I-Rotating Anode X-Ray Tubes: Ukubhekisisa izinto ezintsha zobuchwepheshe

I-Rotating Anode X-Ray Tubes: Ukubhekisisa izinto ezintsha zobuchwepheshe

Iyini i-anode ejikelezayo? Lo mbuzo uvame ukuvela lapho kuxoxwa ngezici zobuchwepheshe zamashubhu e-X-ray. Kulesi sihloko, sizongena sijule ngomqondo weamashubhu e-X-ray anode ajikelezayofuthi uhlole imithelela yazo emfanekisweni wezokwelapha.

Ukuthwebula izithombe nge-X-ray kuye kwawushintsha kakhulu umkhakha wezokwelapha ngokuvumela odokotela ukuba babone ngeso lengqondo ukwakheka kwangaphakathi ngaphandle kokuhlinzwa okuhlaselayo. Amashubhu e-X-ray asenhliziyweni yobuchwepheshe futhi akhiqiza ama-X-reyi anamandla adingekayo kule nqubo yokuthwebula engahlanyisi. I-anode ejikelezayo iyingxenye eyinhloko yala mashubhu e-X-ray, okwandisa ukusebenza kahle kwawo nokuphila isikhathi eside.

Ngakho-ke, iyini ngempela i-anode ejikelezayo? Kalula nje, iyithagethi emise okwediski eyenziwe ngezinto zenombolo ye-athomu ephezulu njenge-tungsten noma i-molybdenum. Okuhlosiwe kuzungeza ngokushesha phakathi nokukhiqizwa kwe-X-ray, okuvumela ukuchithwa kokushisa okuphumelelayo nokwandisa ukuphuma kwe-X-ray.

Inhloso eyinhloko yokuzungezisa ama-anode ukunqoba ukulinganiselwa kwama-anode angaguquki. Kumashubhu e-X-ray e-anode avamile, ukushisa okukhiqizwa phakathi nokukhiqizwa kwe-X ray kukhawulelwe endaweni encane ku-anode. Lokhu kushisa okugxilile kwehlisa ngokushesha i-anode, kunciphise amandla nobude besikhathi sokuphuma kwe-X-ray. Ama-anode ajikelezayo axazulula le nkinga ngokusabalalisa umthwalo wokushisa endaweni enkulu, ngaleyo ndlela kuncishiswe ukuguga kwe-anode nokwelula impilo yeshubhu.

Ukwakhiwa kwama-anode ajikelezayo kuhilela ubunjiniyela obuyinkimbinkimbi. I-anode ngokuvamile yenziwe nge-tungsten ngenxa yokuthi inephuzu eliphezulu lokuncibilika futhi ingakwazi ukumelana nokushisa okunamandla okukhiqizwa lapho kukhiqizwa ama-X-ray. Ngaphezu kwalokho, i-anode imbozwe ngendwangu encane yezinto eziphikisayo, njenge-graphite noma i-molybdenum, ukuze kuthuthukiswe ukuqhutshwa kwayo okushisayo.

Ukujikeleza kwe-anode kufinyelelwa ngokusebenzisa i-rotor nama-bearings. Irotha eshayelwa yinjini kagesi izungeza i-anode ngesivinini esikhulu, ngokuvamile cishe ama-revolution angu-3,000 kuya kwangu-10,000 ngomzuzu. Amabhereli aqinisekisa ukuzungezisa okushelelayo nokuzinzile, noma yikuphi ukungalingani noma ukudlidliza kungaba nomthelela omubi kwikhwalithi yesithombe.

Izinzuzo zokuzungezisa amashubhu e-X-ray anode ziningi. Okokuqala, i-anode ejikelezayo inendawo enkulu engaphezulu engasusa kangcono ukushisa, ngaleyo ndlela yandise izikhathi zokuchayeka futhi yandise ukuphuma kwe-X-ray. Lokhu kusho izikhathi ezimfushane zokuhlolwa kanye nokunethezeka okukhulu kwesiguli. Ukwengeza, ukuqina kwe-anode ejikelezayo kuvumela ishubhu ye-X-ray ukuthi imelane nokusetshenziswa okuphindaphindiwe nesikhathi eside, okuyenza ibe ilungele izikhungo zezokwelapha ezinevolumu ephezulu.

Ukwengeza, ikhono lokugxilisa i-X-ray beam endaweni encane ye-anode kwandisa ukulungiswa nokucaca kwezithombe eziwumphumela. Lokhu kubaluleke kakhulu ekucabangeni kokuxilonga, lapho ukubonwa okunembile kwezakhiwo ze-anatomical kubalulekile. Amandla athuthukisiwe okukhipha ukushisa e-anode ejikelezayo enza kube lula ukuthwebula izithombe ngaphandle kweziphazamiso zokupholisa, okuqhubeka nokuthuthukisa ukusebenza kahle kokusebenza.

Ngokufigqiwe,amashubhu e-X-ray anode ajikelezayo yaguqula umkhakha wezithombe zezokwelapha. Ngobunjiniyela bawo obuthuthukisiwe kanye nezakhiwo eziphakeme zokuqeda ukushisa, lawa mashubhu anikeza izinzuzo eziningi ngaphezu kwamashubhu e-anode angaguquki endabuko. Ukusuka ekuphumeni okwandayo kwe-X ray nempilo ende yeshubhu kuya ekulungisweni kwesithombe okuthuthukisiwe, amashubhu e-X-ray e-anode aphendukayo abe yithuluzi elibalulekile ekunakekelweni kwezempilo kwanamuhla.
