Amashubhu e-X-ray ezimboni ayizingxenye ezibalulekile ekuhlolweni okungonakalisi (NDT) kanye nezinqubo zokuhlola, asetshenziswa kabanzi ezimbonini ezifana nezindiza, izimoto, kanye nokukhiqiza. Umsebenzi wawo oyinhloko ukukhiqiza ama-X-ray akwazi ukungena ezintweni, ngaleyo ndlela abone amaphutha angaphakathi, ubuqotho besakhiwo, kanye nokwakheka kwezinto. Kwabochwepheshe kulo mkhakha, ukuqonda ukuthi lezi zintoAmashubhu e-X-rayumsebenzi kanye nomthelela wazo ekunembeni kokuhlola kubalulekile.
Umgomo oyinhloko wamashubhu e-X-ray ezimboni uthiukukhishwa kwe-thermionic, lapho ama-electron ekhishwa khona esuka ku-cathode eshisayo bese esheshiswa aye ku-anode. Lapho la ma-electron anamandla aphezulu eshayisana nezinto ze-anode, kukhiqizwa ama-X-ray. Ikhwalithi kanye nezici ze-X-ray ezikhiqizwayo kuncike ezintweni ezahlukahlukene, okuhlanganisa ukwakheka kweshubhu le-X-ray, izinto ezisetshenziswayo, kanye nezimo zokusebenza.
Esinye sezici ezibalulekile ezithinta ukunemba kokuhlolwa yi-izinga lamandlayemisebe ye-X ekhiqizwayo. Imisebe ye-X enamandla aphezulu ingangena ezintweni ezixineneyo, okwenza zifaneleke ukuhlola izingxenye ezijiyile. Ngokuphambene nalokho, imisebe ye-X enamandla aphansi ifaneleka kangcono ukuhlola amaphutha ebusweni bezinto ezincane. Ngokulungisa ukuphuma kwamandla kweshubhu ye-X-ray, abahloli bangenza indlela yokuhlola ivumelane nezidingo ezithile zomsebenzi, ngaleyo ndlela bathuthukise ukunemba kokuhlola.
Esinye isici esithonyayo yi-usayizi oqondileyeshubhu ye-X-ray. Usayizi omncane we-focal ukhiqiza izithombe ezinesisombululo esiphezulu, okubalulekile ekuboneni amaphutha amancane. Ngokuphambene nalokho, usayizi omkhulu we-focal ungaholela ekulahlekelweni kwemininingwane, okwenza amaphutha angatholakali. Ngakho-ke, ukukhetha ishubhu ye-X-ray enosayizi we-focal ofanele kubalulekile ukuze kutholakale imiphumela emihle kakhulu yokuthola.
I-geometry yeshubhu le-X-ray nayo idlala indima ebalulekile ekuqondeni kokuhlola. I-engeli yokukhishwa kwe-X-ray ithinta ikhwalithi yesithombe. Isibonelo, ishubhu le-X-ray eliyi-angle elungisekayo lingamboza kangcono amajiyomethri ayinkimbinkimbi, liqinisekise ukuhlolwa okuphelele kwazo zonke izindawo zengxenye. Lokhu kuguquguquka kubaluleke kakhulu ezimbonini ezinemiklamo yezingxenye eziyinkimbinkimbi noma isikhala sokusebenza esilinganiselwe.
Ngaphezu kwalokho, ukuzinza kanye nokuvumelana kokukhishwa kwe-X-ray kubalulekile ekuhlolweni okuthembekile. Ukuguquguquka kokuqina kwe-X-ray kungaholela ekushintsheni kwekhwalithi yesithombe, ngaleyo ndlela kuthinte ikhono lokubona amaphutha. Amashubhu e-X-ray ezimboni zanamuhla aklanywe ngobuchwepheshe obuthuthukisiwe ukuqinisekisa ukuphuma okuzinzile, ngaleyo ndlela kuthuthukiswe ukuphindaphindeka kanye nokuthembeka kwemiphumela yokuhlola.
Ngaphandle kwezici zobuchwepheshe ze-X-ray tube, ukuhlanganiswa kwezinhlelo zezithombe zedijithali kuthuthukisa kakhulu ukunemba kokuhlola. Ama-digital detector athwebula izithombe ezinesinqumo esiphezulu futhi anikeze impendulo yesikhathi sangempela, okwenza abahloli bakwazi ukwenza ukuhlolwa okusheshayo. Lokhu kuhlanganiswa akusheshisi nje kuphela ukuhlolwa kodwa futhi kuthuthukisa kakhulu ukunemba kokuhlonza nokuhlaziya amaphutha.
Ngamafuphi, amashubhu e-X-ray ezimboni ayizici ezibalulekile zokufeza ukunemba okuphezulu ekuhlolweni okungonakalisi. Izimiso zawo zokusebenza, okuhlanganisa amazinga wamandla, usayizi wendawo egxile, i-geometry, kanye nokuqina kokukhipha, kuthinta ngqo ikhwalithi yemiphumela yokuhlolwa. Ngokuthuthuka okuqhubekayo kwezobuchwepheshe, ukusebenza kweAmashubhu e-X-ray bazoqhubeka nokuthuthuka, bathuthukise indima yabo ekuqinisekiseni ukuphepha nokuthembeka kwezingxenye ezibalulekile kuzo zonke izimboni ezahlukene. Ukuqonda lezi zici kubalulekile kochwepheshe abafisa ukwenza ngcono izinqubo zabo zokuhlola nokugcina amazinga okulawula asezingeni eliphezulu.
