Hauv kev siv tshuab thaij duab kho mob, cov raj X-ray thiab cov tshuab CT scanners yog ob lub thev naus laus zis tseem ceeb uas tau hloov pauv txoj kev kuaj mob. Txawm hais tias ob lub cuab yeej siv X-rays los saib cov qauv sab hauv ntawm tib neeg lub cev, lawv ua haujlwm sib txawv thiab muaj kev siv sib txawv. Kev nkag siab txog qhov sib txawv ntawm cov raj X-ray thiab cov tshuab CT scanners yog qhov tseem ceeb rau cov neeg ua haujlwm kho mob thiab cov neeg mob vim nws cuam tshuam rau lawv xaiv cov thev naus laus zis thaij duab tsim nyog rau lawv cov kev xav tau kho mob.
Cov raj xa hluav taws xob X-Ray: Cov ntsiab lus tseem ceeb
An Lub raj xa duab xoo hluav taws xobyog ib lub cuab yeej uas tsim cov duab X-ray los ntawm kev ua kom cov electrons nrawm thiab coj lawv mus rau ib yam khoom siv, feem ntau yog ua los ntawm tungsten. Thaum cov electrons muaj zog no sib tsoo nrog lub hom phiaj, lawv tsim cov duab X-ray uas tuaj yeem nkag mus rau hauv lub cev thiab tsim ib daim duab ntawm zaj duab xis lossis lub tshuab ntes digital. Kev thaij duab X-ray ib txwm muaj feem ntau yog siv los tshuaj xyuas cov pob txha, nrhiav pom cov pob txha tawg, thiab kuaj mob xws li mob ntsws lossis mob qog hauv siab.
Qhov zoo tshaj plaws ntawm cov raj X-ray yog lawv qhov ceev thiab ua haujlwm tau zoo. Kev kuaj mob X-ray ib txwm siv sijhawm ob peb feeb xwb, ua rau nws zoo tagnrho rau cov xwm txheej ceev. Tsis tas li ntawd, cov tshuab X-ray feem ntau yooj yim nrhiav tau thiab pheej yig dua li cov tshuab CT scanners, ua rau lawv yog cov cuab yeej siv tau zoo tshaj plaws hauv ntau lub tsev kho mob.
CT scanners: ib kauj ruam ntxiv
Cov tshuab computer tomography (CT) scanners, ntawm qhov tod tes, tau coj cov thev naus laus zis duab mus rau qib tshiab. Cov tshuab CT scanners siv lub raj X-ray tig los ntes ntau daim duab los ntawm ntau lub kaum sab xis ntawm lub cev. Cov duab no tom qab ntawd raug ua los ntawm lub khoos phis tawj los tsim cov ntu ntawm lub cev, muab cov duab ntxaws ntxaws ntxiv ntawm cov qauv sab hauv dua li cov duab X-ray ib txwm muaj.
Cov ntaub ntawv ntxaws ntxiv uas muab los ntawm CT scans yog qhov tshwj xeeb tshaj yog rau kev kuaj mob cov mob nyuaj, xws li kev raug mob sab hauv, mob qog noj ntshav, thiab cov kab mob cuam tshuam rau cov nqaij mos. CT scans tuaj yeem qhia cov ntaub ntawv hais txog cov kabmob, cov hlab ntsha, thiab txawm tias cov qog nqaij hlav uas tej zaum yuav tsis pom ntawm cov duab X-ray ib txwm muaj. Txawm li cas los xij, qhov kev nce ntxiv ntawm cov ntaub ntawv ntxaws ntxiv no tuaj yeem ua rau muaj nqi; CT scans feem ntau cuam tshuam nrog kev raug hluav taws xob ntau dua li cov duab X-ray ib txwm muaj.
Qhov sib txawv tseem ceeb hauv kev thaij duab
Qhov zoo ntawm daim duab thiab cov ntsiab lusIb qho ntawm qhov sib txawv tseem ceeb tshaj plaws ntawm cov raj X-ray thiab cov tshuab luam theej CT yog qib ntawm cov ntsiab lus hauv cov duab uas lawv tsim tawm. Cov duab X-ray muab qhov pom ob-seem, thaum cov tshuab luam theej CT muab cov duab peb-seem uas tuaj yeem rov tsim dua rau hauv ntau lub dav hlau sib txawv, uas ua rau muaj kev ntsuam xyuas ntau dua ntawm thaj chaw uas lawv xav tau.
Kev raug hluav taws xobRaws li tau hais ua ntej lawm, CT scans feem ntau ua rau cov neeg mob raug cov hluav taws xob ntau dua li cov X-rays ib txwm muaj. Qhov no tseem ceeb heev thaum xav txog cov kev pheej hmoo thiab cov txiaj ntsig ntawm txhua txoj kev thaij duab, tshwj xeeb tshaj yog rau cov pej xeem tsis muaj zog xws li cov menyuam yaus lossis cov neeg mob uas xav tau ntau daim scans.
Cov cim qhia rau kev sivFeem ntau, cov raj xa duab X-ray siv rau kev ntsuam xyuas yooj yim xws li kuaj xyuas seb puas muaj pob txha tawg lossis muaj kab mob. Qhov sib txawv, cov tshuab CT scanners zoo dua rau cov teeb meem kuaj mob nyuaj dua, xws li ntsuas qhov mob plab, nrhiav pom cov qog nqaij hlav, lossis npaj phais.
Tus nqi thiab kev nkag tau yooj yimFeem ntau cov tshuab X-ray pheej yig dua thiab muaj ntau hauv ntau qhov chaw kho mob, suav nrog cov chav kho mob sab nraud thiab chav kho mob thaum muaj xwm txheej ceev. Cov tshuab CT scanners, thaum muab cov duab zoo dua, kim dua thiab tej zaum yuav tsis muaj nyob hauv txhua qhov chaw kho mob.
xaus lus
Hauv kev xaus, ob qho tib siCov raj xa duab X-raythiab CT scanners ua lub luag haujlwm tseem ceeb hauv kev thaij duab kho mob, thiab txhua tus muaj nws tus kheej qhov zoo thiab qhov txwv. Kev nkag siab txog qhov sib txawv ntawm ob lub thev naus laus zis no tuaj yeem pab cov kws kho mob txiav txim siab txog qhov kev thaij duab twg zoo tshaj plaws rau lawv cov neeg mob. Thaum thev naus laus zis txuas ntxiv mus, kev koom ua ke ntawm X-ray thiab CT imaging yuav txuas ntxiv mus, txhim kho kev muaj peev xwm kuaj mob thiab kev saib xyuas tus neeg mob.
