Medical X-ray tubesyog cov khoom tseem ceeb hauv kev kuaj mob thiab ua lub luag haujlwm tseem ceeb hauv kev tshawb nrhiav thiab kev kuaj mob ntawm ntau yam kab mob. Cov raj no tsim cov X-rays (ib hom hluav taws xob hluav taws xob hluav taws xob) uas nkag mus rau tib neeg lub cev los tsim cov duab ntawm cov qauv sab hauv. Kev siv cov raj xa hluav taws xob kho mob tau hloov pauv txoj hauv kev cov kws kho mob txheeb xyuas thiab saib xyuas ntau yam kab mob.
Nyob rau hauv lub plawv ntawm cov txheej txheem X-ray yog cov kev kho mob X-ray raj, uas muaj ib tug cathode thiab anode. Thaum rhuab, lub cathode emits electrons, uas yog ceev mus rau lub anode, qhov chaw uas lawv sib tsoo thiab tsim X-rays. Cov txiaj ntsig X-ray yog tom qab ntawd coj mus rau tus neeg mob, hla lub cev thiab ntes cov duab ntawm lub tshuab ntes lossis zaj duab xis. Cov txheej txheem no pom cov pob txha, lub cev, thiab cov ntaub so ntswg, ua rau nws yog ib qho cuab yeej tseem ceeb hauv kev kuaj mob.
Ib qho ntawm cov kev siv tseem ceeb ntawm kev kho mob X-ray raj yog kev kuaj xyuas cov pob txha txawv txav. Cov pob txha, dislocations, thiab cov kab mob degenerative xws li mob caj dab tuaj yeem txheeb xyuas tau yooj yim nrog X-ray duab. Qhov pom tseeb ntawm cov pob txha pob txha ua rau cov neeg ua haujlwm kho mob tuaj yeem kuaj xyuas kom raug thiab sau ntawv kho kom tsim nyog. Piv txwv li, nyob rau hauv cov ntaub ntawv ntawm kev raug mob, X-rays tuaj yeem qhia tau sai npaum li cas ntawm qhov raug mob, yog li coj kev cuam tshuam thaum muaj xwm ceev.
Ntxiv nrog rau kev kuaj xyuas pob txha, kev kho mob X-ray hlab pab tshawb xyuas ntau yam kab mob ntawm cov nqaij mos. Cov thev naus laus zis xws li fluoroscopy thiab suav tomography (CT) siv X-ray thev naus laus zis los muab cov duab dynamic thiab ntu ntu ntawm lub cev. Cov kev kuaj pom zoo no tuaj yeem ntsuas cov kabmob sab hauv, cov hlab ntsha, thiab cov qog. Piv txwv li, X-rays hauv siab feem ntau yog siv los kuaj mob ntsws, mob ntsws, thiab lwm yam kab mob ua pa, thaum lub plab X-rays tuaj yeem qhia txog teeb meem xws li plab hnyuv lossis pob zeb hauv lub raum.
Kev kho mob X-ray raj ua ntau tshaj li kev kuaj mob; lawv kuj tseem ceeb heev rau kev saib xyuas cov kab mob thiab kev kho mob kom zoo. Rau cov neeg mob uas tau txais kev kho mob qog noj ntshav, kev kuaj X-ray tsis tu ncua pab ntsuam xyuas qhov ua tau zoo ntawm kev kho mob, tso cai rau kev hloov kho raws sijhawm rau cov phiaj xwm kho mob. Ib yam li ntawd, hauv kev saib xyuas orthopedic, kev soj ntsuam X-ray tuaj yeem ntsuas cov txheej txheem kho mob ntawm pob txha lossis kev ua tiav ntawm kev phais.
Tsis tas li ntawd, kev nce qib hauv X-ray thev naus laus zis tau txhim kho kev ua haujlwm ntawm kev kho mob X-ray raj. Cov tshuab X-ray muaj peev xwm muab cov duab daws teeb meem siab dua thaum txo cov hluav taws xob cuam tshuam, txhim kho cov neeg mob kev nyab xeeb thaum tswj xyuas qhov tseeb. Kev tsim kho tshiab xws li cov tshuab X-ray portable kuj tau nthuav dav cov kev pab cuam duab, tshwj xeeb tshaj yog thaum muaj xwm txheej ceev lossis thaj chaw deb.
Txawm hais tias kev kho mob X-ray raj muaj ntau qhov zoo, lawv cov kev pheej hmoo cuam tshuam yuav tsum raug txiav txim siab, tshwj xeeb tshaj yog raug hluav taws xob. Cov kws kho mob yuav tsum ua raws li "Raws Li Tsawg Raws Li Qhov Tsim Nyog Dose" (ALARA) lub hauv paus ntsiab lus kom txo cov koob tshuaj hluav taws xob tsawg thaum ua kom muaj kev kuaj mob zoo. Qhov no yuav tsum tau ua tib zoo xav txog qhov yuav tsum tau kuaj X-ray thiab siv cov kev tiv thaiv tsim nyog rau cov neeg mob thiab cov neeg ua haujlwm.
Hauv cov ntsiab lus,kho mob X-ray tubesua lub luag haujlwm tseem ceeb hauv kev tshawb nrhiav thiab tswj kab mob. Lawv daim ntawv thov yog dav, npog ntau yam mob los ntawm cov pob txha raug mob mus rau cov nqaij mos txawv txav. Raws li kev siv thev naus laus zis txuas ntxiv mus, X-ray imaging peev xwm yuav ntxiv txhim kho qhov tseeb ntawm kev kuaj mob thiab kev saib xyuas neeg mob. Kev koom ua ke txuas ntxiv ntawm cov raj xa hluav taws xob kho mob rau hauv kev kho mob qhia txog lawv qhov tseem ceeb hauv cov tshuaj niaj hnub, thaum kawg pab txhim kho kev noj qab haus huv ntawm cov neeg mob thoob ntiaj teb.
