Amashubhu e-X-ray e-cathode ezungezayo (Amashubhu e-X-Ray e-Anode) angumthombo we-X-ray onembe kakhulu wokuthwebula izithombe zezokwelapha nezimboni.Njengoba igama layo libonisa, iqukethe i-cathode ejikelezayo futhi ingenye yezinto ezibalulekile zemishini ye-X-ray.
Ishubhu ye-X-ray ye-cathode ejikelezayo iqukethe i-cathode, i-anode, i-rotor kanye ne-stator.I-cathode iyinduku yensimbi ekhipha ama-electron ngokwe-thermoelectrically, futhi i-anode iphambene nayo futhi ijikeleza nxazonke.I-anode yenziwe ngezinto eziphezulu ze-thermal conductivity futhi ineziteshi zamanzi zokupholisa.I-anode ngokuvamile yenziwa ngensimbi ephikisayo efana ne-tungsten, i-molybdenum, noma i-platinum, ekwazi ukumelana nokushisa nokulimala kwemisebe evela kuma-X-ray anamandla amakhulu.
Lapho i-electron beam ishaya ebusweni be-cathode, ama-electron ayashiswa futhi akhululwe.Lawa ma-electron asheshiselwa ku-anode, lapho ehlehliswa khona futhi ahlakazeke, akhiqize imisebe ye-X-ray enamandla kakhulu.I-anode ejikelezayo isakaza ngokulinganayo ukushisa okukhiqizwa kuyo yonke indawo ye-anode, futhi ipholise ngomgudu wamanzi ukuze kuqinisekiswe ukuzinza nokuthembeka kokusetshenziswa kwesikhathi eside.
Amashubhu e-X-ray e-cathode ajikelezayo anezinzuzo eziningi, okuhlanganisa amandla aphezulu, imisebe ye-X-ray enamandla kakhulu, amandla amanje agxile kakhulu, isilinganiso esiphezulu sesignali-kuya-nomsindo, ikhono lokuzivumelanisa nezidingo ezihlukahlukene zezithombe, nempilo ende yesevisi.Ngakho-ke, iwumthombo we-X-ray oyikhethayo emikhakheni efana ne-imaging yezokwelapha, ukutholwa kwamaphutha e-CT yezimboni, nokuhlola okungalimazi.
Kafushane, ithubhu ye-X-ray ye-cathode iwumthombo we-X-ray onamandla, ozinzile futhi onokwethenjelwa ohlinzeka ngezithombe ze-X-ray ezinembile, ezisezingeni eliphezulu nezinokulungiswa okuphezulu kwezinhlobo eziningi zezinhlelo zokusebenza zesithombe.
