e-X-ray asekuqaleni ayenomklamo olula, ohlanganisa i-cathode kanye ne-anode ngaphakathi kweshubhu ye-vacuum. Kwasetshenziswa amandla kagesi aphezulu, asheshisa ama-electron aye ku-anode, lapho ashayisana khona nezinto ezihlosiwe, akhiqiza ama-X ray. Lesi simiso esiyisisekelo sabeka isisekelo sentuthuko yesikhathi esizayo kumashubhu e-X-ray.
Ukuthuthuka kwedizayini
Njengoba isidingo samakhono ezithombe athuthuke kakhulu sikhula, sikhula nesidingo samashubhu e-X-ray athuthukisiwe. Ngokuhamba kweminyaka, ukwakhiwa kweshubhu ye-X-ray nokwakhiwa kuthuthuke kakhulu. Amashubhu e-X-ray esimanje afakwe ama-anode ajikelezayo, anika amandla amandla aphezulu kanye nokunqanyulwa kokushisa, okuholela ezikhathini zokuchayeka ezinde kanye nekhwalithi yesithombe ethuthukisiwe. Ngaphezu kwalokho, ukuthuthukiswa kobuchwepheshe be-X-ray yedijithali kuye kwathuthukisa ukusebenza kweshubhu le-X-ray, okwenza izithombe ezinokulungiswa okuphezulu ngenkathi kunciphisa ukuchayeka emisebeni yesiguli.
Izicelo emfanekisweni wezokwelapha
Ukuvela kwamashubhu e-X-ray kube nomthelela omkhulu ezithombeni zezokwelapha. Ubuchwepheshe be-X-ray manje sebusetshenziswa kabanzi ekuxilongeni, okwenza ochwepheshe bezokwelapha bakwazi ukubona ngeso lengqondo izakhiwo zangaphakathi futhi bahlonze okungavamile. Kusukela ekutholeni ukuphuka namathumba kuya ekuhlinzeni okungatheni, amashubhu e-X-ray adlala indima ebalulekile ekunakekelweni kwezempilo kwanamuhla.
Ukuqamba okusha
Uma ubheka phambili, ikusasa lamashubhu e-X-ray libukeka likhanya nakakhulu. Ucwaningo oluqhubekayo nokuthuthukiswa kugxile ekwenzeni ngcono ukusebenza nokusebenza kahle kwamashubhu e-X-ray, okuhloswe ngawo ukuthuthukisa ikhwalithi yesithombe nokunciphisa ukuchayeka emisebeni. Ngaphezu kwalokho, ukuhlanganiswa kobuhlakani bokwenziwa kanye nama-algorithms okufunda komshini kunamandla okuguqula ukuchazwa kwezithombe ze-X-ray, okuvumela ukuxilonga okunembe kakhudlwana kanye nezinhlelo zokwelashwa eziqondene nawe.
Ekuphetheni
Ukuvela kwamashubhu e-X-ray kubambe iqhaza elibalulekile ekuthuthukisweni kwezithombe zezokwelapha. Kusukela ekuqaleni kwabo okuphansi kuya kubuchwepheshe banamuhla obuphambili,X-ray amashubhubaye bavula indlela yamakhono athuthukisiwe okuxilonga nokunakekelwa kwesiguli. Njengoba ucwaningo nokuqamba okusha kuqhubeka nokuqhubekisela phambili amashubhu e-X-ray, ikusasa lezithombe zezokwelapha libukeka liqhakazile kunangaphambili.
