X-ray thev naus laus zis tau hloov pauv txoj haujlwm ntawm kev kho mob duab, muab cov kws kho mob nrog kev nkag siab tseem ceeb rau tib neeg lub cev. Txawm li cas los xij, qhov ua tau zoo ntawm X-ray duab nyob ntawm qhov tseeb ntawm cov cuab yeej siv, tshwj xeeb tshaj yog X-ray collimators. Cov cuab yeej no ua lub luag haujlwm tseem ceeb hauv kev txhim kho qhov tseeb ntawm kev kuaj hluav taws xob los ntawm kev tswj cov duab thiab qhov loj ntawm X-ray beam, yog li txo qis qhov tsis tsim nyog raug thiab txhim kho cov duab zoo.
Kawm txog X-ray collimators
X-ray collimatorsyog cov cuab yeej mounted rau ntawm X-ray raj uas yog siv los nqaim cov kab hluav taws xob hluav taws xob tawm thaum lub sij hawm duab. Los ntawm kev txwv qhov chaw raug rau X-rays, collimators pab tsom cov hluav taws xob ntawm cov kev txaus siab tshwj xeeb, uas yog qhov tseem ceeb kom tau txais cov duab meej thiab ntxaws. Qhov kev tsom mus rau qhov no tsis yog tsuas yog txhim kho qhov zoo ntawm cov duab tsim, tab sis kuj txo cov koob tshuaj hluav taws xob rau cov ntaub so ntswg ib puag ncig, yog li txo qhov kev pheej hmoo ntawm cov teeb meem hluav taws xob cuam tshuam.
Txhim kho duab zoo
Ib txoj hauv kev tseem ceeb ntawm X-ray collimator txhim kho qhov tseeb ntawm kev kuaj mob yog los ntawm kev txhim kho cov duab zoo. Thaum X-ray beam collimated, nws txo cov hluav taws xob tawg, uas tuaj yeem pom cov ntsiab lus hauv daim duab. Cov tawg tawg tawg tshwm sim thaum X-rays cuam tshuam nrog cov teeb meem thiab sib txawv ntawm lawv txoj kev qub, ua rau pom qhov muag plooj ntawm lub xov tooj cua. Los ntawm kev tsom cov nqaj nrog lub collimator, cov kws kho hluav taws xob tuaj yeem tau txais cov duab meej dua, zoo dua qub, ua kom yooj yim dua los txheeb xyuas qhov txawv txav xws li qog, pob txha, lossis kab mob.
Txo qhov raug hluav taws xob
Ntxiv nrog rau kev txhim kho cov duab zoo, X-ray collimators kuj ua lub luag haujlwm tseem ceeb hauv kev txo cov neeg mob hluav taws xob. Cov hluav taws xob tsis tsim nyog ua rau muaj kev phom sij loj rau kev noj qab haus huv, tshwj xeeb tshaj yog thaum rov ua cov txheej txheem duab. Los ntawm kev txwv lub X-ray beam rau thaj tsam ntawm kev txaus siab, lub collimator xyuas kom meej tias tsuas yog cov ntaub so ntswg tsim nyog yog irradiated. Qhov no tsis yog tsuas yog tiv thaiv tus neeg mob xwb, tab sis kuj ua raws li ALARA (Raws Li Tsawg Li Ua Tau), cov lus qhia tseem ceeb hauv kev siv hluav taws xob uas lub hom phiaj txo qis hluav taws xob tsawg.
Yooj yim rau kev kuaj mob kom raug
Txhim kho cov duab zoo thiab txo cov hluav taws xob raug ncaj qha txhim kho qhov tseeb ntawm kev kuaj mob. Radiologists cia siab rau cov duab zoo los txiav txim siab txog kev saib xyuas neeg mob. Thaum cov duab pom tseeb thiab tsis muaj cov khoom cuav uas tshwm sim los ntawm cov hluav taws xob tawg, nws yooj yim dua los xyuas cov kev hloov pauv hloov hauv lub cev lossis cov kab mob pathology. Qhov tseeb no yog qhov tseem ceeb tshwj xeeb tshaj yog thaum kuaj xyuas cov kab mob xws li mob qog noj ntshav, qhov kev tshawb pom ntxov tuaj yeem cuam tshuam txog kev kho mob.
Hauv cov ntsiab lus
Hauv cov ntsiab lus,X-ray collimatorsyog ib qho cuab yeej tseem ceeb hauv kev lag luam hluav taws xob uas tuaj yeem txhim kho qhov tseeb ntawm kev kuaj mob. Los ntawm kev tsom mus rau X-ray beam, cov cuab yeej no tuaj yeem txhim kho cov duab zoo, txo cov hluav taws xob tsis tsim nyog, thiab pab txhawb kev kuaj mob kom raug. Raws li kev siv thev naus laus zis txuas ntxiv mus, collimators yuav txuas ntxiv ua lub luag haujlwm tseem ceeb hauv kev ua kom ntseeg tau tias kev siv hluav taws xob ua raws li cov qauv siab tshaj plaws ntawm tus neeg mob kev nyab xeeb thiab kev kuaj pom tseeb. Kev sib koom ua ke ntawm cov cuab yeej sib tsoo zoo tsis yog tsuas yog muaj txiaj ntsig zoo rau cov neeg mob, tab sis kuj tseem ua rau cov kws kho mob muab kev saib xyuas zoo dua los ntawm kev ntsuas qhov tseeb.
