Emkhakheni wokuthwebula izithombe zezokwelapha nokuxilongwa, ubuchwepheshe be-X-ray buye badlala indima ebalulekile amashumi eminyaka. Phakathi kwezingxenye ezihlukahlukene ezakha umshini we-X-ray, ishubhu ye-X-ray ye-anode engashintshi isibe ingxenye ebalulekile yemishini. Lawa mashubhu awanikezi nje kuphela imisebe edingekayo ukuze kuthathwe izithombe, kodwa futhi anqume izinga nokusebenza kahle kwalo lonke uhlelo lwe-X-ray. Kule bhulogi, sizohlola izitayela kumashubhu e-X-ray anode engashintshi nokuthi intuthuko yezobuchwepheshe iyishintsha kanjani le ngxenye ebalulekile.
Kusukela ekuqaleni kuze kube yimanje:
Amashubhu e-X-ray anode emilebanomlando omude osukela ekutholweni kokuqala kwamaX-ray nguWilhelm Conrad Roentgen ekuqaleni kwekhulu lama-20. Ekuqaleni, amashubhu ayehlanganisa ingilazi elula ebiyelwe efaka i-cathode ne-anode. Ngenxa yezinga layo eliphakeme lokuncibilika, i-anode ivame ukwenziwa nge-tungsten, engavezwa ekuhambeni kwama-electron isikhathi eside ngaphandle kokulimala.
Ngokuhamba kwesikhathi, njengoba isidingo sokuthwebula isithombe esinembe kakhudlwana nesinembile sikhula, kuye kwaba nentuthuko enkulu ekwakhiweni nasekukhiweni kwamashubhu e-X-ray anode amile. Ukwethulwa kwamashubhu e-anode azungezayo kanye nokuthuthukiswa kwezinto eziqinile kuvunyelwe ukwandisa ukuchithwa kokushisa kanye nokukhishwa kwamandla aphezulu. Kodwa-ke, izindleko nobunkimbinkimbi bamashubhu e-anode azungezayo kukhawulele ukutholwa kwawo okusabalele, okwenza amashubhu e-anode amile abe yisinqumo esiyinhloko sokuthwebula isithombe sezokwelapha.
Amathrendi akamuva kumashubhu e-X-ray anode angashintshi:
Muva nje, ukuthuthukiswa okuphawulekayo kwezobuchwepheshe kuholele ekuvuseleleni ukuthandwa kwamashubhu e-X-ray e-anode ehleliwe. Lokhu kuthuthuka kunika amandla amandla okuthwebula athuthukisiwe, ukuphuma kwamandla aphezulu, nokumelana nokushisa okukhulu, okuwenza athembeke futhi asebenze kahle kunangaphambili.
Umkhuba ophawulekayo ukusetshenziswa kwezinsimbi eziphikisayo ezifana ne-molybdenum ne-tungsten-rhenium alloys njengezinto ze-anode. Lezi zinsimbi zinokumelana nokushisa okuhle kakhulu, okuvumela amashubhu ukuthi amelane namazinga aphezulu wamandla kanye nezikhathi zokuchayeka ezinde. Lokhu kuthuthukiswa kube negalelo elikhulu ekuthuthukisweni kwekhwalithi yesithombe kanye nokunciphisa isikhathi sokuthatha izithombe ohlelweni lokuxilonga.
Ukwengeza, indlela yokupholisa entsha yethuliwe ukuze ichaze ukushisa okukhiqizwa ngesikhathi sokukhishwa kwe-X-ray. Ngokungezwa kwensimbi ewuketshezi noma izibambi ze-anode eziklanywe ngokukhethekile, amandla okukhipha ukushisa kwamashubhu e-anode angashintshi athuthukiswa kakhulu, kuncishiswe ubungozi bokushisa ngokweqile nokwelula impilo yonke yamashubhu.
Omunye umkhuba othokozisayo ukuhlanganiswa kobuchwepheshe besimanje bokucabanga obufana nezitholi zedijithali nama-algorithms okucubungula izithombe namashubhu e-X-ray anode angashintshi. Lokhu kuhlanganiswa kuvumela ukusetshenziswa kwezindlela ezithuthukisiwe zokuthola izithombe ezifana ne-digital tomosynthesis kanye ne-cone beam computed tomography (CBCT), okuholela ekwakhiweni kabusha kwe-3D okunembe kakhudlwana kanye nokuxilongwa okuthuthukisiwe.
Ekuphetheni:
Sengiphetha, umkhuba obhekeamashubhu e-X-ray anode emile ilokhu ivela njalo ukuze ihlangabezane nezidingo zezithombe zesimanje zezokwelapha. Ukuthuthuka kwezinto zokwakha, izindlela zokupholisa, nokuhlanganiswa kobuchwepheshe bezithombe ezisezingeni eliphezulu kuye kwayiguqula le ngxenye ebalulekile yezinhlelo ze-X-ray. Ngenxa yalokho, ochwepheshe bezokunakekelwa kwempilo manje sebengakwazi ukunikeza iziguli ikhwalithi yesithombe engcono, ukuchayeka emisebeni okuncane kanye nolwazi lokuxilonga olunembayo. Kuyacaca ukuthi amashubhu e-X-ray e-anode angashintshi azoqhubeka edlala indima ebalulekile ekucabangeni kwezokwelapha, ukushayela emisha kanye nokufaka isandla ekunakekelweni kwesiguli okuthuthukisiwe.
