Cov raj xa hluav taws xob kho mobyog cov khoom tseem ceeb hauv kev kuaj mob thiab ua lub luag haujlwm tseem ceeb hauv kev kuaj mob thiab kuaj mob ntau yam kab mob. Cov raj no tsim cov duab X-ray (ib hom hluav taws xob hluav taws xob) uas nkag mus rau hauv tib neeg lub cev los tsim cov duab ntawm cov qauv sab hauv. Kev siv cov raj X-ray kho mob tau hloov pauv txoj hauv kev uas cov kws kho mob txheeb xyuas thiab saib xyuas ntau yam kab mob.
Lub plawv ntawm cov txheej txheem thaij duab X-ray yog lub raj xa duab X-ray kho mob, uas muaj ib lub cathode thiab ib lub anode. Thaum cua sov, lub cathode tso tawm cov electrons, uas raug nrawm mus rau lub anode, qhov chaw uas lawv sib tsoo thiab tsim cov duab X-rays. Cov duab X-rays uas tau txais tom qab ntawd raug coj mus rau tus neeg mob, hla dhau lub cev thiab ntes cov duab ntawm lub tshuab ntes lossis zaj duab xis. Cov txheej txheem no pom cov pob txha, cov kabmob, thiab cov nqaij, ua rau nws yog ib qho cuab yeej tseem ceeb hauv kev kuaj mob.
Ib qho ntawm cov kev siv tseem ceeb ntawm cov raj X-ray kho mob yog kev kuaj pom cov pob txha tsis zoo. Cov pob txha tawg, cov pob txha tawg, thiab cov kab mob tsis zoo xws li mob pob qij txha tuaj yeem txheeb xyuas tau yooj yim nrog kev thaij duab X-ray. Qhov pom tseeb ntawm cov qauv pob txha ua rau cov neeg ua haujlwm kho mob tuaj yeem kuaj mob tau zoo thiab sau ntawv kho mob kom raug. Piv txwv li, thaum muaj kev raug mob, X-rays tuaj yeem qhia tau sai sai qhov loj ntawm qhov raug mob, yog li coj kev pabcuam thaum muaj xwm txheej ceev.
Ntxiv rau kev thaij duab pob txha, cov raj X-ray kho mob pab nrhiav ntau yam kab mob ntawm cov nqaij mos. Cov thev naus laus zis xws li fluoroscopy thiab computed tomography (CT) siv thev naus laus zis X-ray los muab cov duab dynamic thiab cross-sectional ntawm lub cev. Cov qauv duab siab heev no tuaj yeem soj ntsuam cov kab mob sab hauv, cov hlab ntsha, thiab cov qog nqaij hlav. Piv txwv li, cov duab X-ray hauv siab feem ntau siv los nrhiav mob ntsws, mob qog nqaij hlav hauv ntsws, thiab lwm yam kab mob ua pa, thaum cov duab X-ray hauv plab tuaj yeem qhia txog teeb meem xws li kev thaiv txoj hnyuv lossis pob zeb hauv lub raum.
Cov raj X-ray kho mob ua ntau tshaj li kev kuaj mob xwb; lawv kuj tseem ceeb heev rau kev saib xyuas kev loj hlob ntawm tus kab mob thiab kev kho mob zoo. Rau cov neeg mob uas tab tom kho mob qog noj ntshav, kev thaij duab X-ray tsis tu ncua pab ntsuas qhov ua tau zoo ntawm kev kho mob, ua rau muaj kev hloov kho raws sijhawm rau cov phiaj xwm kho mob. Ib yam li ntawd, hauv kev kho mob pob txha, kev thaij duab X-ray tom qab tuaj yeem ntsuas qhov kev kho mob ntawm cov pob txha tawg lossis kev vam meej ntawm kev phais mob.
Ntxiv mus, kev nce qib hauv thev naus laus zis X-ray tau txhim kho kev ua haujlwm ntawm cov raj X-ray kho mob. Cov tshuab X-ray digital muaj peev xwm muab cov duab daws teeb meem siab dua thaum txo qis kev raug hluav taws xob, txhim kho kev nyab xeeb ntawm tus neeg mob thaum tswj hwm qhov tseeb ntawm kev kuaj mob. Kev tsim kho tshiab xws li cov tshuab X-ray nqa tau kuj tau nthuav dav kev pabcuam duab, tshwj xeeb tshaj yog thaum muaj xwm txheej ceev lossis thaj chaw nyob deb.
Txawm hais tias cov raj xa duab X-ray kho mob muaj ntau yam zoo, tab sis yuav tsum xav txog lawv cov kev pheej hmoo, tshwj xeeb tshaj yog kev raug hluav taws xob. Cov kws kho mob yuav tsum ua raws li txoj cai "As Low As Reasonable Dose" (ALARA) kom txo qhov koob tshuaj hluav taws xob thaum ua kom ntseeg tau tias muaj kev kuaj mob zoo. Qhov no yuav tsum tau xav txog qhov xav tau kev kuaj duab X-ray thiab ua cov kev tiv thaiv tsim nyog rau cov neeg mob thiab cov neeg ua haujlwm.
Hauv kev xaus,cov raj xa hluav taws xob kho mobua lub luag haujlwm tseem ceeb hauv kev kuaj mob thiab tswj kab mob. Lawv cov kev siv dav dav, npog ntau yam mob los ntawm kev raug mob pob txha mus rau qhov tsis zoo ntawm cov nqaij mos. Thaum thev naus laus zis txuas ntxiv mus, cov peev xwm thaij duab X-ray yuav txhim kho qhov tseeb ntawm kev kuaj mob thiab kev saib xyuas tus neeg mob. Kev koom ua ke ntawm cov raj X-ray kho mob rau hauv kev kho mob qhia txog lawv qhov tseem ceeb hauv kev kho mob niaj hnub no, thaum kawg pab txhim kho kev noj qab haus huv ntawm cov neeg mob thoob plaws ntiaj teb.
