Hauv kev sim tshuaj tsis puas tsuaj (NDT), kev tshuaj xyuas X-ray yog ib qho thev naus laus zis tseem ceeb rau kev ntsuam xyuas qhov ncaj ncees ntawm cov khoom siv thiab cov qauv. Lub plawv ntawm cov txheej txheem nyuaj no yog lub raj xa hluav taws xob X-ray hauv kev lag luam, uas yog ib qho tseem ceeb rau kev tsim cov duab X-ray zoo. Tsab xov xwm no yuav nkag siab tob txog kev siv tshuab tshuaj xyuas X-ray thiab piav qhia txog lub luag haujlwm tseem ceeb ntawm cov raj xa hluav taws xob X-ray hauv kev ua kom muaj kev nyab xeeb thiab kev ntseeg tau hauv ntau yam kev lag luam.
Cov raj xa hluav taws xob X-ray rau kev lag luamyog cov khoom siv tshwj xeeb uas tsim los hloov lub zog hluav taws xob mus ua hluav taws xob electromagnetic los tsim cov X-rays. Cov raj no tau tsim los kom tiv taus qhov nyuaj ntawm cov chaw ua haujlwm hauv kev lag luam, muab kev ua haujlwm zoo thiab ruaj khov. Cov raj X-ray hauv kev lag luam feem ntau muaj cathode, anode, thiab lub tshuab nqus tsev uas ua haujlwm ua ke los tsim cov X-rays. Thaum cov electrons uas cathode tso tawm sib tsoo nrog anode, lawv tsim cov X-rays uas tuaj yeem nkag mus rau ntau yam khoom siv, tso cai rau cov neeg soj ntsuam saib xyuas cov qauv sab hauv yam tsis ua rau muaj kev puas tsuaj.
Kev siv tshuab tshuaj xyuas duab X-ray yog hais txog kev txawj ntse ntawm tus neeg ua haujlwm ib yam li nws yog hais txog thev naus laus zis nws tus kheej. Tus kws tshaj lij yuav tsum nkag siab txog cov ntsiab cai ntawm kev thaij duab hluav taws xob, suav nrog kev sib cuam tshuam ntawm cov duab X-ray nrog cov khoom sib txawv, kev teeb tsa qhov chaw raug, thiab kev txhais cov duab. Hom raj X-ray siv rau kev lag luam thiab kev teeb tsa siv thaum lub sijhawm tshuaj xyuas muaj feem cuam tshuam rau qhov zoo ntawm cov duab X-ray. Rau cov txiaj ntsig zoo tshaj plaws, kev kho kom raug ntawm cov yam xws li lub zog hluav taws xob ntawm lub raj, tam sim no, thiab lub sijhawm raug yog qhov tseem ceeb heev.
Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm kev siv cov raj X-ray hauv kev lag luam rau kev tshuaj xyuas yog lawv lub peev xwm los nrhiav cov qhov tsis zoo sab hauv uas cov txheej txheem tshuaj xyuas ib txwm tsis pom. Lub peev xwm no yog qhov tseem ceeb hauv kev lag luam xws li aerospace, tsheb, thiab kev tsim kho, qhov twg txawm tias qhov tsis zoo me tshaj plaws tuaj yeem ua rau muaj kev puas tsuaj loj heev. Los ntawm kev siv kev tshuaj xyuas X-ray, cov tuam txhab tuaj yeem txheeb xyuas cov teeb meem xws li tawg, qhov khoob, thiab cov khoom sib xyaw, kom ntseeg tau tias lawv cov khoom ua tau raws li cov qauv kev nyab xeeb nruj.
Tsis tas li ntawd xwb, kev nce qib hauv kev siv tshuab raj X-ray hauv kev lag luam ua rau muaj kev tsim cov tshuab me me thiab ua haujlwm tau zoo dua. Cov raj X-ray niaj hnub no tau tsim los muab cov duab zoo dua thaum txo qis kev raug hluav taws xob rau tus neeg teb xov tooj thiab ib puag ncig. Kev tsim kho tshiab xws li kev thaij duab digital thiab kev thaij duab computed tomography (CT) tau txhim kho cov peev xwm tshuaj xyuas X-ray ntxiv, ua rau muaj kev tshuaj xyuas ntxaws ntxiv thiab txo lub sijhawm tshuaj xyuas.
Kev koom ua ke ntawm cov raj xa duab X-ray hauv kev lag luam rau hauv cov tshuab tshuaj xyuas tsis siv neeg kuj tau hloov pauv txoj kev siv tshuab tshuaj xyuas X-ray. Kev siv tshuab tsis yog tsuas yog txhim kho kev ua haujlwm zoo xwb tab sis kuj txo qhov ua yuam kev ntawm tib neeg, ua rau muaj cov txiaj ntsig tshuaj xyuas txhim khu kev qha dua. Thaum cov lag luam txuas ntxiv txais yuav kev siv tshuab, qhov kev thov rau cov raj xa duab X-ray hauv kev lag luam ua tau zoo yuav txuas ntxiv loj hlob, tsav tsheb kev nce qib ntawm thev naus laus zis.
Hauv kev xaus, lub luag haujlwm tseem ceeb uas tau ua los ntawmCov raj xa hluav taws xob X-ray rau kev lag luamtau ua kom lub tshuab X-ray zoo dua qub. Cov khoom siv no tsis yog tsuas yog qhov tseem ceeb rau kev tsim cov duab X-ray zoo xwb, tab sis kuj tseem ceeb rau kev ua kom muaj kev nyab xeeb thiab kev ntseeg siab ntawm cov khoom lag luam thoob plaws ntau yam kev lag luam. Thaum thev naus laus zis txuas ntxiv mus, lub peev xwm ntawm cov raj X-ray hauv kev lag luam yuav nthuav dav ntxiv, ua kom muaj txiaj ntsig zoo ntawm kev tshuaj xyuas X-ray hauv kev ua kom muaj kev nyab xeeb rau pej xeem thiab tswj hwm cov qauv kev lag luam. Yav tom ntej ntawm kev tshuaj xyuas X-ray yog qhov ci ntsa iab, thiab hauv nws lub hauv paus yog lub raj X-ray hauv kev lag luam uas tsis tseem ceeb, qhov txuj ci tseem ceeb ntawm kev tsim kho thiab kev tsim kho tshiab.
