CT scanner (ua piv txwv Tom qab scanner) yog cov kev ua haujlwm kho mob uas sib xyaw ua ke nrog kev ua computer los tsim cov ncauj lus kom ntxaws ntawm lub cev. Thaum cov neeg mob tau dhau CT Scanner cov txheej txheem, lawv feem ntau tau qhia kom tuav lawv cov pa ntawm lub sijhawm tshwj xeeb. Qhov uas yuav tsum muaj no yuav zoo li yooj yim, tab sis nws plays lub luag haujlwm tseem ceeb hauv kev ua kom lub CT scanner ua cov duab kev kuaj mob zoo. Hauv cov kev qhia no, peb yuav tshawb txog kev ua pa yog qhov tseem ceeb yog lub sijhawm CT scanner kev kuaj xyuas thiab nws cuam tshuam li cas rau cov txheej txheem kev kuaj mob.
Yuav npaj li cas rau CT scan
Npaj rau a CT scanner tshuaj ntsuam muaj feem muaj ntau cov kauj ruam tseem ceeb uas cuam tshuam qhov zoo ntawm cov duab zoo. Niaj hnub nimno CT scanner thev naus laus zis tau dhau los, tsis tau muaj tus mob kev sib koom tes tseem ceeb hauv kev nrhiav tau cov txiaj ntsig zoo.
Thaum tau teem sijhawm rau cov txheej txheem ct scanner cov txheej txheem, cov neeg mob feem ntau tau txais cov lus qhia tshwj xeeb raws li kev xeem. Rau lub plab lossis hauv siab CT scanner kev yees duab, yoo mov rau ob peb teev ua ntej yuav tsim nyog. Qhov kev npaj ua no pab tau CT scanner ntes cov duab ntshiab ntawm cov kabmob sab hauv yam tsis muaj kev cuam tshuam los ntawm cov txheej txheem digestive.
Lub CT Scanner Technologist yuav qhia cov txheej txheem hauv kev nthuav dav ua ntej pib. Lawv mam li hais txog qhov tseem ceeb ntawm cov tseem tshuav thiab ua pa cov lus qhia meej. Lub CT scanner tshuab nws tus kheej yog qhov loj, donut-puab cov cuab yeej nrog lub rooj txav mus los ntawm lub chaw. Raws li CT scanner roundates ib ncig ntawm lub cev, nws yuav ntau pua cov duab uas siv lub computer mam li muab cov ntsiab lus tsim cov ncauj lus kom ntxaws hla kev.
Qhov chaw kom zoo yog qhov tseem ceeb rau kev ntsuas qhov ua tau CT scanner. Tus thev naus laus zis yuav pab koj dag hauv txoj haujlwm tseeb, feem ntau siv hauv ncoo lossis cov hlua khi kom muaj kev ruaj khov. Txoj haujlwm no tau ua kom muaj cov scanner ct tuaj yeem ntes cov qauv tsim nyog rau cov txheej txheem qub nrog cov kev tawm tsam tsawg kawg nkaus.
Ntawm no yog ib daim ntawv teev kev npaj phiaj xwm rau CT Scanner Tus Txheej Txheem:
Ua raws li cov lus qhia yoo mov los ntawm koj tus kws kho mob
Hnav xis, xoob-haum khaub ncaws tsis muaj hlau zippers lossis khawm
Tshem cov hniav nyiaj hniav kub, tsom iav, thiab cov khoom hlau uas tuaj yeem cuam tshuam nrog CT scanner
Qhia technologist txog cov tshuaj koj noj
Sib tham txog qhov uas cev xeeb tub nrog koj tus kws kho mob ua ntej CT scanner kev tshuaj ntsuam
Tuaj kom ntxov ua kom tiav cov ntaub ntawv thiab daws cov kev txhawj xeeb
Lub CT Scanner tus txheej txheem nws tus kheej feem ntau tsis mob, txawm hais tias qee tus neeg mob yuav muaj kev tsis xis nyob los ntawm kev dag. Lub CT scanner tshuab ua rau whirring thiab nyem suab nrov thaum lub sijhawm ua haujlwm, uas yog ib txwm ua tiav.
