DR flat vaj huam sib luag ntes ua haujlwm txoj cai
Lub vaj huam sib luag tiaj tus ntes yog ib qho khoom siv nyuaj thiab kim, uas ua lub luag haujlwm txiav txim siab hauv cov duab zoo. Kev paub txog kev ntsuas ntsuas kev ua tau zoo tuaj yeem pab txhim kho cov duab zoo thiab txo cov koob tshuaj X-ray.
Cov duab hluav taws xob digital (DR) yog cov thev naus laus zis tshiab tsim los rau cov duab hluav taws xob hauv xyoo 1990. Nrog nws cov duab nrawm dua, kev ua haujlwm yooj yim dua, cov duab daws teeb meem siab dua thiab lwm yam zoo, nws tau dhau los ua tus thawj coj hauv cov duab hluav taws xob digital thiab tau lees paub los ntawm cov kws kho mob thiab cov kws paub txog duab thoob ntiaj teb. .
Cov thev naus laus zis tseem ceeb ntawm DR yog lub ntsuas vaj huam sib luag tiaj tus. Lub vaj huam sib luag tiaj tus ntes yog ib qho khoom siv nyuaj thiab kim uas ua lub luag haujlwm txiav txim siab hauv cov duab zoo. Kev paub txog cov ntsuas ntsuas kev ua tau zoo yuav pab peb txhim kho cov duab zoo thiab txo cov koob tshuaj X-ray
Flat panel detectors muaj xws li vaj tse (txheej txheej), txheej fluorescence, lub rooj tsavxwm thiab lub dab dej kub. Cov txheej fluorescence tau muab faib ua CSI thiab GDS (GDOS{0}}). CSI phosphor txheej qhia pom cov duab meej dua, thaum GDS phosphor screen yog qhov nkag siab dua.
Raws li cov khoom siv semiconductor, nws tuaj yeem muab faib ua amorphous selenium ca vaj huam sib luag ntes thiab amorphous silicon ca vaj huam sib luag ntes. Amorphous selenium ca vaj huam sib luag detectors muaj siab rhiab heev thiab feem ntau yog siv rau dynamic panels.
Raws li kev faib tawm ntawm cov duab software, tuaj yeem muaj software kho mob, tsiaj software thiab cov software tsim khoom.
Thaum siv cov ntsuas vaj huam sib luag tiaj tus, nws yuav tsum raug sau tseg tias qhov ntsuas kub zoo tshaj plaws rau lub vaj huam sib luag tiaj tiaj ua haujlwm yog 5 degree txog 35 degree. Nyob rau hauv cov ntaub ntawv ntawm kev siv nyob rau hauv tropical cheeb tsam, kev tswj cua txias yuav tsum tau siv. Tsis tas li ntawd, mloog yuav tsum tau them rau cov nyhuv etching. Lub neej theoretical ntawm lub vaj huam sib luag ntes yog 3 xyoos. Kev siv lub sij hawm ntev ntawm lub vaj huam sib luag ntes tau tuaj yeem tsim cov khoom cuav uas tsis tuaj yeem raug tshem tawm vim cov nyhuv etching, yog li cuam tshuam rau cov duab zoo.
