X-ray tshuabyog qhov tseem ceeb hauv kev kho mob, thiab ua cov chaw tsim khoom ntawm cov cuab yeej kho mob siab heev, Yueshen Medical nquag ua tau raws li cov neeg siv khoom xav tau rau kev teeb tsa. Txawm hais tias lawv siv dav, ntau tus neeg siv tseem muaj lus nug txog seb cov tshuab no ua haujlwm li cas. Tsab ntawv xov xwm no yog txhawm rau qhia meej txog kev tshaj lij ntawm cov tshuab X-ray, tsom mus rau lawv cov hauv paus ntsiab lus, hom, kev muaj peev xwm tshawb pom, thiab yam cuam tshuam rau lawv qhov kev nkag siab zoo.
Nkag siab txog X-ray Machine
- Discovery thiab Properties of X-rays
Wilhelm Conrad Roentgen, tus kws tshawb fawb German, nrhiav pom X-rays thaum lub Kaum Ib Hlis 8, 1895, thaum nws sim nrog cathode rays. X-rays yog lub zog muaj zog, nkag mus rau cov duab hluav taws xob uas tuaj yeem hla cov ntaub ntawv uas tsis tuaj yeem nkag mus rau lub teeb, xws li ntoo, iav, pob txha, thiab qee cov ntaub ntawv nyias nyias. Tshaj li daim ntawv thov kev kho mob, X-ray thev naus laus zis kuj tseem siv rau hauv kev kuaj xyuas kev nyab xeeb ntawm tshav dav hlau thiab hauv kev lag luam zaub mov, txhua yam raws li tib lub hauv paus ntsiab lus.
Cheebtsam thiab kev ua haujlwm
Lub tshuab X-ray muaj peb yam tseem ceeb:
- X-ray Generator: Qhov no yog lub plawv ntawm lub tshuab, lub luag hauj lwm rau tsim thiab emitting X-rays.
- X-ray Detectors: Ua los ntawm cov ntaub ntawv scintillator, cov cuab yeej no hloov X-rays rau hauv cov teeb pom kev zoo, nrog cov duab ntawm photodiodes raws li qhov sib txawv ntawm lub tshuab hluav taws xob.
- Control System: Qhov no tsom xam cov duab X-ray ntes los ntawm lub ntes, muab piv nrog cov qauv txheej txheem ua ntej hauv software los pab txhawb kev soj ntsuam thiab kev sib piv, zoo li lub koob yees duab sensor teb rau lub teeb.
Imaging Principple
- X-ray systems ua haujlwm raws li cov khoom siv tshuaj ntsuam xyuas, ntes cov duab ntawm tag nrho cov khoom thaum lub X-ray beam hla nws. Qhov ntsuas diode loj txiav txim siab seb cov khoom puas tau muab faib ua cov ntu me me rau kev soj ntsuam, nrog rau txhua ntu cov ntaub ntawv cov duab sawv cev hauv cov txiaj ntsig grey ntawm 0 txog 255. Qhov sib txawv ntawm qhov sib txawv hauv ib qho khoom nqus ntau qhov sib txawv ntawm X-rays, ua rau qhov sib piv ntawm cov txiaj ntsig grey uas tuaj yeem qhia tau tias muaj cov khoom txawv teb chaws.
Hom X-ray tshuab
Raws li tus naj npawb ntawm X-ray generators, cov cav tov tau muab faib ua:
- Tib Beam Systems: Cov no tau muab faib ntxiv raws li qhov irradiation txoj hauj lwm- ntsug, kab rov tav, lossis sab saum toj saib-uas haum rau ntau hom khoom thiab ntim.
- Ob Chav Beam Systems: Emitting X-rays los ntawm ob lub kaum ntse ntse, cov tshuab no ua rau kom muaj peev xwm nrhiav tau los ntawm kev muab cov duab los ntawm ntau qhov kev xav.
- Combined Beam Systems: Featuring ob txoj kab ntsug thiab kab rov tav, cov no txhim khu kev txheeb xyuas tus nqi rau cov khoom tshwj xeeb, xws li cov ntim hauv iav lossis hlau.
Kev kuaj pom muaj peev xwm ntawm X-ray tshuab
X-ray tshuab kuaj xyuas cov khoom txawv teb chaws los ntawm kev txheeb xyuas qhov sib txawv ntawm qhov sib txawv hauv qhov khoom. Qhov ntau dua qhov sib txawv ntawm qhov sib txawv ntawm cov khoom thiab cov khoom txawv teb chaws, nws yooj yim dua los kuaj xyuas. Piv txwv li, qhov sib txawv ntawm cov pob txha thiab cov nqaij mos hauv kev kho mob yog qhov txawv heev.
Factors Influencing Sensitivity
Ntau yam tuaj yeem cuam tshuam rau lub tshuab X-ray qhov rhiab heev rau cov khoom txawv teb chaws:
- Yam khoom yam ntxwv: Qhov ntom, tuab, thiab qhov sib xws ntawm cov khoom tuaj yeem cuam tshuam cov khoom txawv teb chaws yooj yim npaum li cas.
- Cov khoom txawv teb chaws: Qhov loj thiab qhov ntom ntawm cov khoom txawv teb chaws ua lub luag haujlwm tseem ceeb hauv kev txheeb xyuas qhov tseeb.
- Yam Ntxim Saib Ntxim Ua: Qhov sib thooj ntawm cov khoom txawv teb chaws mus rau X-ray qhov chaw tuaj yeem cuam tshuam qhov loj ntawm cov duab kos duab thiab kev tshawb pom qhov tshwm sim.
- Cov Khoom Siv Khaub Ncaws: Cov khoom siv ntawm ib qho khoom ntim sab nrauv tuaj yeem cuam tshuam rhiab heev.
- Cov Khoom Siv Precision: Qhov zoo ntawm X-ray raj, ntsuas diode qhov ntev, conveyor txoj siv, thiab calibration software tuaj yeem cuam tshuam rau lub tshuab qhov rhiab heev.
Optimizing X-ray tshuab Performance
Txhawm rau txhim kho kev tshawb pom rhiab heev, nws yog ib qho tseem ceeb uas yuav tau xav txog cov khoom muaj pes tsawg leeg thiab kho cov teeb tsa tshuab X-ray kom haum. Siv beryllium qhov rai X-ray raj rau cov khoom uas tsis tshua muaj siab, ua kom cov khoom siv conveyor tsis sib xws, thiab kev tswj xyuas cov software hloov kho tshiab yog txhua yam kev coj ua uas tuaj yeem txhim kho tus nqi ntsuas.
Hauv cov ntsiab lus, X-ray tshuab yog cov cuab yeej siv tau zoo uas siv cov hluav taws xob hluav taws xob siab kom nkag mus thiab luam theej duab cov khoom, muab cov kev pom tsis muaj txiaj ntsig hauv ntau qhov kev lag luam. Kev nkag siab txog lawv cov ntsiab cai, hom, thiab cov yam ntxwv cuam tshuam rau lawv qhov kev nkag siab zoo yog qhov tseem ceeb rau kev ua kom lawv cov txiaj ntsig zoo tshaj plaws thiab ua kom ntseeg tau qhov tseeb ntawm cov khoom txawv teb chaws.
