Ubuchwepheshe be-X-ray buye benza izinguquko kwezokwelapha zesimanje, baba ithuluzi elibalulekile ekuxilongeni nasekwelapheni izifo ezihlukahlukene. Enhliziyweni yobuchwepheshe be-X-ray kukhonaX-ray tube, umshini okhiqiza imisebe ye-electromagnetic, ebese isetshenziselwe ukwakha izithombe zezakhi zangaphakathi zomzimba womuntu.
An X-ray tubeiqukethe i-cathode, i-anode kanye ne-vacuum tube. I-cathode ikhokhiswa kabi futhi ngokuvamile yenziwe nge-tungsten, kuyilapho i-anode ishajwa kahle futhi ngokuvamile yenziwe ngethusi noma i-tungsten. Lapho i-cathode ishiselwa ezingeni lokushisa eliphezulu, ama-electron akhishwa futhi asheshiswe aye ku-anode, lapho eshayisana khona nento eqondiwe. Lokhu kushayisana kukhiqiza ama-photon e-X-ray ahamba ngeshubhu le-vacuum aye entweni ehlolwayo.
Esinye sezici ezibalulekile zeshubhu le-X-ray yikhono le-anode lokuqeda ukushisa okukhiqizwa ama-electron ashayisana nalokho okuhlosiwe. Ama-anode ngokuvamile anokulungiselelwa kwediski elizungezayo elidizayinelwe ukuqeda ukushisa ngendlela efanele kuyilapho kugcinwa ubuqotho besakhiwo sedivayisi. Njengoba ubuchwepheshe be-anode buthuthuka, amashubhu amasha angakhiqiza izithombe zekhwalithi ephezulu kuyilapho edinga ukulungiswa okuncane nempilo ende.
Esinye isici esibalulekile sobuchwepheshe be-X-ray ukulawula ukuchayeka kwemisebe. Ngenxa yokuthi ukuchayeka emazingeni aphezulu emisebe kungaba nemiphumela elimazayo emzimbeni womuntu, amashubhu e-X-ray esimanje aklanyelwe ukunciphisa ukuchayeka emisebeni. Isibonelo, amanye amashubhu e-X-ray anezilawuli zokuchayeka ezizenzakalelayo ezilungisa ukuchayeka emisebeni ngokusekelwe ezintweni ezifana nosayizi womzimba kanye nohlobo lwethishu. Lokhu kubangela ukuthwebula okunembe kakhudlwana kanye nokuchayeka emisebeni okuncane.
Ekugcineni, yesimanjeX-ray amashubhuinezici ezengeziwe ezihlukile ezithuthukisa ukusebenza nokusebenziseka. Isibonelo, amanye amashubhu anokugxila okulungisekayo, okuvumela abasebenzisi ukuthi bashune kahle usayizi nokuma kwe-X-ray ukuze ivumelane nezidingo zabo ezithile. Amanye amashubhu afakwe isistimu yokupholisa ethuthukisiwe ukuze asetshenziswe isikhathi eside, ukunciphisa isikhathi sokuphumula nokwandisa ukusebenza kahle.
Sengiphetha, ubuchwepheshe beshubhu ye-X-ray sebuhambe ibanga elide kusukela baqala futhi buyaqhubeka nokuvela nanamuhla. Ngokuthuthuka kobuchwepheshe be-anode, izilawuli zokuchayeka emisebeni, namanye amakhono, esimanjemanjeX-ray amashubhukuwumsebenzi ohlaba umxhwele wobunjiniyela osize ochwepheshe bezokwelapha abaningi ukuba bahlole futhi belaphe izifo ezihlukahlukene. Njengoba ubuchwepheshe buqhubeka nokuvela, kuyajabulisa ukucabanga ukuthi iyiphi intuthuko entsha kubuchwepheshe be-X-ray tube esizosivumela ukuthi siyifinyelele esikhathini esizayo.
