Ngokuthuthuka kwesayensi nobuchwepheshe nokuthuthukiswa kobuchwepheshe bezokwelapha, ayanda kakhulu amathuba okuthi abantu bahlolwe i-X-ray uma beya esibhedlela.Wonke umuntu uyazi ukuthi i-X-ray yesifuba, i-CT, i-color ultrasound kanye ne-X-ray imishini ingakhipha ama-X-ray ukuze ingene emzimbeni womuntu ukuze ibone lesi sifo.Bayazi futhi ukuthi ama-X-ray akhipha imisebe, kodwa bangaki abantu abayiqonda ngempela imishini ye-X-ray.Kuthiwani ngemisebe ekhishwayo?
Okokuqala, anjani ama-X-ray ku-anUmshini we-X-raykukhiqizwa?Izimo ezidingekayo ukuze kukhiqizwe ama-X-ray asetshenziswa kwezokwelapha zimi kanje: 1. Ishubhu le-X-ray: ishubhu yengilazi yokuhlanza equkethe ama-electrode amabili, i-cathode ne-anode;2. Ipuleti le-Tungsten: i-tungsten yensimbi enenombolo ye-athomu ephezulu ingasetshenziswa ukwenza amashubhu e-X-ray I-anode iyimpoqo yokuthola ukuqhuma kwama-electron;3. Ama-electron ahamba ngesivinini esikhulu: sebenzisa amandla kagesi aphezulu kuzo zombili iziphetho zeshubhu ye-X-ray ukuze wenze ama-electron ahambe ngesivinini esikhulu.Ama-transformer akhethekile akhuphula i-voltage ephilayo ibe namandla aphezulu adingekayo.Ngemva kokuba ipuleti le-tungsten lishaywe ama-electron ahamba ngesivinini esikhulu, ama-athomu e-tungsten angenziwa ionized abe ama-electron ukuze akhe ama-X-ray.
Okwesibili, injani le X-ray, futhi kungani ingasetshenziswa ukubheka isimo ngemva kokungena emzimbeni womuntu?Konke lokhu kungenxa yezakhiwo ze-X-ray, ezinezakhiwo ezintathu ezinkulu:
1. Ukungena: Ukungena kubhekisela emandleni e-X-ray ukudlula entweni ngaphandle kokumuncwa.Ama-X-ray angangena ezintweni ukukhanya okuvamile okungenakukwazi ukungena kuzo.Ukukhanya okubonakalayo kunobude beza obude, futhi ama-photon anamandla amancane kakhulu.Uma ishaya into, ingxenye yayo iyavezwa, iningi layo limuncwa izinto, futhi alikwazi ukudlula entweni;kuyilapho ama-X-ray engekho, ngenxa yobude bawo obufushane, amandla Lapho kukhanya phezu kwezinto, ingxenye kuphela emuncwa izinto, futhi iningi layo lidluliselwa ngegebe le-athomu, libonisa ikhono elinamandla lokungena.Ikhono lama-X-ray lokungena ezintweni lihlobene namandla e-X-ray photon.Lapho ubude begagasi be-X ray buba mfishane, amandla ama-photon aba makhulu futhi aba namandla okungena.Amandla angena e-X-ray nawo ahlobene nokuminyana kwezinto.Izinto eziminyene zimunca ama-X-ray amaningi futhi zidlulise kancane;impahla eminyene imunca kancane futhi idlulise okuningi.Ngokusebenzisa le mpahla yokumuncwa okuhlukile, kungahlukaniswa izicubu ezithambile ezinjengamathambo, imisipha, namafutha anobunzima obuhlukahlukene.Lesi yisisekelo esingokomzimba se-X-ray fluoroscopy nokuthatha izithombe.
2. I-ionization: Uma into ikhanyiswa ngama-X-ray, ama-electron e-extranuclear akhishwa ku-athomu ejikelezayo.Lo mphumela ubizwa ngokuthi i-ionization.Enqubweni yomphumela we-photoelectric nokusabalalisa, inqubo lapho ama-photoelectrons nama-recoil electron ahlukaniswa nama-athomu awo ibizwa ngokuthi i-ionization eyinhloko.Lawa ma-photoelectrons noma ama-recoil electron ashayisana namanye ama-athomu ngenkathi ehamba, ukuze ama-electron asuka kuma-athomu ashaywe abizwe nge-ionization yesibili.kokuqinile noketshezi.Ama-ion a-ionized positive and negative azohlangana ngokushesha futhi akulula ukuwaqoqa.Kodwa-ke, ukushaja kwe-ionized kugesi kulula ukuqoqa, futhi inani le-ionized charge lingasetshenziswa ukucacisa inani lokuchayeka kwe-X-ray: Izinsimbi zokulinganisa ze-X-ray zenziwa ngokusekelwe kulesi simiso.Ngenxa ye-ionization, amagesi angakwazi ukuqhuba ugesi;izinto ezithile zingabhekana nokusabela kwamakhemikhali;imiphumela ehlukahlukene yezinto eziphilayo ingenziwa ezintweni eziphilayo.I-ionization iyisisekelo sokulimala nokwelashwa kwe-X-ray.
3. I-Fluorescence: Ngenxa yobude obufushane begagasi be-X ray, ayibonakali.Kodwa-ke, lapho ikhanyiswe ngezinhlanganisela ezithile ezifana ne-phosphorus, i-platinum cyanide, i-zinc cadmium sulfide, i-calcium tungstate, njll., ama-athomu asesimweni sokujabula ngenxa ye-ionization noma ukujabula, futhi ama-athomu abuyela esimweni esiphansi phakathi nenqubo. , ngenxa yokuguqulwa kwezinga lamandla lama-electron e-valence.Ikhipha ukukhanya okubonakalayo noma kwe-ultraviolet, okuyi-fluorescence.Umthelela we-X-ray obangela izinto ukuba zibe ne-fluoresce ubizwa ngokuthi i-fluorescence.Amandla e-fluorescence alingana nenani lama-X ray.Lo mphumela uyisisekelo sokusetshenziswa kwe-X-ray ku-fluoroscopy.Emsebenzini wokuxilonga we-X-ray, lolu hlobo lwe-fluorescence lungasetshenziswa ukwenza isikrini se-fluorescent, isikrini esiqinisayo, isikrini sokufaka ku-intensifier yesithombe nokunye.Isikrini se-fluorescent sisetshenziselwa ukubuka izithombe ze-X-ray edlula esicutshini somuntu ngesikhathi se-fluoroscopy, futhi isikrini esiqinisayo sisetshenziselwa ukuthuthukisa ukuzwela kwefilimu ngesikhathi sokuthwebula izithombe.Okungenhla yisingeniso esijwayelekile se-X ray.
