Cov raj xa duab X-ray hniavyog cov cuab yeej tseem ceeb hauv kev kho hniav niaj hnub no, ua rau cov kws kho hniav tuaj yeem kuaj mob thiab kho ntau yam mob hniav tau zoo. Ntawm ntau hom raj X-ray, cov uas tau ntawv pov thawj los ntawm Equipment Inspection (CEI) sawv tawm rau lawv qhov kev ntseeg tau thiab qhov tseeb. Tsab xov xwm no yuav tshawb nrhiav tsib yam tseem ceeb ntawm raj X-ray thiab qhia txog lawv cov haujlwm hauv raj X-ray hniav.
1. Cathode
Lub cathode yog ib qho ntawm cov khoom tseem ceeb ntawm lub raj xa duab X-ray (xws li cov raj xa duab X-ray hniav). Nws muaj ib lub filament thiab ib lub khob tsom. Lub filament tsim cov electrons los ntawm kev tso tawm thermionic thaum cua sov. Hauv cov raj xa duab X-ray hniav, lub cathode yog tsim los tsim cov kwj deg tswj hwm ntawm cov electrons thiab coj nws mus rau lub anode. Lub khob tsom pab kom cov electrons no sib sau ua ke rau hauv ib lub beam nqaim, uas yog qhov tseem ceeb rau kev tsim cov duab zoo ntawm cov qauv hniav.
In Cov raj xa hluav taws xob X-ray uas tau ntawv pov thawj los ntawm CEI, lub cathode tau tsim thiab sim ua haujlwm zoo kom ntseeg tau tias muaj kev ua haujlwm zoo tshaj plaws. Daim ntawv pov thawj no lav tias lub cathode tuaj yeem tsim tau lub teeb hluav taws xob ruaj khov thiab txhim khu kev qha, uas yog qhov tseem ceeb rau kev thaij duab tseeb.
2. Anode
Lub anode, nyob rau sab nraud ntawm lub cathode, ua lub luag haujlwm tseem ceeb hauv kev tsim cov duab X-ray. Thaum cov electrons tawm ntawm lub cathode sib tsoo nrog lub anode, lawv qeeb qeeb sai, yog li tsim cov duab X-rays. Lub anode feem ntau yog ua los ntawm cov khoom siv atomic number siab, xws li tungsten, uas ua haujlwm tau zoo heev ntawm kev tsim cov duab X-rays.
Hauv cov raj xa duab X-ray hniav, lub anode feem ntau yog tsim los kom tig tau, uas pab tshem tawm cov cua sov uas tsim tawm thaum lub sijhawm tsim duab X-ray. Qhov no yog qhov tseem ceeb tshwj xeeb rau cov raj xa duab X-ray hniav uas tau ntawv pov thawj los ntawm CEI, vim nws ua rau lub neej ntev dua thiab kev ntseeg tau ntawm lub cuab yeej zoo dua. Lub anode uas ua haujlwm zoo ua kom cov kws kho hniav tau txais cov duab zoo yam tsis txhawj txog kev kub dhau lossis cov khoom siv tsis ua haujlwm zoo.
3. Lub thawv iav
Lub thawv iav yog ib qho tseem ceeb ntawm lub raj X-ray, uas muaj ob qho tib si cathode thiab anode. Nws tsim los tsim kom muaj qhov chaw nqus tsev, uas tseem ceeb rau kev tsim cov duab X-ray zoo. Qhov tsis muaj cua hauv lub thawv tiv thaiv kev tawg ntawm cov hluav taws xob, ua rau muaj lub teeb X-ray uas tsom mus rau ntau dua.
Lub thawv iav ntawm cov raj X-ray hniav yog tsim tshwj xeeb los tiv taus qhov kub thiab txias siab. Daim ntawv pov thawj CEI ua kom lub thawv iav ua tau raws li cov qauv kev nyab xeeb thiab kev ua tau zoo, ua rau cov kws kho hniav ntseeg siab rau qhov kev ua haujlwm ntawm lawv cov khoom siv X-ray. Lub thawv iav zoo ua rau kev ua haujlwm zoo dua thiab kev ua haujlwm ntawm kev thaij duab X-ray hniav.
