Cov tshuab X-rayua lub luag haujlwm tseem ceeb hauv kev kho mob niaj hnub no, pab kuaj mob thiab kho ntau yam kab mob. Hauv plawv ntawm cov tshuab no yog ib qho tseem ceeb hu ua lub raj X-ray, uas tsim cov X-rays uas xav tau los ntes cov duab ntxaws ntxaws ntawm lub cev tib neeg. Kev siv tshuab raj X-ray tau ua tiav ntau yam hauv xyoo tas los no, tshwj xeeb tshaj yog rau kev suav tomography (CT). Cov blog no lub hom phiaj yog los tshawb nrhiav cov kev txhim kho no thiab lawv cov kev cuam tshuam rau thaj chaw.
Kawm txog cov raj xa duab X-ray:
An Lub raj xa duab xoo hluav taws xobyog ib lub cuab yeej kaw uas kaw los ntawm lub tshuab nqus tsev uas hloov lub zog hluav taws xob mus ua hluav taws xob X-ray. Ib qho kev tshawb pom tseem ceeb hauv kev siv tshuab raj X-ray yog kev qhia txog cov anodes tig. Qhov kev tsim kho tshiab no ua rau muaj zog ntau dua thiab lub sijhawm luam theej duab sai dua, ua rau CT scans ua haujlwm tau zoo dua thiab raug dua. Tsis tas li ntawd, cov raj niaj hnub siv tungsten ua cov khoom siv vim nws muaj tus lej atomic siab, ua rau muaj peev xwm tsim cov duab X-ray zoo.
Kev kuaj CT thiab vim li cas nws thiaj tseem ceeb:
Kev thaij duab CT yog ib txoj kev siv tshuab thaij duab kho mob uas tsis yog kev phais uas muab cov duab txiav ntawm lub cev kom ntxaws. Cov duab no qhia txog cov qauv sab hauv uas nyuaj, pab cov kws kho mob kuaj mob thiab kho cov mob kom raug. Kev thaij duab CT feem ntau siv los soj ntsuam cov cheeb tsam xws li lub hlwb, hauv siab, plab thiab lub duav. Kev nce qib hauv thev naus laus zis X-ray tau ua rau kev ua haujlwm zoo thiab kev nyab xeeb ntawm kev thaij duab CT zoo dua qub.
Kev daws teeb meem ntawm daim duab zoo dua:
Ib qho kev vam meej loj yog kev tsim cov raj X-ray uas muaj cov qhov me me. Qhov tsom yog ib qho tseem ceeb hauv kev txiav txim siab qhov kev daws teeb meem ntawm cov duab tshwm sim. Qhov tsom me dua ua rau cov duab ntse thiab meej dua, ua rau muaj kev kuaj mob tau zoo dua. Qhov kev txhim kho no yog qhov tshwj xeeb tshaj yog rau kev kuaj pom cov teeb meem me me thiab cov qhov txhab uas cov raj X-ray tiam dhau los tej zaum yuav tsis pom.
Txo cov tshuaj tua kab mob:
Lwm qhov teeb meem tseem ceeb hauv kev thaij duab kho mob yog kev raug hluav taws xob. Txhawm rau daws qhov teeb meem no, cov chaw tsim khoom tau siv cov thev naus laus zis tsim los txo cov tshuaj tua kab mob thaum lub sijhawm CT scans. Lub raj X-ray tiv taus cua sov ntau dua, ua ke nrog cov txheej txheem txias siab heev, ua rau cov txheej txheem scan ntev dua yam tsis muaj kev cuam tshuam rau kev nyab xeeb ntawm tus neeg mob. Los ntawm kev ua kom zoo dua ntawm kev tsim X-ray, cov kev nce qib no ua tiav txo cov tshuaj tua kab mob thaum tseem tswj tau qhov zoo ntawm daim duab.
Kev ceev thiab kev ua tau zoo dua:
Thaum thev naus laus zis nce qib, qhov xav tau kev luam theej duab sai dua thiab ua haujlwm tau zoo dua kuj tseem ceeb heev. Cov chaw tsim khoom tau teb rau qhov xav tau no los ntawm kev tsim cov raj X-ray uas muaj peev xwm tsim cov raj xa dej siab dua, yog li ua rau kev luam theej duab ceev dua. Qhov kev txhim kho no yog qhov tseem ceeb hauv cov xwm txheej ceev uas lub sijhawm yog qhov tseem ceeb, uas tso cai rau cov kws kho mob kom sai sai soj ntsuam cov kev raug mob lossis cov mob hnyav.
xaus lus:
Kev nce qib hauvLub raj xa duab xoo hluav taws xobthev naus laus zis tau hloov pauv txoj kev tshawb fawb txog kev siv CT scanning, muab kev daws teeb meem duab siab dua, txo cov tshuaj tua kab mob thiab ceev dua rau cov kws kho mob. Cov kev txhim kho no tau txhim kho qhov tseeb thiab kev ua haujlwm ntawm kev kuaj mob thiab kev kho mob. Thaum thev naus laus zis txuas ntxiv hloov zuj zus, peb tuaj yeem cia siab tias yuav muaj kev tsim kho tshiab ntxiv hauv thev naus laus zis X-ray tube, qhib lub qhov rooj rau cov txheej txheem thaij duab kho mob kom meej dua thiab tsis tshua muaj kev cuam tshuam. Nrog txhua kauj ruam mus tom ntej, yav tom ntej ntawm kev siv hluav taws xob yuav ci dua, ua rau muaj kev noj qab haus huv tag kis rau txhua tus.
