Hauv thaj chaw ntawm radiography, x-ray tube vaj tse ua lub luag haujlwm tseem ceeb hauv kev ua kom pom tseeb thiab kev nyab xeeb ntawm cov neeg mob thiab cov kws kho mob. Los ntawm kev tiv thaiv hluav taws xob kom tswj tau qhov chaw ua haujlwm kom zoo, qhov blog no tshawb txog ntau yam khoom thiab kev ua haujlwm ntawm X-ray raj vaj tse.
1. X-ray hluav taws xob tiv thaiv:
Thaum muab cov duab zoo, cov x-ray raj vaj tse ua raws li cov ntaub thaiv npog los ntawm cov hluav taws xob tsis zoo uas tawm thaum lub sijhawm ua duab. Lub tsev yog tsim nrog cov ntaub ntawv tuab tuab uas nqus tau feem ntau ntawm cov xoo hluav taws xob emission, txo qhov kev cuam tshuam rau ionizing hluav taws xob. Ntxiv rau kev tiv thaiv ib puag ncig ib puag ncig, nws kuj tseem tiv thaiv cov khoom tawg yooj yim hauv lub raj, ua kom nws ruaj khov.
2. Dielectric roj:
Dielectric roj yog ib qho tseem ceeb ntawm cov rojX-ray tube vaj tse. Nws ua raws li hluav taws xob insulator, tiv thaiv tam sim no los ntawm qhov sib txawv ntawm cov raj. Cov roj kuj tseem pab kom txias rooj plaub, pab tiv thaiv kom tsis txhob muaj cua sov. Kev saib xyuas tsis tu ncua thiab kev saib xyuas ntawm cov roj dielectric yog qhov tseem ceeb los xyuas kom meej tias kev ua haujlwm zoo thiab tsis txhob muaj kev puas tsuaj.
3. Kev ua haujlwm huab cua:
Kev tswj xyuas qhov chaw ua haujlwm kom zoo hauv X-ray tube kaw yog qhov tseem ceeb rau kev ua haujlwm kom raug. Cov huab cua feem ntau yog tswj los txhim kho hluav taws xob rwb thaiv tsev thiab cua txias. Cov huab cua siab nyob rau hauv lub enclosure yuav tsum tau saib xyuas thiab tswj kom tsis txhob tsim cov pa npuas uas cuam tshuam rau X-ray beam tiam.
4. Kho lub raj tam sim no:
Kev siv hluav taws xob hluav taws xob hluav taws xob tuaj yeem tswj tau los ntawm kev hloov kho tam sim no los ntawm X-ray raj sib dhos. Los ntawm kev tswj cov raj tam sim no, cov kws yees duab hluav taws xob tuaj yeem txhim kho cov duab zoo thaum txo cov neeg mob raug hluav taws xob tsawg. Pom zoo cov lus qhia noj tshuaj yuav tsum tau ua raws li thiab lub tshuab x-ray calibrated ib ntus kom paub meej tias qhov kev hloov kho tam sim no raug.
5. X-ray raj plhaub kub:
Kev tswj xyuas qhov kub kom zoo hauv X-ray raj vaj tsev yog qhov tseem ceeb rau kev ua haujlwm thiab kev ua haujlwm ntev. Cov cua kub ntau dhau tuaj yeem ua rau qhov ua tau zoo ntawm cov khoom siv sab hauv, uas tuaj yeem ua rau lub cev tsis zoo lossis cov duab tsis zoo. Ua raws li kev saib xyuas thiab kev ua kom txias, xws li cov kiv cua lossis cov ntsuas kub ntsuas, kom cov ntaub thaiv nyob rau hauv qhov kub thiab txias.
6. Kev txwv kev ua haujlwm:
X-ray tube vaj tsemuaj cov kev txwv tshwj xeeb uas tau teev tseg los ntawm cov chaw tsim khoom. Cov kev txwv no suav nrog cov yam ntxwv xws li qhov siab tshaj plaws lub raj hluav taws xob, lub voj voog tam sim no thiab lub luag haujlwm. Kev ua raws li cov kev txwv no yog qhov tseem ceeb los tiv thaiv kev puas tsuaj hauv vaj tse thiab ua kom cov duab zoo ib yam thiab txhim khu kev qha. Kev tshuaj xyuas thiab kev saib xyuas tsis tu ncua pab txheeb xyuas qhov muaj peev xwm ua txhaum cai ntawm kev ua haujlwm txwv thiab ua kom tsim nyog hloov kho.
7. Qhia qhov txhaum:
Txawm tias muaj kev saib xyuas tsis tu ncua, kev ua haujlwm tsis zoo lossis qhov txawv txav tuaj yeem tshwm sim hauv X-ray raj vaj tsev. Yuav tsum muaj ib qho kev kuaj mob hauv qhov chaw txhawm rau txheeb xyuas qhov sib txawv ntawm kev ua haujlwm ib txwm muaj. Ua raws li kev soj ntsuam tsis tu ncua thiab kev tswj xyuas cov txheej txheem kom sai txheeb xyuas thiab daws txhua yam teeb meem, kom ntseeg tau tias tsis muaj kev cuam tshuam thiab raug kev pabcuam hluav taws xob.
8. Pov tseg:
Thaum X-ray raj vaj tse mus txog qhov kawg ntawm nws lub neej voj voog lossis dhau los lawm, yuav tsum ua raws li cov txheej txheem pov tseg. Cov kev cai e-pov tseg yuav tsum tau ua raws li vim muaj peev xwm muaj cov khoom phom sij xws li txhuas. Kev txiav txim siab yuav tsum tau muab rau kev rov ua dua lossis hu rau cov kev pabcuam pov tseg kom txo qis kev cuam tshuam rau ib puag ncig.
nyob rau hauv xaus:
X-ray tube vaj tse ua lub luag haujlwm tseem ceeb hauv kev tiv thaiv hluav taws xob tsis zoo thiab ua kom muaj kev ua tau zoo ntawm cov txheej txheem radiography. Los ntawm kev nkag siab txog qhov tseem ceeb ntawm txhua lub ntsiab lus thiab ua raws li cov txheej txheem ua haujlwm, cov kws kho mob tuaj yeem ua kom muaj kev nyab xeeb, muaj tseeb rau cov neeg mob. Kev saib xyuas tsis tu ncua, kev saib xyuas, thiab ua raws li cov lus pom zoo thiab cov kev txwv yog qhov tseem ceeb rau kev muab kev saib xyuas siab tshaj plaws thiab txo qis kev pheej hmoo cuam tshuam nrog X-ray hluav taws xob.
