Iyini i-anode ejikelezayo? Lo mbuzo uvame ukuvela lapho kuxoxwa ngezici zobuchwepheshe zamashubhu e-X-ray. Kulesi sihloko, sizongena ngokujulile emqondweni we-amashubhu e-X-ray e-anode ajikelezayofuthi uhlole imiphumela yazo ekuthathweni kwezithombe zezokwelapha.
Ukuthwebula izithombe nge-X-ray kushintshe kakhulu umkhakha wezokwelapha ngokuvumela odokotela ukuba babone izakhiwo zangaphakathi ngaphandle kokwenza ukuhlinzwa okuhlaselayo. Amashubhu e-X-ray ayisisekelo sobuchwepheshe futhi akhiqiza ama-X-ray anamandla aphezulu adingekayo kule ndlela yokuthwebula izithombe engahlaseli. I-anode ejikelezayo iyisici esibalulekile sala mashubhu e-X-ray, okwandisa ukusebenza kahle kwawo kanye nobude bawo.
Ngakho-ke, iyini ngempela i-anode ejikelezayo? Kalula nje, iyithagethi emise okwediski eyenziwe ngezinto ze-athomu eziningi njenge-tungsten noma i-molybdenum. Ithagethi ijikeleza ngokushesha ngesikhathi sokukhiqizwa kwe-X-ray, okuvumela ukushabalaliswa kokushisa okuphumelelayo kanye nokwanda kokukhishwa kwe-X-ray.
Inhloso eyinhloko yama-anode ajikelezayo ukunqoba ukulinganiselwa kwama-anode aqinile. Kumashubhu e-X-ray ajwayelekile ane-anode eqondile, ukushisa okukhiqizwa ngesikhathi sokukhiqizwa kwe-X-ray kukhawulelwe endaweni encane ku-anode. Lokhu kushisa okugxilile kuyawohloza ngokushesha i-anode, kunciphise amandla kanye nobude bokukhishwa kwe-X-ray. Ama-anode ajikelezayo axazulula le nkinga ngokusabalalisa umthwalo wokushisa endaweni enkulu, ngaleyo ndlela kuncishiswe ukuguguleka kwe-anode futhi kwandise impilo yamashubhu.
Umklamo wama-anode ajikelezayo uhilela ubunjiniyela obuyinkimbinkimbi. I-anode ivame ukwenziwa nge-tungsten ngoba inephuzu eliphezulu lokuncibilika futhi ingamelana nokushisa okukhulu okukhiqizwa lapho kukhiqizwa ama-X-ray. Ngaphezu kwalokho, i-anode imbozwe ngesendlalelo esincane sezinto eziphikisayo, njenge-graphite noma i-molybdenum, ukuze kuthuthukiswe ukuhanjiswa kwayo kokushisa.
Ukujikeleza kwe-anode kufezwa kusetshenziswa i-rotor nama-bearings. I-rotor eqhutshwa yinjini kagesi ijikeleza i-anode ngesivinini esikhulu, ngokuvamile cishe ukujikeleza okungu-3,000 kuya ku-10,000 ngomzuzu. Ama-bearings aqinisekisa ukujikeleza okubushelelezi nokuzinzile, noma yikuphi ukungalingani noma ukudlidliza kungathinta kabi ikhwalithi yesithombe.
Izinzuzo zamashubhu e-X-ray anode ajikelezayo ziningi. Okokuqala, i-anode ejikelezayo inendawo enkulu engasusa ukushisa kangcono, ngaleyo ndlela yandise izikhathi zokuchayeka futhi yandise umphumela we-X-ray. Lokhu kusho izikhathi zokuhlolwa ezimfushane kanye nenduduzo enkulu yesiguli. Ngaphezu kwalokho, ukuqina kwe-anode ejikelezayo kuvumela ishubhu le-X-ray ukuthi likwazi ukumelana nokusetshenziswa okuphindaphindiwe nokude, okwenza libe yindawo ekahle yezikhungo zezokwelapha ezinomthamo omkhulu.
Ngaphezu kwalokho, ikhono lokugxila umsebe we-X-ray endaweni encane ye-anode kwandisa ukucaca nokucaca kwezithombe ezivelayo. Lokhu kubaluleke kakhulu ekuthathweni kwezithombe, lapho ukubona kahle izakhiwo zomzimba kubalulekile khona. Amandla athuthukisiwe okuhlakaza ukushisa kwe-anode ejikelezayo enza kube lula ukuthwebula izithombe okuqhubekayo ngaphandle kokuphazamiseka kokupholisa, okuthuthukisa ukusebenza kahle komsebenzi.
Ngokufigqiwe,amashubhu e-X-ray e-anode ajikelezayo yaguqula insimu yezithombe zezokwelapha. Ngobunjiniyela bayo obuthuthukisiwe kanye nezakhiwo zayo zokusabalalisa ukushisa ezisezingeni eliphezulu, la mashubhu anikeza izinzuzo eziningi ngaphezu kwamashubhu e-anode aqinile avamile. Kusukela ekukhiqizweni kwe-X-ray okwandisiwe kanye nokuphila kwamashubhu isikhathi eside kuya ekuxazululweni kwesithombe okuthuthukisiwe, amashubhu e-X-ray e-anode ajikelezayo abe yithuluzi elibalulekile ekunakekelweni kwezempilo kwanamuhla.
