Hauv kev kho mob niaj hnub no, kev tshuaj ntsuam xyuas ua lub luag haujlwm tseem ceeb hauv kev saib xyuas tus neeg mob, tso cai rau cov kws kho mob kom pom cov qauv sab hauv ntawm lub cev. Ntawm ntau yam kev ntsuas kev ntsuas, X-ray duab tseem yog ib qho ntawm cov kev siv dav tshaj plaws. Hauv plawv ntawm lub tshuab no yog lub raj xa hluav taws xob kho mob, ib qho cuab yeej uas tau hloov kho txoj kev peb kuaj thiab kho mob.
X-ray tube yog dab tsi?
A kho mob X-ray tubeyog lub tshuab nqus tsev tshwj xeeb uas tsim cov X-rays los ntawm kev sib cuam tshuam ntawm cov hluav taws xob hluav taws xob siab nrog cov khoom siv lub hom phiaj, feem ntau yog ua los ntawm tungsten. Thaum siv hluav taws xob tam sim no, electrons raug tso tawm los ntawm cov cathode rhuab thiab nrawm mus rau lub anode. Tom qab tawm tsam lub anode, cov hluav taws xob ceev ceev no sib tsoo nrog cov khoom siv, ua X-rays hauv cov txheej txheem. Qhov txheej txheem yooj yim no tso cai rau peb khaws cov duab ntawm cov pob txha, lub cev, thiab cov ntaub so ntswg hauv tib neeg lub cev.
Cheebtsam ntawm X-Ray Tubes
Kev nkag siab txog cov khoom ntawm lub raj xa hluav taws xob kho mob yog qhov tseem ceeb rau kev nkag siab txog nws txoj haujlwm. Cov feem tseem ceeb muaj xws li:
- Cathode: Cov khoom no muaj cov filament uas yog rhuab los tsim cov electrons. Lub cathode yog qhov tseem ceeb rau kev pib X-ray tiam txheej txheem.
- Anode: Lub anode ua lub hom phiaj rau cathode emit electrons. Nws feem ntau yog ua los ntawm tungsten vim nws cov ntsiab lus melting siab thiab kev ua tau zoo hauv kev tsim X-rays.
- Lub hnab ntawv iav lossis hlau: Tag nrho lub rooj sib txoos yog nyob rau hauv lub hnab ntawv lub tshuab nqus tsev, uas tiv thaiv cov hluav taws xob los ntawm kev sib tsoo nrog huab cua molecules thiab ua kom muaj txiaj ntsig X-ray tiam.
- Lim: Txhawm rau txhim kho cov duab zoo thiab txo cov neeg mob raug hluav taws xob tsis tsim nyog, cov ntxaij lim dej yog siv los tshem tawm cov hluav taws xob xoo hluav taws xob tsawg uas tsis ua rau cov ntaub ntawv kuaj mob.
- Collimator: Cov cuab yeej no tsim thiab txwv cov kab hluav taws xob X-ray, kom ntseeg tau tias tsuas yog cov chaw tsim nyog raug nthuav tawm thaum lub sijhawm ua duab.
Qhov tseem ceeb ntawm X-Ray Tubes hauv Kev Kho Mob
Kev kho mob X-ray raj yog qhov tseem ceeb hauv ntau qhov chaw kho mob. Lawv muaj ntau yam kev siv xws li:
- Kev kuaj mob pob txha: X-rays yog thawj kab ntawm kev ntsuam xyuas rau qhov xav tias puas muaj pob txha thiab tuaj yeem soj ntsuam cov pob txha puas tsuaj sai thiab raug.
- Kev kuaj mob qog: X-ray duab tuaj yeem pab txheeb xyuas qhov txawv txav lossis qog nqaij hlav, coj cov txheej txheem kuaj mob ntxiv.
- Kev kho hniav imaging: Hauv kev kho hniav, X-ray raj yog siv los ntes cov duab ntawm cov hniav thiab cov qauv nyob ib puag ncig los pab kuaj cov teeb meem hniav.
- Lub hauv siab imaging: Lub hauv siab X-ray feem ntau yog siv los ntsuas qhov mob ntawm lub ntsws, lub plawv loj, thiab lwm yam hauv siab txawv txav.
Kev nce qib hauv X-Ray Tube Technology
Kev kho mob kev kho mob tseem tab tom hloov zuj zus, thiab cov thev naus laus zis cuam tshuam nrog X-ray raj. Cov kev nce qib tsis ntev los no suav nrog kev txhim kho digital X-ray tshuab uas txhim kho cov duab zoo, txo cov hluav taws xob raug hluav taws xob, thiab ua kom lub sijhawm ua haujlwm luv. Tsis tas li ntawd, cov thev naus laus zis tshiab xws li cov tshuab xoo hluav taws xob xa hluav taws xob tuaj yeem ua kom pom tau hauv ntau qhov chaw, suav nrog chav xwm txheej ceev thiab chaw nyob deb.
nyob rau hauv xaus
Medical X-ray tubesyog ib feem tseem ceeb ntawm kev kuaj mob, muab cov kws kho mob nrog cov cuab yeej uas lawv xav tau los txiav txim siab txog kev saib xyuas neeg mob. Raws li kev siv thev naus laus zis txuas ntxiv mus, lub peev xwm ntawm X-ray raj tsuas yog txuas ntxiv txhim kho, ua rau muaj qhov tseeb dua thiab kho cov neeg mob tau zoo. Kev nkag siab txog kev ua haujlwm thiab qhov tseem ceeb ntawm cov cuab yeej no yog qhov tseem ceeb rau txhua tus neeg uas xav paub txog kev kho mob, vim tias lawv sawv cev rau lub hauv paus ntawm kev kuaj mob niaj hnub no. Txawm nyob hauv tsev kho mob, tsev kho mob lossis chaw kho hniav, cov raj xa hluav taws xob kho mob yuav tseem yog ib feem tseem ceeb ntawm kev kho mob rau xyoo tom ntej.
