Iityhubhu ze-X-ray ezijikelezayo (iityhubhu ze-X-ray ezijikelezayo ze-Anode X-Ray) zingumthombo we-X-ray ochanekileyo kakhulu kwimifanekiso yezonyango neyemizi-mveliso. Njengoko igama layo lisitsho, ine-cathode ejikelezayo kwaye yenye yezona zinto zibalulekileyo kwizixhobo ze-X-ray.
Ityhubhu ye-X-ray ye-cathode ejikelezayo ine-cathode, i-anode, i-rotor kunye ne-stator. I-cathode yintonga yesinyithi ekhupha ii-electron ngobushushu, kwaye i-anode ichasene nayo kwaye ijikeleza kuyo. I-anode yenziwe ngezinto eziphezulu zokuqhuba ubushushu kwaye inemijelo yamanzi yokupholisa. I-anode idla ngokwenziwa ngesinyithi esirhabaxa esifana ne-tungsten, i-molybdenum, okanye i-platinum, esimelana nobushushu kunye nomonakalo wemitha evela kwi-X-rays enamandla aphezulu.
Xa umqadi we-electron ubetha umphezulu we-cathode, ii-electron ziyafudunyezwa zize zikhutshwe. Ezi electron zikhawuleziswa ziye kwi-anode, apho zincitshiswa khona kwaye zisasazeke, zivelisa imitha ye-X-ray enamandla aphezulu. I-anode ejikelezayo isasaza ngokulinganayo ubushushu obuvelisiweyo kumphezulu wonke we-anode, ize ibupholise ngomjelo wamanzi ukuqinisekisa uzinzo kunye nokuthembeka kokusetyenziswa ixesha elide.
Iityhubhu ze-X-ray ze-cathode ezijikelezayo zinezibonelelo ezininzi, kubandakanya amandla aphezulu, imitha ye-X-ray enamandla aphezulu, umbane ogxile kakhulu, umlinganiselo ophezulu wesignali-kwingxolo, ukukwazi ukuziqhelanisa neemfuno ezahlukeneyo zomfanekiso, kunye nobomi benkonzo ende. Ke ngoko, ngumthombo we-X-ray okhethwayo kwiinkalo ezifana nemifanekiso yezonyango, ukufunyanwa kweziphene ze-CT kwimizi-mveliso, kunye novavanyo olungonakalisiyo.
Ngamafutshane, ityhubhu ye-X-ray ye-cathode ejikelezayo ngumthombo we-X-ray onamandla aphezulu, ozinzileyo nothembekileyo obonelela ngemifanekiso ye-X-ray echanekileyo, esemgangathweni ophezulu nenesisombululo esiphezulu kwiintlobo ezahlukeneyo zezicelo zemifanekiso.
