Ama-cathode ajikelezayo Ama-X-ray tubes (ama-Rotating Anode X-Ray Tubes) angumthombo we-X-ray onembile kakhulu wezithombe zezokwelapha nezezimboni. Njengoba igama lawo lisikisela, aqukethe i-cathode ejikelezayo futhi ingenye yezinto ezibalulekile zemishini ye-X-ray.
Ishubhu le-X-ray le-cathode elijikelezayo liqukethe i-cathode, i-anode, i-rotor kanye ne-stator. I-cathode iyinduku yensimbi ekhipha ama-electron ngokushisa, kanti i-anode iphambene nayo futhi iyajikeleza. I-anode yenziwe ngezinto ezisebenzisa ukushisa okuphezulu futhi ineziteshi zamanzi zokupholisa. I-anode ivame ukwenziwa ngensimbi ephikisayo njenge-tungsten, i-molybdenum, noma i-platinum, emelana nokushisa kanye nomonakalo wemisebe evela kuma-X-ray anamandla aphezulu.
Uma umsebe we-electron ushaya ubuso be-cathode, ama-electron ayashiswa futhi akhululwe. Lawa ma-electron asheshiswa aye ku-anode, lapho encishiswa khona futhi ahlakazeke, akhiqize imisebe ye-X-ray enamandla aphezulu. I-anode ejikelezayo isabalalisa ngokulinganayo ukushisa okukhiqizwayo kuyo yonke indawo ye-anode, futhi iyipholise ngomsele wamanzi ukuqinisekisa ukuzinza nokuthembeka kokusetshenziswa kwesikhathi eside.
Amashubhu e-X-ray e-cathode ajikelezayo anezinzuzo eziningi, okuhlanganisa amandla aphezulu, imisebe ye-X-ray enamandla aphezulu, ukugxila okuphezulu kwamandla kagesi, isilinganiso esiphezulu sesignali nomsindo, ikhono lokuzivumelanisa nezidingo ezahlukene zezithombe, kanye nokuphila isikhathi eside kwenkonzo. Ngakho-ke, iwumthombo we-X-ray okhethwayo emikhakheni efana nokuthwebula izithombe kwezokwelapha, ukutholwa kwamaphutha e-CT ezimbonini, kanye nokuhlolwa okungonakalisi.
Ngamafuphi, ithubhu le-X-ray elijikelezayo le-cathode liwumthombo we-X-ray onamandla aphezulu, ozinzile futhi othembekile ohlinzeka ngezithombe ze-X-ray ezinembile, ezisezingeni eliphezulu nezinesisombululo esiphezulu zezinhlobo eziningi ezahlukene zezinhlelo zokusebenza zezithombe.
