Thaum nws los txog rau kev kuaj mob, X-ray tshuab yog ib qho cuab yeej tseem ceeb uas tuaj yeem muab cov ntaub ntawv kuaj mob tseem ceeb.X-ray tshuab muaj ntau yam khoom siv, thiab ib qho tseem ceeb yog qhovX-ray daim phiaj.X-ray daim phiaj siv los txhim kho cov duab zoo los ntawm kev txo cov hluav taws xob tawg thiab txhim kho cov duab sib piv.Xaiv txoj cai X-ray kab sib chaws rau kojX-ray tshuabNws yog ib qho tseem ceeb los xyuas kom meej qhov tseeb thiab meej imaging.Hauv tsab xov xwm no, peb yuav tham txog cov xwm txheej uas yuav tsum xav txog thaum xaiv daim phiaj X-ray rau koj lub tshuab X-ray.
Ua ntej peb delve rau hauv cov txheej txheem xaiv, cia peb nkag siab lub hauv paus ntawm X-ray daim phiaj.X-ray kab sib chaws yog ib qho cuab yeej ua los ntawm cov hlau lead nyias hloov nrog cov khoom siv hluav taws xob.Lub luag haujlwm tseem ceeb ntawm daim phiaj yog nqus cov hluav taws xob tawg uas tshwm sim thaum X-ray photons cuam tshuam nrog tus neeg mob lub cev.Cov hluav taws xob tawg tuaj yeem txo cov duab zoo los ntawm kev tsim cov keeb kwm yav dhau los hu ua "grid kab."Los ntawm kev nqus hluav taws xob tawg, X-ray daim phiaj pab txhim kho cov duab sib piv, ua rau cov duab zoo dua.
Qhov tseem ceeb tshaj plaws los xav txog thaum xaiv X-ray kab sib chaws yog nws qhov piv.Daim phiaj sib piv yog hais txog qhov siab ntawm cov hlau lead strips piv rau qhov kev ncua deb ntawm lawv.Cov kab sib faib feem ntau yog 6: 1, 8: 1, 10: 1, thiab 12: 1.Cov kab sib npaug siab dua muab kev nqus hluav taws xob zoo dua tab sis yuav tsum muaj cov txheej txheem X-ray tube ntau dua.Feem ntau, 10: 1 lossis 12: 1 daim phiaj sib piv yog qhov zoo tagnrho rau kev siv hluav taws xob dav dav, vim nws tshem tawm cov hluav taws xob tawg tau zoo yam tsis muaj cov neeg mob ntau ntxiv.
Lwm qhov tseem ceeb tshaj plaws yog daim phiaj zaus, uas sawv cev rau tus naj npawb ntawm cov hlau lead ib nti lossis centimeter.Cov kab hluav taws xob ntau dua ua rau cov hlau lead me me thiab nyias nyias, txhim kho cov duab zoo tab sis nce tus nqi ntawm X-ray daim phiaj.Ib daim phiaj zaus ntawm 103 kab ib nti lossis 40 kab ib centimeter feem ntau yog siv rau kev siv hluav taws xob dav dav.Txawm li cas los xij, cov kab sib chaws siab dua, xws li 178 kab ib nti lossis 70 kab ib xees, raug pom zoo rau cov ntawv tshwj xeeb uas xav tau cov duab zoo dua.
Ntxiv nrog rau daim phiaj sib piv thiab zaus, cov khoom siv kab sib chaws kuj tseem ceeb heev.Ntau yam ntaub ntawv, xws li txhuas, carbon fiber, thiab hybrid daim phiaj, yog siv nyob rau hauv manufacturing X-ray daim phiaj.Aluminium grids yog cov feem ntau siv vim lawv cov nqi-zoo thiab muaj peev xwm nqus tau zoo.Txawm li cas los xij, lawv yuav hnyav dua thiab tuaj yeem ua rau cov duab degradation yog tias tsis ua raws li X-ray beam.Cov pa roj carbon fiber ntau yog lub teeb yuag thiab muaj cov khoom nqus tau zoo, tab sis lawv kim dua.Hybrid daim phiaj sib xyaw ua ke cov txiaj ntsig ntawm ob qho tib si aluminium thiab carbon fiber daim phiaj, muab qhov sib npaug zoo ntawm tus nqi thiab kev ua haujlwm.
Nws tseem yog ib qho tseem ceeb uas yuav tau xav txog cov phiaj xwm focal range, uas yog hais txog qhov sib txawv ntawm X-ray raj-rau-grid nrug nyob rau hauv uas daim phiaj ua tau zoo.Cov tshuab xoo hluav taws xob sib txawv muaj cov kev xav tau sib txawv rau ntau yam focal, thiab xaiv ib daim phiaj uas phim koj lub tshuab specifications yog qhov tseem ceeb.Kev siv kab sib chaws sab nraum qhov pom pom ntau yam tuaj yeem ua rau cov duab zoo tshaj plaws thiab cov neeg mob ntau ntxiv.
Thaum kawg, qhov loj ntawm daim phiaj yuav tsum sib haum mus rau qhov loj ntawm lub tshuab X-ray cov duab kos duab.Siv daim phiaj uas me dhau tuaj yeem ua rau daim phiaj txiav tawm, qhov twg cov npoo ntawm daim phiaj thaiv cov kab hluav taws xob X-ray, ua rau cov duab tsis zoo.Ntawm qhov tod tes, daim phiaj uas loj dhau yuav tsis haum zoo lossis nce tus neeg mob koob tshuaj tsis tsim nyog.
Hauv kev xaus, xaiv txoj caiX-ray daim phiajrau koj lub tshuab X-ray yog qhov tseem ceeb heev kom tau txais cov txiaj ntsig zoo tshaj plaws.Cov yam ntxwv xws li kab sib faib, zaus, cov khoom siv, focal range, thiab loj yuav tsum tau ua tib zoo txiav txim siab los xyuas kom meej qhov ua tau zoo.Kev sab laj nrogX-ray khoomcov tuam txhab lag luam lossis cov kws tshaj lij hluav taws xob tuaj yeem muab cov lus qhia tseem ceeb hauv kev xaiv cov phiaj xwm X-ray tsim nyog rau koj cov kev xav tau tshwj xeeb.
