Kwiinkalo zemifanekiso yezonyango kunye nokuxilongwa, iteknoloji ye-X-ray idlale indima ebalulekileyo kangangamashumi eminyaka.Phakathi kwamacandelo ahlukeneyo enza umatshini we-X-ray, ityhubhu ye-anode esisigxina ye-X-ray ibe yinto ebalulekileyo yezixhobo.Ezi tyhubhu aziboneleli kuphela ngemitha efunekayo kwimifanekiso, kodwa zikwamisela umgangatho kunye nokusebenza kakuhle kwayo yonke inkqubo ye-X-ray.Kule bhlog, siza kuphonononga iintsingiselo kwiityhubhu zeX-reyi ze-anode kunye nendlela inkqubela phambili yobuchwepheshe iguqula ngayo eli candelo libalulekileyo.
Ukususela ekuqaleni ukuya ekuzalweni kwangoku:
Imibhobho yeX-reyi emileyo anodebanembali ende esukela emva kokufunyanwa kweX-reyi nguWilhelm Conrad Roentgen ekuqaleni kwenkulungwane yama-20.Ekuqaleni, iityhubhu zaziquka iglasi evaliweyo elula ehlala i-cathode kunye ne-anode.Ngenxa yeqondo eliphezulu lokunyibilika, i-anode ngokuqhelekileyo yenziwe nge-tungsten, enokuthi ibonakaliswe ekuhambeni kwee-electron ixesha elide ngaphandle komonakalo.
Ngokuhamba kwexesha, njengoko imfuno yomfanekiso ochanekileyo nochanekileyo ikhula, kuye kwenziwa inkqubela phambili enkulu kuyilo nolwakhiwo lweetyhubhu zeX-reyi ezimileyo.Ukuqaliswa kweetyhubhu ze-anode ezijikelezayo kunye nophuhliso lwezixhobo ezinamandla ezivumeleke ukwandisa ukutshatyalaliswa kobushushu kunye nokukhutshwa kwamandla aphezulu.Nangona kunjalo, iindleko kunye nobunzima beetyhubhu ze-anode ezijikelezayo zithintele ukwamkelwa kwazo ngokubanzi, okwenza iityhubhu ze-anode ezimileyo zibe lolona khetho luphambili kumfanekiso wezonyango.
Iintsingiselo zakutsha nje kwiityhubhu zeX-reyi ze-anode:
Kutshanje, uphuculo olubalulekileyo lwetekhnoloji luye lwakhokelela ekuthandeni kwakhona kwi-fixed-anode X-ray tubes.Ezi nkqubela-phambili zinika amandla okucinga okongeziweyo, ukuphuma kwamandla aphezulu, kunye nokumelana nobushushu okukhulu, kuzenza zithembeke ngakumbi kwaye zisebenze ngakumbi kunangaphambili.
Umkhwa ophawulekayo kukusetyenziswa kweentsimbi eziphikisayo ezifana ne-molybdenum kunye ne-tungsten-rhenium alloys njengezinto ze-anode.Ezi zinyithi zinokuxhathisa ubushushu obubalaseleyo, zivumela iityhubhu ukuba zimelane namanqanaba aphezulu ombane kunye namaxesha okuvezwa amade.Olu phuhliso lube negalelo elikhulu ekuphuculeni umgangatho womfanekiso kunye nokunciphisa ixesha lokucinga kwindlela yokuxilonga.
Ukongeza, indlela entsha yokupholisa iye yaziswa ukunika ingxelo malunga nobushushu obuveliswa ngexesha lokukhutshwa kweX-reyi.Ngokudityaniswa kwesinyithi solwelo okanye abaphethe i-anode eyenzelwe ngokukodwa, amandla okutshatyalaliswa kobushushu beetyhubhu ze-anode ezisisigxina ziphuculwe kakhulu, ukunciphisa umngcipheko wokushisa kunye nokwandisa ubomi bubonke beetyhubhu.
Omnye umkhwa ochulumancisayo kukudityaniswa kweetekhnoloji zale mihla zokucinga ezifana nezixhobo zokujonga idijithali kunye ne-algorithms yokusetyenzwa kwemifanekiso eneityhubhu ze-X-ray ze-anode.Oku kudityaniswa kuvumela ukusetyenziswa kobuchule obuphezulu bokufunyanwa kwemifanekiso efana ne-digital tomosynthesis kunye ne-cone beam computed tomography (CBCT), okubangela ukwakhiwa kwakhona kwe-3D echanekileyo kunye nokuxilongwa okuphuculweyo.
ukuququmbela:
Ukuqukumbela, umkhwa oyaimibhobho yeX-reyi emileyo ye-anode isoloko iphuhla ukuze ihlangabezane neemfuno zomfanekiso wezonyango wale mihla.Ukuqhubela phambili kwezixhobo, iindlela zokupholisa, kunye nokudityaniswa kobugcisa bokucinga obuphambili kuye kwaliguqula eli candelo libalulekileyo kwiinkqubo zeX-reyi.Ngenxa yoko, iingcali zezempilo ngoku zinokubonelela izigulana ngomgangatho ongcono womfanekiso, ukuvezwa okuncinci kwemitha kunye nolwazi oluchanekileyo lokuxilonga.Kucacile ukuba iityhubhu ze-X-ray ze-anode ezisisigxina ziya kuqhubeka zidlala indima ephambili kwi-imaging yonyango, ukuqhuba ukutsha kunye negalelo ekuphuculeni ukunakekelwa kwesigulane.
