X-ray thev naus laus zis tau hloov kho cov tshuaj niaj hnub no, dhau los ua cov cuab yeej tseem ceeb rau kev kuaj mob thiab kho ntau yam kab mob.Hauv plawv ntawm X-ray technology yog ib qhoX-ray tube, ib qho khoom siv uas tsim hluav taws xob hluav taws xob, uas yog siv los tsim cov duab ntawm cov qauv sab hauv ntawm tib neeg lub cev.
An X-ray tubemuaj cov cathode, anode thiab lub tshuab nqus tsev vacuum.Lub cathode yog tsis zoo them thiab feem ntau yog ua los ntawm tungsten, thaum lub anode yog zoo them thiab feem ntau yog ua los ntawm tooj liab los yog tungsten.Thaum lub cathode yog rhuab mus rau ib tug kub kub, electrons yog emissions thiab ceev mus rau lub anode, qhov twg lawv tsoo nrog lub hom phiaj cov khoom.Qhov kev sib tsoo no ua rau X-ray photons uas taug kev los ntawm lub tshuab nqus tsev thiab mus rau hauv cov khoom raug kuaj.
Ib qho tseem ceeb ntawm X-ray raj yog lub peev xwm ntawm lub anode kom dissipate lub tshav kub uas tsim los ntawm electrons sib tsoo nrog lub hom phiaj.Anodes feem ntau muaj kev sib hloov disk teeb tsa tsim los ua kom cov cua sov kom zoo thaum tswj xyuas cov txheej txheem kev ncaj ncees ntawm cov cuab yeej.Raws li thev naus laus zis thev naus laus zis thev naus laus zis, cov raj tshiab tuaj yeem tsim cov duab zoo dua thaum xav tau kev saib xyuas tsawg dua thiab lub neej ntev dua.
Lwm qhov tseem ceeb ntawm X-ray thev naus laus zis yog kev tswj hwm hluav taws xob.Vim tias qhov raug hluav taws xob ntau tuaj yeem ua rau muaj kev phom sij rau tib neeg lub cev, cov raj X-ray niaj hnub no tau tsim los txo cov hluav taws xob tsawg.Piv txwv li, qee lub raj X-ray muaj qhov tsis siv neeg kis tau los ntawm kev hloov pauv hluav taws xob los ntawm cov khoom xws li lub cev loj thiab cov ntaub so ntswg.Qhov no ua rau cov duab meej meej dua thiab raug hluav taws xob tsawg dua.
Thaum kawg, niaj hnubX-ray tubesmuaj ntau yam ntxiv nta uas txhim khu kev ua tau zoo thiab siv tau.Piv txwv li, qee lub raj muaj qhov ua kom pom tseeb, tso cai rau cov neeg siv los kho qhov loj thiab cov duab ntawm X-ray beam kom haum rau lawv cov kev xav tau tshwj xeeb.Lwm cov raj tau nruab nrog lub tshuab txias txias rau kev siv txuas ntxiv, txo qis qis qis thiab ua kom muaj txiaj ntsig zoo.
Hauv kev xaus, X-ray raj tshuab tau los ntev heev txij li thaum nws pib thiab txuas ntxiv mus rau niaj hnub no.Los ntawm kev txhim kho hauv anode thev naus laus zis, kev tswj hluav taws xob tiv thaiv hluav taws xob, thiab lwm yam muaj peev xwm, niaj hnubX-ray tubesyog ib qho kev ua tau zoo ntawm engineering uas tau ua rau suav tsis txheeb cov kws kho mob los kuaj xyuas thiab kho ntau yam kab mob.Raws li kev siv thev naus laus zis txuas ntxiv mus, nws yog qhov zoo siab los xav txog qhov kev nce qib tshiab hauv X-ray tube thev naus laus zis yuav tso cai rau peb ua tiav yav tom ntej.
