Ososayensi bathuthukise futhi bahlola ngempumelelo ubuchwepheshe obusezingeni eliphezulu obubizwa ngokuthi i-rotation anode X-ray tube, okuwumphumela omkhulu ekuthathweni kwezithombe zezokwelapha. Le ntuthuko entsha inamandla okuguqula ubuchwepheshe bokuxilonga, okwenza kube nokwenzeka ukuthwebula izithombe okunembe kakhulu nokuningiliziwe ukuze kuthuthukiswe ukunakekelwa kweziguli.
Amashubhu e-X-ray avamile abelokhu eyithuluzi elibalulekile ekuxilongweni kwezokwelapha, enikeza ukuqonda okubalulekile ngempilo yesiguli. Kodwa-ke, anemikhawulo lapho ethwebula izithombe zezindawo ezincane noma eziyinkimbinkimbi, njengenhliziyo noma amalunga. Yilapho-keamashubhu e-X-ray e-anode ajikelezayongena emsebenzini.
Ngokuhlanganisa ubunjiniyela obuthuthukisiwe kanye nezinto zesimanje, la mashubhu e-X-ray ajikelezayo asanda kuthuthukiswa ayakwazi ukukhiqiza amandla e-X-ray amaningi kakhulu kunalawo angaphambi kwawo. Lokhu kukhishwa kwamandla okuthuthukisiwe kuvumela odokotela nodokotela be-radiology ukuthi bathwebule izithombe ezicacile nezinemininingwane yezindawo okunzima ukuzifinyelela emzimbeni.
Esinye sezici eziyinhloko zala mashubhu yikhono lawo lokujikeleza ngokushesha, okuthuthukisa ikhwalithi yesithombe. Indlela yokujikeleza isusa ukushisa okukhiqizwa ngesikhathi sokuthwebula izithombe, inciphise ingozi yokushisa ngokweqile futhi yandise impilo yamashubhu. Lokhu kusho ukuthi ochwepheshe bezokwelapha bangenza izinqubo zokuthwebula izithombe ezinde neziyinkimbinkimbi ngaphandle kokuphazamiseka ngenxa yokushisa ngokweqile.
Ngaphezu kwalokho, amashubhu e-X-ray anode ajikelezayo asiza ekunciphiseni amazinga okuvezwa kwemisebe yesiguli uma kuqhathaniswa nemishini ye-X-ray evamile. Lobu buchwepheshe buvumela ukulethwa okuqondiswe kakhulu kwe-X-ray, kunciphisa ukuvezwa okungadingekile ezicutshini nasezithweni zomzimba ezinempilo. Lokhu akugcini nje ngokuthuthukisa ukuphepha kwesiguli, kodwa futhi kunciphisa nemiphumela emibi engaba khona ehlobene nokuvezwa kwemisebe.
Izikhungo zezokwelapha ezihamba phambili emhlabeni wonke sezivele zisebenzisa lobu buchwepheshe obuthuthukisiwe. Ochwepheshe bemisebe kanye nochwepheshe bezokwelapha bayakwazisa imiphumela emangalisayo yokuthwebula izithombe enikezwa ngamapayipi amasha e-X-ray, okubavumela ukuthi bathole futhi baxilonge izimo ngokunemba okukhulu nangokunembile.
UDkt Sarah Thompson, isazi se-radiation esidumile esikhungweni sezokwelapha esidumile, uphawule wathi: "Amashubhu e-X-ray ajikelezayo ashintshe ngempela ikhono lethu lokuxilonga nokwelapha amacala ezokwelapha ayinkimbinkimbi. Izinga lemininingwane esingalibona manje emiphumeleni yezithombe alinakuphikwa ngalobu buchwepheshe Ukuhambisa izithombe zezokwelapha ezingeni elisha ngokuphelele."
Njengoba isidingo sokuxilonga kwezokwelapha okuthuthukile sikhula, ukwethulwa kwe-X-ray tube ye-anode ejikelezayo ngokuqinisekile kuyishintsho elikhulu. Lokhu kuphumelela akugcini nje ngokunika amandla ochwepheshe bezokwelapha, kodwa futhi kuthuthukisa imiphumela yeziguli ngokuvumela ukuxilongwa kusenesikhathi nangokunembile.
Ngocwaningo oluqhubekayo kanye nemizamo yokuthuthukisa, kulindeleke ukuthi ukubuyekezwa kwesikhathi esizayo kwe-ishubhu ye-X-ray ye-anode ejikelezayokuzoletha intuthuko enkulu nakakhulu, kuthuthukiswe insimu yezithombe zezokwelapha, futhi kubekwe izindinganiso ezintsha ekunakekelweni kweziguli.
