Yintoni i-anode ejikelezayo?Lo mbuzo uvame ukuvela xa uxubusha imiba yobugcisa beetyhubhu ze-X-ray.Kweli nqaku, siza kungena nzulu kwingcamango yeezijikelezayo iityhubhu X-reyi anodekwaye baphonononge iziphumo zabo kwimifanekiso yezonyango.
Imifanekiso yeX-reyi iye yaliguqula icandelo lezamayeza ngokuvumela oogqirha ukuba babe nombono wezakhiwo zangaphakathi ngaphandle kokwenza utyando oluhlaselayo.Iityhubhu zeX-reyi zisembindini wethekhinoloji kwaye zivelisa iiX-reyi zamandla aphezulu ezifunekayo kobu buchwephesha bokucinga obungangeneleliyo.I-anode ejikelezayo yinxalenye ephambili yale mibhobho ye-X-ray, ukwandisa ukusebenza kwayo kunye nokuphila ixesha elide.
Ke, yintoni kanye kanye i-anode ejikelezayo?Ukubeka nje ngokulula, kujoliso olumilise idiskhi eyenziwe ngezixhobo zenani eliphezulu leathom ezifana ne-tungsten okanye i-molybdenum.Ithagethi ijikeleza ngokukhawuleza ngexesha le-X-reyi yokuvelisa, ivumela ukutshatyalaliswa kokushisa okusebenzayo kunye nokwanda kwemveliso ye-X-ray.
Injongo ephambili ye-anodes ejikelezayo kukunqoba imida ye-anodes esisigxina.Kwiityhubhu ze-X-ray ze-anode eziqhelekileyo, ubushushu obuveliswa ngexesha le-X-reyi buyaphela kwindawo encinci kwi-anode.Lo bushushu obugxininisiweyo buthoba ngokukhawuleza i-anode, bunciphisa amandla kunye nobude bemveliso ye-X-ray.Ii-anode ezijikelezayo zisombulula le ngxaki ngokusabalalisa umthwalo wobushushu kwindawo enkulu, ngaloo ndlela kuncitshiswa ukunxitywa kwe-anode kunye nokwandisa ubomi betyhubhu.
Uyilo lwe-anode olujikelezayo lubandakanya ubunjineli obunzima.I-anode ngokuqhelekileyo yenziwe nge-tungsten ngenxa yokuba inendawo ephezulu yokunyibilika kwaye inokumelana nobushushu obukhulu obuveliswa xa kuveliswa ii-X-rays.Ukongezelela, i-anode ifakwe ngomgca omncinci wezinto eziphikisayo, ezifana negraphite okanye i-molybdenum, ukuphucula i-thermal conductivity.
Ukujikeleza kwe-anode kufezekiswa ngokusebenzisa i-rotor kunye neebheringi.I-rotor eqhutywa yimoto yombane ijikelezisa i-anode ngesantya esiphezulu, ngokuqhelekileyo malunga ne-3,000 ukuya kwi-10,000 revolutions ngomzuzu.Iibheringi ziqinisekisa ukujikeleza okugudileyo kwaye okuzinzileyo, nakuphi na ukungalingani okanye ukungcangcazela kunokuchaphazela kakubi umgangatho womfanekiso.
Izinto eziluncedo zokujikeleza iityhubhu ze-X-ray ze-anode zininzi.Okokuqala, i-anode ejikelezayo inommandla omkhulu womphezulu onokususa ngcono ubushushu, ngaloo ndlela yandisa amaxesha okuvezwa kunye nokwandisa ukuphuma kwe-X-reyi.Oku kuthetha amaxesha amafutshane eemviwo kunye nentuthuzelo enkulu yesigulana.Ukongezelela, ukuqina kwe-anode ejikelezayo kuvumela ityhubhu ye-X-ray ukuba imelane nokusetyenziswa ngokuphindaphindiweyo kunye nexesha elide, okwenza kube yinto efanelekileyo kwizibonelelo zonyango eziphezulu.
Ukongeza, ukukwazi ukujolisa umqadi we-X-ray kwindawo encinci ye-anode kwandisa isisombululo kunye nokucaca kwemifanekiso eziphumo.Oku kubaluleke ngakumbi kumfanekiso wokuxilonga, apho ukubonwa ngokuchanekileyo kwezakhiwo ze-anatomical kubalulekile.Izakhono eziphuculweyo zokuphelisa ubushushu be-anode ejikelezayo ziququzelela ukucinga ngokuqhubekayo ngaphandle kokuphazamiseka kokupholisa, ukuphucula ngakumbi ukuhamba komsebenzi.
Isishwankathelo,ezijikelezayo iityhubhu X-reyi anode iguqule icandelo lezonyango.Ngobunjineli babo obuphambili kunye neempawu eziphezulu zokulahla ubushushu, ezi ityhubhu zibonelela ngeenzuzo ezininzi ngaphezulu kweetyhubhu ze-anode ezisisigxina.Ukusuka kwimveliso ye-X-reyi eyongeziweyo kunye nobomi betyhubhu obude ukuya kwisisombululo somfanekiso ophuculweyo, iityhubhu ezijikelezayo ze-X-ray ziye zaba sisixhobo esiyimfuneko kukhathalelo lwempilo lwangoku.
