Iityhubhu ze-X-ray ze-cathode ezijikelezayo (IiThubhu ze-X-Ray ezijikelezayo ze-Anode) ngumthombo we-X-reyi ochaneke kakhulu womfanekiso wezonyango kunye noshishino. Njengoko igama layo libonisa, iqulethe i-cathode ejikelezayo kwaye yenye yezinto eziphambili zezixhobo ze-X-ray.
Umbhobho we-X-ray ojikelezayo we-cathode uqukethe i-cathode, i-anode, i-rotor kunye ne-stator. I-cathode yintonga yentsimbi ekhupha ii-electron thermoelectrically, kwaye i-anode ichasene nayo kwaye ijikeleza ngeenxa zonke. I-anode yenziwe ngezinto eziphezulu ze-thermal conductivity kwaye ineendlela zamanzi zokupholisa. I-anode ngokuqhelekileyo yenziwe ngentsimbi ephikisayo efana ne-tungsten, i-molybdenum, okanye iplatinam, ekwazi ukumelana nobushushu kunye nomonakalo wemitha evela kwi-X-rays yamandla aphezulu.
Xa umqa we-electron ubetha umphezulu we-cathode, ii-electron ziyafudumala kwaye zikhutshwe. Ezi electron zikhawuleza ukuya kwi-anode, apho ziyancipha kwaye zisasazeke, zivelisa imitha ye-X-reyi ephezulu. I-anode ejikelezayo isasaza ukushisa okwenziwa kwindawo yonke ye-anode, kwaye ipholise ngomjelo wamanzi ukuqinisekisa ukuzinza nokuthembeka kokusetyenziswa kwexesha elide.
Iityhubhu ze-X-ray ze-cathode ezijikelezayo zineenzuzo ezininzi, kubandakanywa amandla aphezulu, i-ray-ray ye-X-ray ephezulu, ukugxila okuphezulu okwangoku, umlinganiselo ophezulu we-signal-to-noise ratio, ukukwazi ukuziqhelanisa neemfuno ze-imaging, kunye nobomi benkonzo ende. Ke ngoko, ngumthombo weX-reyi okhethwayo kwiinkalo ezinje ngemifanekiso yezonyango, ukufumanisa isiphene se-CT yeshishini, kunye novavanyo olungonakalisi.
Isishwankathelo, ityhubhu ye-X-ray ye-cathode yi-X-ray enamandla, ezinzileyo kwaye enokwethenjelwa yomthombo we-X-ray onika ngokuchanekileyo, umgangatho ophezulu kunye nokulungiswa kwemifanekiso ye-X-ray kwiindidi ezininzi zezicelo ze-imaging.