4. Kev lim dej
Kev lim dej yog ib qho tseem ceeb ntawm cov raj X-ray (xws li cov raj X-ray hniav) vim nws pab txhim kho qhov zoo ntawm lub teeb X-ray. Kev lim dej suav nrog kev siv cov ntaub ntawv uas tuaj yeem nqus cov duab X-rays uas muaj zog tsawg, uas tsis yog tsuas yog tsis pab txhawb rau qhov zoo ntawm daim duab xwb tab sis kuj ua rau tus neeg mob raug hluav taws xob ntau dua. Los ntawm kev tshem tawm cov duab X-rays uas tsis xav tau no, kev lim dej tuaj yeem txhim kho qhov zoo ntawm cov duab kuaj mob.
Hauv cov raj xa duab X-ray uas tau ntawv pov thawj los ntawm CEI, lub tshuab lim dej tau raug kho kom zoo kom ntseeg tau tias tsuas yog cov duab X-ray zoo tshaj plaws mus txog tus neeg mob. Qhov no tsis yog tsuas yog txhim kho qhov zoo ntawm daim duab xwb tab sis kuj txo qhov kev raug hluav taws xob, ua raws li cov kev coj ua zoo tshaj plaws rau kev nyab xeeb ntawm tus neeg mob. Cov kws kho hniav tuaj yeem cia siab rau lub tshuab lim dej ntawm cov raj xa duab X-ray uas tau ntawv pov thawj los ntawm CEI kom tau txais cov txiaj ntsig zoo tshaj plaws thaum tiv thaiv kev noj qab haus huv ntawm tus neeg mob.
5. Vaj Huam Sib Luag
Lub vaj huam sib luag tswj hwm yog qhov sib txuas uas cov kws kho hniav siv lub tshuab X-ray. Nws tso cai rau kev hloov kho ntau yam kev teeb tsa, xws li lub sijhawm raug tshuaj ntsuam, lub raj tam sim no, thiab qhov hluav taws xob. Lub vaj huam sib luag tswj hwm yog qhov tseem ceeb rau kev kho kom haum rau txhua tus neeg mob cov kev xav tau tshwj xeeb thiab hom kev thaij duab xav tau.
Hauv cov raj xa duab X-ray uas tau ntawv pov thawj los ntawm CEI, lub vaj huam sib luag tswj tau tsim los kom sib npaug ntawm kev siv yooj yim thiab kev raug. Feem ntau nws muaj cov zaub digital thiab cov nyees khawm tswj uas yooj yim rau cov neeg ua haujlwm kho mob hloov kho sai. Qib kev tswj hwm no yog qhov tseem ceeb rau kev ua kom zoo ntawm cov duab X-ray uas tau tsim, pab txhawb kev kuaj mob thiab kev npaj kho mob kom raug.
xaus lus
Kev Kho HniavCov raj xa duab X-ray, tshwj xeeb tshaj yog cov uas tau ntawv pov thawj CEI, muaj ntau yam tseem ceeb uas ua haujlwm ua ke los tsim cov duab kuaj mob zoo. Kev nkag siab txog lub luag haujlwm ntawm cathode, anode, lub tsev iav, lub tshuab lim dej, thiab lub vaj huam sib luag tswj hwm yog qhov tseem ceeb rau cov kws kho hniav siv cov thev naus laus zis no hauv lawv txoj kev xyaum. Los ntawm kev ua kom muaj kev ua haujlwm zoo tshaj plaws ntawm cov khoom no, cov kws kho mob tuaj yeem muab kev saib xyuas zoo dua rau cov neeg mob thaum ua raws li cov qauv kev nyab xeeb. Thaum thev naus laus zis txuas ntxiv mus, qhov tseem ceeb ntawm cov raj X-ray hniav txhim khu kev qha thiab ua haujlwm tau zoo tsuas yog nce ntxiv; yog li ntawd, cov kws kho hniav yuav tsum paub txog cov kev txhim kho tshiab hauv daim teb.
