Txawm li cas los xij, qhov ua tau zoo ntawm kev siv tshuab X-ray nyob ntawm qhov tseeb ntawm cov khoom siv, tshwj xeeb tshaj yog cov tshuab X-ray collimators. Cov khoom siv no ua lub luag haujlwm tseem ceeb hauv kev txhim kho qhov tseeb ntawm kev kuaj mob los ntawm kev tswj cov duab thiab qhov loj ntawm lub teeb X-ray, yog li txo qhov kev raug tsis tsim nyog thiab txhim kho qhov zoo ntawm daim duab.
Kawm txog X-ray collimators
Cov khoom siv X-ray collimatorsyog cov khoom siv uas tau teeb tsa rau ntawm lub raj X-ray uas siv los ua kom lub teeb hluav taws xob tso tawm thaum lub sijhawm thaij duab. Los ntawm kev txwv thaj chaw uas raug rau X-rays, collimators pab tsom cov hluav taws xob rau cov cheeb tsam tshwj xeeb, uas yog qhov tseem ceeb rau kev tau txais cov duab meej thiab ntxaws. Txoj hauv kev tsom mus rau qhov no tsis yog tsuas yog txhim kho qhov zoo ntawm cov duab tsim tawm, tab sis kuj txo cov koob tshuaj hluav taws xob rau cov ntaub so ntswg ib puag ncig, yog li txo qis kev pheej hmoo ntawm cov teeb meem cuam tshuam nrog hluav taws xob.
Zoo dua daim duab zoo dua
Ib txoj hauv kev tseem ceeb uas lub tshuab X-ray collimator txhim kho qhov tseeb ntawm kev kuaj mob yog los ntawm kev txhim kho qhov zoo ntawm daim duab. Thaum lub teeb X-ray raug collimated, nws txo cov hluav taws xob tawg, uas tuaj yeem ua rau cov ntsiab lus tsis meej hauv daim duab. Cov hluav taws xob tawg tshwm sim thaum cov duab X-rays cuam tshuam nrog cov khoom thiab tig ntawm lawv txoj kev qub, ua rau daim duab tsis meej ntawm daim duab xoo hluav taws xob. Los ntawm kev tsom lub teeb nrog lub collimator, cov kws kho mob xoo hluav taws xob tuaj yeem tau txais cov duab meej dua, muaj qhov sib txawv siab dua, ua rau nws yooj yim dua los txheeb xyuas cov teeb meem xws li qog nqaij hlav, pob txha tawg, lossis kev kis kab mob.
Txo kev raug hluav taws xob
Ntxiv rau kev txhim kho qhov zoo ntawm daim duab, cov tshuab X-ray collimators kuj tseem ua lub luag haujlwm tseem ceeb hauv kev txo cov neeg mob raug hluav taws xob. Kev siv hluav taws xob tsis tsim nyog ua rau muaj kev pheej hmoo loj rau kev noj qab haus huv, tshwj xeeb tshaj yog thaum lub sijhawm rov ua dua cov txheej txheem thaij duab. Los ntawm kev txwv lub teeb X-ray rau thaj chaw uas xav tau, lub tshuab collimator ua kom ntseeg tau tias tsuas yog cov ntaub so ntswg tsim nyog raug irradiated. Qhov no tsis yog tsuas yog tiv thaiv tus neeg mob xwb, tab sis kuj ua raws li ALARA (Qis Tshaj Plaws Li Qhov Ua Tau), ib qho kev qhia tseem ceeb hauv kev kho mob uas lub hom phiaj yog txo qis kev raug hluav taws xob.

Hauv kev xaus lus
Hauv kev xaus,Cov khoom siv X-ray collimatorsyog ib qho cuab yeej tseem ceeb hauv kev tshawb fawb txog kev siv hluav taws xob uas tuaj yeem txhim kho qhov tseeb ntawm kev kuaj mob. Los ntawm kev tsom mus rau lub teeb X-ray, cov khoom siv no tuaj yeem txhim kho qhov zoo ntawm cov duab, txo qhov kev raug hluav taws xob tsis tsim nyog, thiab pab txhawb kev kuaj mob kom raug dua. Thaum thev naus laus zis txuas ntxiv mus, cov collimators yuav txuas ntxiv ua lub luag haujlwm tseem ceeb hauv kev ua kom ntseeg tau tias kev coj ua ntawm kev siv hluav taws xob ua raws li cov qauv siab tshaj plaws ntawm kev nyab xeeb ntawm tus neeg mob thiab kev kuaj mob kom raug. Kev koom ua ke ntawm cov thev naus laus zis collimation zoo tsis yog tsuas yog pab cov neeg mob xwb, tab sis kuj tseem ua rau cov kws kho mob muab kev saib xyuas zoo dua los ntawm kev thaij duab kom raug.
