An Xoo hluav taws xobUa lub luag haujlwm tseem ceeb hauv kev kho mob kev ua haujlwm, kev pab hauv kev tsim cov duab zoo. Raws li thev naus laus zis txuas ntxiv mus ua ntej, qhov xav tau ntawm kev txhim kho kev ua kom zoo dua qub tau dhau los ua ib qho tseem ceeb. Kab lus no yuav tshawb txog lub luag haujlwm ntawm X-ray daim phiaj hauv kev txhim kho qhov raug thiab pom tseeb ntawm x-ray duab.
Ib daim phiaj xoo x-ray, tseem hu ua aBucky Daim phiaj, yog ib qho cuab yeej siv nyob rau hauv radoregraphy los txhim kho kom zoo ntawm x-ray cov duab. Nws muaj cov kab txhuas nyias nyias uas tau ua raws li cov qauv hauv Crisscross, nrog radiolucent interspace cov khoom nyob nruab nrab. Lub luag haujlwm tseem ceeb ntawm daim phiaj yog nqus hluav taws xob hluav taws xob ua ntej nws mus txog cov duab recteror, yog li txo tus nqi ntawm kev pab rau cov duab degradation.
Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm kev siv X-Ray Grid yog nws lub peev xwm los txhim kho cov duab sib piv. Thaum ib lub xoo hluav taws xob nqaj hla dhau ntawm lub cev, nws cuam tshuam nrog ntau yam qauv, ua rau pom kev loj thiab tawg. Thaum lub teeb hluav taws xob qub yuav ua rau cov ntaub ntawv kuaj kuaj mob, tawg hluav taws xob tradiation ib txwm ua rau degrade duab zoo. Los ntawm kev tso X-ray kab sib chaws pem hauv ntej ntawm cov duab receptor, tawg hluav taws xob ua tau zoo nqus, tso cai tsuas yog muaj txiaj ntsig ua ntej hluav taws xob kom ncav cuag cov ntes. Raws li qhov sib piv, qhov sib piv ntawm cov qauv sib txawv hauv cov duab raug txhim kho, ua rau pom meej thiab muaj qhov tseeb.
Ntxiv mus, ib daim ntawv X-ray pab txo cov duab kos duab. Cov khoom cuav yog qhov tsis xav tau lossis cov qauv uas tshwm sim hauv cov duab kev kuaj mob, muaj peev xwm ua rau tsis ncaj ncees thiab kev xav tau ntxiv. Scatterted Radiation tuaj yeem pab rau kev tsim cov khoom cuav, xws li cov kab sib chaws lossis cov duab dab. Los ntawm kev nqus tau qhov hluav taws xob hluav taws xob tawg tag nrho, xoo hluav taws xob cov phiaj xwm txo qhov tshwm sim ntawm cov khoom cuav, ua rau muaj cov duab huv thiab ntau dua.
Nws yog ib qho tseem ceeb kom nco ntsoov tias kev siv X-ray daim phiaj yuav tsum tau ua kom tsim nyog. Yog hais tias misaligned, cov taug txhuas coj ntawm daim phiaj yuav ua rau pom thawj tawg, ua rau cov duab tsis tiav thiab tsis zoo. Yog li ntawd, lub tebchaw yuav tsum ua kom ntseeg tau tias daim phiaj yog muab tso kom raug ua ntej nthuav tawm tus neeg mob rau xoo hluav taws xob. Ib qho ntxiv, cov kab ke tuaj yeem qhia qee qhov kev txiav plaub pob zeb txiav, uas yog hais txog kev txo qis hauv kev sib tw ua haujlwm los yog qhov yuam kev hauv lawv tus qauv. Nws yog qhov tseem ceeb rau cov kws kho mob kom paub txog cov kev txwv no kom tsis txhob ua qhov zoo tshaj plaws ntawm X-ray duab.
Hauv kev xaus, kev siv ntawm ibXoo hluav taws xobTseem ceeb txhim kho qhov tseeb thiab kev pom tseeb ntawm cov duab kuaj mob. Los ntawm xaiv nqus hluav taws xob hluav taws xob hluav taws xob, ib qho X-ray daim phiaj txhim kho cov duab sib txawv thiab txo cov duab kos. Txawm li cas los xij, kho kom raug thiab kev nkag siab ntawm cov peev xwm kev txwv yog qhov tseem ceeb rau kev siv kev ua tau zoo. Raws li thev naus laus zis txuas ntxiv mus ua ntej, nws yog xav tias kev txhim kho ntxiv ntawm X-Ray kev tsim qauv yuav pab rau cov duab zoo dua thiab kev kuaj mob hauv thaj chaw ntawm kev kho mob.
