Ubuchwepheshe be-X-ray bushintshe kakhulu ezokwelapha zesimanje, baba ithuluzi elibalulekile lokuxilonga nokwelapha izifo eziningi ezahlukene. Enhliziyweni yobuchwepheshe be-X-ray kukhonaIshubhu le-X-ray, ithuluzi elikhiqiza imisebe kagesi, elibe selisetshenziswa ukudala izithombe zezakhiwo zangaphakathi zomzimba womuntu.
An Ishubhu le-X-rayiqukethe i-cathode, i-anode kanye ne-vacuum tube. I-cathode ishajwa kabi futhi ivame ukwenziwa nge-tungsten, kuyilapho i-anode ishajwa kahle futhi ivame ukwenziwa ngethusi noma i-tungsten. Lapho i-cathode ishiswa kuze kufike ekushiseni okuphezulu, ama-electron akhishwa futhi asheshiswe aye ku-anode, lapho ashayisana khona nezinto eziqondiwe. Lokhu kushayisana kukhiqiza ama-photon e-X-ray ahamba nge-vacuum tube aye entweni ehlolwayo.
Esinye sezici ezibalulekile ze-X-ray tube yikhono le-anode lokususa ukushisa okukhiqizwa ama-electron ashayisana ne-target. Ama-anode ngokuvamile anokulungiselelwa kwediski ejikelezayo okwenzelwe ukususa ukushisa ngempumelelo ngenkathi kugcinwa ubuqotho besakhiwo sedivayisi. Njengoba ubuchwepheshe be-anode buthuthuka, amashubhu amasha angakhiqiza izithombe zekhwalithi ephezulu ngenkathi edinga ukulungiswa okuncane nokuphila isikhathi eside.
Esinye isici esibalulekile sobuchwepheshe be-X-ray ukulawula ukuchayeka emisebeni. Ngenxa yokuthi ukuchayeka emazingeni aphezulu emisebeni kungaba nemiphumela emibi emzimbeni womuntu, amashubhu e-X-ray anamuhla aklanyelwe ukunciphisa ukuchayeka emisebeni. Isibonelo, amanye amashubhu e-X-ray anezilawuli zokuchayeka ngokuzenzakalela ezilungisa ukuchayeka emisebeni ngokusekelwe ezicini ezifana nosayizi womzimba kanye nohlobo lwezicubu. Lokhu kuphumela ekuthathweni kwezithombe okunembe kakhudlwana kanye nokuchayeka emisebeni okuncane.
Ekugcineni, yesimanjeAmashubhu e-X-rayzinezici eziningi ezengeziwe ezithuthukisa ukusebenza kanye nokusebenziseka kalula. Isibonelo, amanye amashubhu anokugxila okulungisekayo, okuvumela abasebenzisi ukuthi balungise usayizi kanye nesimo somsebe we-X-ray ukuze uvumelane nezidingo zabo ezithile. Amanye amashubhu afakwe uhlelo lokupholisa oluthuthukisiwe lokusetshenziswa isikhathi eside, okunciphisa isikhathi sokungasebenzi kanye nokwandisa ukusebenza kahle.
Ekuphetheni, ubuchwepheshe be-X-ray tube buhambe ibanga elide selokhu basungulwa futhi buyaqhubeka nokukhula nanamuhla. Ngokuthuthuka kobuchwepheshe be-anode, ukulawulwa kokuchayeka emisebeni, kanye namanye amakhono, ubuchwepheshe besimanje buyaqhubeka.Amashubhu e-X-raykuyisenzo esimangalisayo sobunjiniyela esiye savumela ochwepheshe bezokwelapha abaningi ukuthi baxilonge futhi baphathe izifo ezahlukahlukene. Njengoba ubuchwepheshe buqhubeka nokuthuthuka, kuyajabulisa ukucabanga ukuthi intuthuko entsha kwezobuchwepheshe be-X-ray tube izosisiza kanjani esikhathini esizayo.
