Cov raj xa duab X-rayyog cov cuab yeej tseem ceeb uas siv rau hauv ntau qhov chaw kho mob thiab kev lag luam. Kev paub txog cov hauv paus ntawm nws ua haujlwm li cas, nrog rau nws cov txiaj ntsig thiab qhov tsis zoo, yog qhov tseem ceeb thaum txiav txim siab seb cov thev naus laus zis no puas yog rau koj.
Hauv lub plawv ntawm ib qhoLub raj xa duab xoo hluav taws xobyog ob lub ntsiab lus tseem ceeb: qhov chaw ntawm cov hluav taws xob (lub cathode) thiab lub hom phiaj uas nqus cov hluav taws xob ntawd (lub anode). Thaum hluav taws xob hla dhau lub cuab yeej, nws ua rau lub cathode tso tawm lub zog hauv daim ntawv ntawm X-rays. Cov X-rays no ces dhau los ntawm cov ntaub so ntswg lossis khoom thiab nqus los ntawm lub anode, tsim ib daim duab lossis daim duab ntawm zaj duab xis.
Ib qho txiaj ntsig loj ntawm kev siv X-rays dua li lwm cov txheej txheem thaij duab yog tias lawv tuaj yeem nkag mus rau hauv cov khoom tuab yam tsis muaj kev cuam tshuam dua li lwm hom kev thaij duab, xws li ultrasound lossis magnetic resonance imaging (MRI). Qhov no ua rau lawv zoo tagnrho rau kev saib cov khoom tuab, xws li pob txha lossis cov hlau, hauv cov txheej txheem kho mob qhov twg qhov tseeb yog qhov tseem ceeb. Tsis tas li ntawd, lawv pheej yig dua piv rau MRI scanners thiab lwm yam khoom siv thaij duab, ua rau lawv pheej yig rau cov neeg siv ua lag luam thiab hauv tsev.
Txawm li cas los xij, qhov tsis zoo yog tias cov duab X-ray tsim cov hluav taws xob, uas tuaj yeem ua rau muaj kev phom sij yog tias tsis siv kom raug; yog li ntawd, yuav tsum ua raws li cov txheej txheem kev nyab xeeb nruj thaum siv cov txheej txheem no. Tsis tas li ntawd, vim lawv lub zog nkag mus, lawv yuav tsis muab cov duab ntxaws ntxaws tshwj tsis yog tias tau teeb tsa tshwj xeeb rau ib qho kev siv tshwj xeeb - yog li ntawd cov txheej txheem scanning siab dua xws li MRI qee zaum nyiam dua li cov tshuab X-ray ib txwm muaj.
Hauv kev xaus lus, txawm hais tias muaj qee qhov tsis zoo ntawm kev siv cov raj X-ray nyob ntawm koj daim ntawv thov, lawv tseem yuav tsim nyog xav txog vim lawv pheej yig thiab muaj peev xwm muab cov txiaj ntsig tseeb sai thaum lawv xav tau tshaj plaws. Txawm hais tias koj tab tom nrhiav txoj hauv kev tshiab los kuaj mob sai sai hauv tsev lossis xav siv nws hauv koj qhov chaw ua lag luam - kev nkag siab txog cov khoom siv no ua haujlwm li cas tuaj yeem pab ua kom koj tau txais yam koj xav tau ntawm lawv!