To taub cov txheej txheem scanner tuaj yeem pab zam kev ntxhov siab ntxhov siab. Lub CT Scanner Technologist ua haujlwm ua lub tshuab los ntawm chav tsev nyob ib sab tab sis tuaj yeem pom, hnov, thiab hais lus rau koj kom koj kuaj. Qhov kev sib txuas lus no tso cai rau tus thev naus laus zis los muab cov lus qhia txog kev ua pa ntawm lub sijhawm CT Scanner txheej txheem.
Thaum siv cov neeg sawv cev sib txuas
Ntau tus CT Scanner kev soj ntsuam siv cov neeg sawv cev sib piv rau cov duab zoo thiab muab cov ntaub ntawv kuaj mob kuaj mob. Cov ntaub ntawv sib xws, feem ntau iodine-based, pab qhia cov ntaub so ntswg tshwj xeeb, lossis cov hlab ntsha lossis cov kabmob hauv lub scanner duab.
Thaum muaj cov txheej txheem ct scanner yuav tsum tau saib xyuas cov neeg saib xyuas, cov neeg mob yuav tau txais tus neeg sawv cev los ntawm cov kab uas tsis muaj peev xwm los ntawm ib qho chaw, thiab ib qho, nyob ntawm thaj chaw uas tau kuaj xyuas. Tus neeg saib xyuas kev sib piv nrog los ntawm lub cev thiab hloov pauv ib ntus kom cov ntaub so ntswg tshwm sim ntawm CT scanner cov duab.
Lub sij hawm ua pa-tuav tau tshwj xeeb tshaj yog thaum cov neeg sawv cev sib txawv yog siv nrog CT Scanner. Raws li cov khoom sib piv ntws los ntawm cov hlab ntshav, ct scanner yuav tsum ntes cov duab ntawm lub sij hawm qhia meej. Tuav koj ua tsis taus pa thaum lub sijhawm tseem ceeb tshaj plaws los tiv thaiv cov khoom cuav uas tuaj yeem ua rau cov qauv sib txawv.

Niaj hnub nimno CT scanner technology suav nrog Bolus nrhiav cov software uas saib xyuas txog qhov sib piv hauv lub sijhawm tiag tiag. Qhov no txawj ntse CT scanner feature tso cai rau technologist pib pib kuaj pom meej thaum lub hom phiaj, maximizing kev kuaj mob thaum muaj kev cuam tshuam hluav taws xob tsawg tsawg.
Cov neeg mob raug txhim kho CT Scanner Cov txheej txheem yuav tsum paub txog cov kev mob tshwm sim, uas feem ntau me thiab ib ntus. Cov no yuav suav nrog:
Lub CT scanner Technologist yuav saib xyuas koj kom ze thaum thiab tom qab kev tswj hwm kev sib raug zoo. Yog tias koj ntsib cov tsos mob txawv txawv thaum lub sij hawm CT Scanner cov txheej txheem, koj yuav tsum tau qhia tam sim kws kho technologist.
Rau qee qhov kev kuaj ntsuas scanner, tshwj xeeb cov ntsuas ntawm lub hauv siab lossis lub plab, tus neeg sawv cev sib piv tuaj yeem ua pa ib ntus. Qhov kev hnov no ua rau cov pa ua kom haum rau kev ua pa ntau ntxiv rau ntau qhov kev txav mus los hauv theem no tuaj yeem cuam tshuam rau cov duab ct cant CT scanner daim duab zoo.
Qhov zoo ntawm cov lus qhia ua tsis taus pa
Ua kom muaj kev ua pa kom cov lus qhia thaum a CT scanner tshuaj ntsuam muaj muaj cov txiaj ntsig ntau uas cuam tshuam kev kuaj mob thiab cov neeg mob tu. Nkag siab txog cov kev zoo no tuaj yeem pab cov neeg mob txaus siab rau qhov tseem ceeb ntawm qhov yooj yim tseem ceeb.
Thawj qhov txiaj ntsig ntawm kev ua pa kom zoo-tuav thaum lub sij hawm CT Scanner cov txheej txheem yog kev tshem tawm cov lus cuav. Thaum tus neeg mob ua pa thaum kuaj cov duab, lub txiaj ntsig ct scanner cov duab yuav qhia qhov muag plooj lossis nqaij ntuag cov ntsiab lus tseem ceeb. Cov khoom cuav no tuaj yeem ua rau:
