X-ray thev naus laus zis tau dhau los ntev txij li nws qhov kev tsim tawm thaum xyoo pua 19th lig.Niaj hnub no, X-ray imaging yog siv rau ntau yam kev kuaj mob thiab kev kho mob lub hom phiaj hauv tshuaj, kho hniav, thiab ntau yam hauj lwm.Ib qho tseem ceeb ntawm cov tshuab X-ray niaj hnub no yog qhovduab intensifier, uas txhim kho qhov zoo thiab pom tseeb ntawm X-ray duab.
Ntawm nws cov theem pib tshaj plaws, X-ray duab intensifier ua haujlwm los ntawm kev nthuav dav me me ntawm lub teeb uas tsim los ntawm X-ray photons thaum lawv dhau los ntawm tus neeg mob lub cev.Lub intensifier ces converts lub teeb no mus rau hauv ib tug hluav taws xob teeb liab, uas yuav siv tau los tsim ib tug txhim khu kev qha duab ntawm ib tug zaub screen.Cov duab intensifiers tau siv ntau yam khoom siv X-ray, suav nrog fluoroscopes, cov khoom siv hluav taws xob, thiab CT scanners.
Fluoroscopes
Fluoroscopy yog ib hom kev kuaj X-ray uas siv cov kab hluav taws xob txuas ntxiv ntawm X-rays los tsim cov duab tiag tiag ntawm tus neeg mob lub cev thiab cov ntaub so ntswg.Fluoroscopes feem ntau yog siv rau hauv cov txheej txheem phais thiab kev cuam tshuam, nrog rau kev kuaj mob xws li mob plab hnyuv thiab mob musculoskeletal.
Cov duab intensifiers yog ib qho tseem ceeb ntawm cov khoom siv fluoroscopy, vim lawv txhim kho qhov pom thiab kev daws teeb meem ntawm cov duab tsim.Los ntawm kev ua kom qhov sib txawv thiab ci ntsa iab ntawm cov duab X-ray, cov duab intensifiers tso cai rau cov kws kho mob thiab cov kws kho hluav taws xob pom zoo rau cov qauv sab hauv thiab txheeb xyuas cov teeb meem uas yuav tshwm sim.
Cov khoom siv hluav taws xob
Radiography yog lwm hom X-ray imaging, uas siv cov tawg luv luv ntawm X-rays los tsim cov duab tseem ceeb ntawm tus neeg mob lub cev.Radiographs feem ntau yog siv los kuaj mob xws li pob txha, qog, thiab mob ntsws.
Zoo li fluoroscopes, cov cuab yeej siv hluav taws xob niaj hnub no feem ntau suav nrog cov duab intensifiers txhawm rau txhim kho qhov zoo ntawm cov duab tsim.Los ntawm kev ua kom qhov rhiab heev thiab kev daws teeb meem ntawm X-ray detector, cov duab intensifiers tuaj yeem pab cov kws kho mob thiab cov kws kho hluav taws xob tsim cov duab kos duab kom ntxaws thiab meej.
CT Scanners
Ntxiv nrog rau fluoroscopy thiab radiography, X-ray duab intensifiers kuj tau siv hauv CT (computed tomography) scanners.CT scanners siv lub teeb X-ray tig los tsim cov duab sib luag ntawm tus neeg mob lub cev.
Cov duab intensifiers feem ntau yog siv nyob rau hauv lub ntes array ntawm CT scanners, qhov chaw uas lawv amplify lub X-ray photons pom los ntawm lub system.Qhov no tso cai rau CT scanners los tsim cov duab zoo, kev daws teeb meem siab ntawm tus neeg mob cov qauv sab hauv, ua rau lawv muaj txiaj ntsig zoo rau kev kuaj mob ntau yam.
Xaus
X-ray duab intensifiers yog ib qho tseem ceeb ntawm cov tshuab X-ray niaj hnub, txhim kho qhov zoo thiab pom tseeb ntawm cov duab kuaj mob rau ntau yam kev siv kho mob thiab kev tshawb fawb.Los ntawm cov khoom siv fluoroscopes thiab cov khoom siv hluav taws xob mus rau CT scanners, cov duab intensifiers tau hloov kho qhov chaw ntawm X-ray duab, ua kom yooj yim dua thiab raug dua los kuaj xyuas thiab kho ntau yam mob.Raws li kev siv thev naus laus zis txuas ntxiv mus, nws yuav zoo li X-ray duab intensifiers yuav txuas ntxiv ua lub luag haujlwm tseem ceeb hauv kev kho mob rau ntau xyoo tom ntej.
