Cov Hlab X-Ray: Cov Cheebtsam Tseem Ceeb thiab Kev Ua Haujlwm hauv Kev X-Ray

Cov raj xa duab X-rayyog ib feem tseem ceeb ntawm kev thaij duab radiology thiab ua lub luag haujlwm tseem ceeb hauv kev tsim cov duab X-ray siv hauv kev thaij duab kho mob. Kev nkag siab txog cov khoom tseem ceeb thiab kev ua haujlwm ntawm lub raj X-ray yog qhov tseem ceeb rau cov kws tshaj lij radiology thiab cov kws kho mob koom nrog kev thaij duab kuaj mob. Tsab xov xwm no yuav muab kev saib tob txog cov khoom tseem ceeb thiab kev ua haujlwm ntawm cov raj X-ray hauv kev thaij duab radiology, piav qhia txog lawv qhov tseem ceeb hauv kev kuaj mob.

Cov khoom tseem ceeb ntawm lub raj xa duab X-ray:

1. Cathode: Lub cathode yog ib qho tseem ceeb ntawm lub raj X-ray thiab yog lub luag haujlwm rau kev tso tawm cov electrons. Nws muaj ib lub filament thiab ib lub khob tsom. Thaum muaj hluav taws xob siab, lub filament kub, ua rau nws tso tawm cov electrons. Lub khob tsom pab coj cov electrons no mus rau lub anode.

2. Anode: Lub anode yog lwm yam tseem ceeb ntawm lub raj X-ray. Nws feem ntau yog ua los ntawm tungsten vim nws lub ntsiab lus yaj siab. Thaum cov electrons los ntawm cathode ntaus lub anode, X-rays raug tsim los ntawm cov txheej txheem ntawm Bremsstrahlung. Lub anode kuj tseem ua haujlwm los tshem tawm cov cua sov tsim tawm thaum lub sijhawm txheej txheem.

3. Lub thawv iav: Lub raj xa duab X-ray raug teeb tsa rau hauv lub thawv iav, uas puv nrog lub tshuab nqus tsev kom tiv thaiv kev tawg ntawm cov hluav taws xob thiab pab txhawb kev tsim cov duab X-ray.

Kev ua haujlwm ntawm cov raj xa hluav taws xob X-ray hauv kev thaij duab:

1. Tsim cov duab X-ray: Lub luag haujlwm tseem ceeb ntawm lub raj X-ray yog tsim cov duab X-ray los ntawm kev sib cuam tshuam ceev ceev ntawm cov hluav taws xob cathode thiab anode. Cov txheej txheem no tsim cov duab X-rays uas siv los thaij duab ntau qhov ntawm lub cev tib neeg.

2. Kev tso cua sov tawm: Thaum cov hluav taws xob ntaus lub anode, muaj cua sov ntau heev. Lub anode no tau tsim los kom tig sai sai kom tso cua sov tawm thiab tiv thaiv kev puas tsuaj rau lub raj X-ray.

3. Kev Tswj Xyuas Cov Duab X-ray: Cov raj X-ray muaj cov kev tswj kom kho cov yam ntxwv ntawm kev raug mob xws li kilovolts (kV) thiab milliampere vib nas this (mAs). Cov kev tswj no tso cai rau cov kws kho mob radiology kho cov duab X-ray raws li txhua tus neeg mob xav tau kev thaij duab tshwj xeeb.

4. Qhov loj ntawm qhov tsom xam: Qhov loj ntawm qhov tsom xam anode ua lub luag haujlwm tseem ceeb hauv kev txiav txim siab qhov kev daws teeb meem ntawm cov duab X-ray. Cov ntsiab lus tsom xam me me tsim cov duab daws teeb meem siab dua, yog li kev tswj hwm thiab tswj qhov loj ntawm qhov tsom xam yog qhov tseem ceeb rau qhov zoo tshaj plaws ntawm kev kuaj mob.

5. Lub Tsev Rau Lub Raj Thiab Collimation: Lub raj X-ray nyob hauv lub tsev tiv thaiv uas muaj lub collimator los kaw lub teeb X-ray rau thaj chaw uas xav tau thiab txo qhov kev raug hluav taws xob tsis tsim nyog rau tus neeg mob.

Hauv kev xaus,Cov raj xa duab X-rayyog ib feem tseem ceeb ntawm kev siv duab hluav taws xob, thiab kev nkag siab txog lawv cov khoom tseem ceeb thiab kev ua haujlwm yog qhov tseem ceeb rau cov kws kho mob uas koom nrog kev kuaj mob. Los ntawm kev nkag siab txog cov haujlwm ntawm cathodes, anodes, thiab lwm yam khoom nrog rau kev ua haujlwm koom nrog kev tsim thiab tswj X-ray, cov kws kho mob radiology tuaj yeem ua kom muaj kev nyab xeeb thiab siv tau zoo ntawm cov raj X-ray rau kev kuaj mob kom raug. Kev paub no thaum kawg pab txhawb rau kev muab kev saib xyuas tus neeg mob zoo thiab kev nce qib ntawm cov thev naus laus zis kho mob.
