Ukwakhiwa komshini we-Medical X-ray -https://hv-caps.biz
Inhliziyo yomshini we-X-ray wezokwelapha i-electrode pair - i-cathode ne-anode - ehlala ngaphakathi kwethubhu yengilazi. I-cathode iyintambo evuthayo, njengoba ungathola kusibani esidala se-fluorescent. Umshini udlula manje ngentambo, uyifudumeze. Ama-heat sputters electron avela ebusweni be-filament. I-anode ekhokhiswe kahle, i-disc eyisicaba eyenziwe nge-tungsten, idonsela ama-electron ngaphesheya kweshubhu.
Umehluko we-voltage phakathi kwe-cathode ne-anode uphezulu kakhulu, ngakho-ke ama-elektroni andiza nge-tube ngamandla amakhulu. Lapho i-elektroni egijima ngokushesha ishayisana ne-athomu elithambile, ingqongqoza i-elektroni kwenye yama-athomu aphansi e-athomu. I-elektroni ese-orbital ephakeme iwela ngokushesha ezingeni eliphansi lamandla, ikhulule amandla ayo owengeziwe ngendlela ye-photon. Ukwehla okukhulu, ngakho-ke i-photon inezinga lamandla aphezulu - iyi-Photon ye-X-ray.
Ama-elekthronikhi amahhala angakwazi nokukhiqiza ama-Photons ngaphandle kokushaya i-athomu. I-athomu ye-athomu ingaheha i-elektroni eshesha ngokwanele nje ukuguqula inkambo yayo. Njengomshayabhuqe oshaya ilanga, i-elektroni yehlisa ijubane futhi iguqule ukuqondisa njengoba ishesha i-athomu. Lesi senzo esithi “braking” senza ukuthi abakwa-elektroni bakhiphe amandla amaningi ngendlela ye-X-ray Photon.
Ukushayisana okunomthelela ophakeme obandakanyeka ekukhiqizeni i-X-ray kukhiqiza ukushisa okuningi. Imoto ijikeleza i-anode ukuze ingahambi ngokuncibilika (ugongolo lwe-elekthronikhi aluhlali lugxile endaweni efanayo). Ibhavu elipholile lamafutha elizungeza imvilophu nalo libamba ukushisa.
Yonke imishini izungezwe isihlangu esikhulu sokuhola. Lokhu kuvimbela ama-X-ray ukubalekela kuzo zonke izinkomba. Iwindi elincane esivivaneni lenza ezinye zezithombe ezingama-X-ray ziphunyuke ugongolo oluncane. Uxhaxha luhamba luchungechunge lokuhlunga lusendleleni eya esigulini.
Ikhamera ngakolunye uhlangothi lwesiguli iqopha iphethini yokukhanya kwe-X-ray edlula yonke indlela emzimbeni wesiguli. Ikhamera ye-X-ray isebenzisa ubuchwepheshe obufanayo bekhamera njengekhamera ejwayelekile, kepha ukukhanya kwe-X-ray kususa ukusabela kwamakhemikhali esikhundleni sokukhanya okubonakalayo.
Ngokuvamile, odokotela bagcina isithombe sefilimu njengesingesihle. Okusho ukuthi, izindawo ezivezwa ukukhanya okungaphezulu zibonakala zimnyama futhi izindawo ezivezwa ukukhanya okungatheni zibonakale zilula. Izinto eziqinile, ezinjengethambo, zibukeka zimhlophe, kanti nezinto ezithambile zibukeka zimnyama noma ziphuzi. Odokotela bangaletha izinsimbi ezahlukahlukene ekugxilwe kuzo ngokuhlukahluka kogongolo lwe-X-ray.
