Ib qho txiaj ntsig tseem ceeb ntawm kev siv daim phiaj X-ray yog nws lub peev xwm los txhim kho cov duab sib piv.Thaum X-ray beam hla lub cev, nws cuam tshuam nrog ntau yam qauv, ua rau ob qho tib si thawj thiab tawg tawg.Thaum cov hluav taws xob tseem ceeb muaj cov ntaub ntawv kuaj mob muaj txiaj ntsig, cov hluav taws xob tawg tawg ua rau cov duab tsis zoo.Los ntawm kev tso ib daim phiaj X-ray nyob rau hauv pem hauv ntej ntawm cov duab receptor, tawg tawg tawg tau zoo absorbed, cia tsuas yog cov tseem ceeb thawj hluav taws xob mus cuag lub detector.Yog li ntawd, qhov sib txawv ntawm cov qauv sib txawv hauv cov duab tau raug txhim kho, ua rau kom pom tseeb thiab pom tseeb dua.

Tsis tas li ntawd, X-ray daim phiaj pab txo qhov muaj cov duab kos duab.Cov khoom cuav yog cov qauv tsis xav tau lossis cov qauv uas tshwm sim hauv cov duab kuaj mob, uas ua rau muaj kev txhais lus tsis raug thiab tsis tsim nyog cov duab ntxiv.Cov tawg tawg tawg tuaj yeem ua rau muaj kev tsim cov khoom qub, xws li kab kab lossis cov duab dab.Los ntawm kev nqus cov hluav taws xob tawg, X-ray daim phiaj txo qis qhov tshwm sim ntawm cov khoom qub, ua rau cov duab huv dua thiab txhim khu kev qha.

Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias kev siv daim phiaj X-ray yuav tsum muaj kev sib raug zoo.Yog hais tias misaligned, cov hlau lead strips ntawm daim phiaj tuaj yeem cuam tshuam thawj cov hluav taws xob, ua rau cov duab tsis tiav thiab cov duab tsis zoo.Yog li ntawd, cov kws tshaj lij xov tooj cua yuav tsum xyuas kom meej tias daim phiaj raug muab tso rau kom raug ua ntej tso tus neeg mob mus rau X-rays.Tsis tas li ntawd, cov phiajcim tuaj yeem qhia qee qhov kev txiav tawm ntawm daim phiaj, uas yog hais txog qhov txo qis hauv thawj cov hluav taws xob uas tau nqus los ntawm cov kab sib chaws misalignment lossis yuam kev hauv lawv qhov tsim.Nws yog ib qho tseem ceeb rau cov kws kho mob kom paub txog cov kev txwv no kom tsis txhob cuam tshuam qhov zoo ntawm X-ray duab.

Hauv kev xaus, kev siv ib qhoX-ray daim phiajho txhim kho qhov tseeb thiab meej ntawm cov duab kuaj mob.Los ntawm kev xaiv absorbing tawg tawg, ib daim phiaj X-ray txhim kho cov duab sib piv thiab txo cov khoom cuav.Txawm li cas los xij, kev sib raug zoo thiab kev nkag siab ntawm cov kev txwv muaj peev xwm yog qhov tseem ceeb rau kev siv kom zoo.Raws li kev siv thev naus laus zis txuas ntxiv mus, nws tau cia siab tias kev txhim kho ntxiv hauv X-ray daim phiaj tsim yuav ua rau cov duab zoo dua qub thiab qhov tseeb ntawm kev kuaj mob hauv thaj chaw kho mob.
