Hauv kev lag luam hluav taws xob, qhov tseeb thiab qhov tseeb yog qhov tseem ceeb tshaj plaws. Ib qho ntawm cov cuab yeej tseem ceeb rau kev ua tiav cov txiaj ntsig no yog phau ntawv X-ray collimator. Cov cuab yeej no ua lub luag haujlwm tseem ceeb hauv kev ua kom ntseeg tau tias X-ray beam raug coj mus rau thaj chaw lub hom phiaj, txo qis qhov cuam tshuam rau cov ntaub so ntswg, thiab txhim kho cov duab zoo. Hauv qhov blog no, peb yuav tshawb txog qhov tseem ceeb ntawm phau ntawv X-ray collimators, lawv lub luag haujlwm, thiab lawv qhov cuam tshuam rau tus neeg mob kev nyab xeeb thiab kuaj qhov tseeb.
Dab tsi yog phau ntawv X-ray collimator?
Ib phau ntawvX-ray collimatoryog ib qho cuab yeej txuas nrog rau X-ray raj uas pab tsim thiab kaw cov kab hluav taws xob X-ray. Los ntawm kev kho lub collimator, tus kws kho hluav taws xob tuaj yeem tswj qhov loj thiab cov duab ntawm cov hluav taws xob hluav taws xob, kom ntseeg tau tias tsuas yog cov cheeb tsam tsim nyog raug cuam tshuam rau X-rays. Qhov no yog qhov tseem ceeb tshwj xeeb hauv kev kuaj pom, qhov twg lub hom phiaj yog kom tau txais cov duab meej thaum txo qis qhov tsis tsim nyog raug hluav taws xob rau tus neeg mob.
Kev ua haujlwm ntawm phau ntawv X-ray collimator
Phau ntawv X-ray collimators ua haujlwm los ntawm kev hloov kho cov hlau lead. Cov shutters no tuaj yeem txav mus los ua ib lub voj voos lossis lub voj voos uas sib phim rau thaj chaw anatomical raug tshuaj xyuas. Tus kws kho hluav taws xob lossis tus kws tshaj lij tuaj yeem hloov kho lub collimator ua ntej ua qhov kev kuaj X-ray, muab qhov yooj yim los kho nws raws li qhov yuav tsum tau ua ntawm txhua qhov kev ntsuam xyuas.
Ib qho txiaj ntsig tseem ceeb ntawm phau ntawv collimators yog lawv qhov yooj yim thiab kev ntseeg tau. Tsis zoo li autocollimators, uas tej zaum yuav vam khom rau cov sensors thiab complex mechanisms, phau ntawv collimators muab ib tug ncaj txoj kev ntawm beam shaping. Qhov no yog qhov tshwj xeeb tshaj yog nyob rau hauv ib puag ncig uas siv tshuab yuav raug txwv lossis hauv cov xwm txheej uas yuav tsum tau hloov kho tam sim ntawd.
Txhim kho tus neeg mob kev nyab xeeb
Ib qho laj thawj tseem ceeb ntawm kev siv phau ntawv X-ray collimator yog txhawm rau txhim kho kev nyab xeeb ntawm tus neeg mob. Los ntawm kev txwv qhov chaw raug, lub collimator txo cov hluav taws xob tau txais los ntawm cov ntaub so ntswg nyob ib puag ncig. Qhov no yog ib qho tseem ceeb tshwj xeeb tshaj yog nyob rau hauv kev kho mob ntawm cov menyuam yaus, vim tias cov menyuam yaus muaj kev cuam tshuam rau cov hluav taws xob ntau dua thiab muaj kev pheej hmoo siab dua los ntawm kev tsim cov kab mob hluav taws xob vim lawv lub neej.
Tsis tas li ntawd, collimation pab txhim kho qhov zoo ntawm X-ray duab. Los ntawm kev tsom cov nqaj ntawm thaj tsam ntawm kev txaus siab, cov duab tshwm sim yog qhov pom tseeb thiab meej dua. Qhov kev pom tseeb no yog qhov tseem ceeb rau kev kuaj mob kom raug vim nws ua rau cov kws kho hluav taws xob txheeb xyuas qhov txawv txav thiab txiav txim siab paub txog kev saib xyuas neeg mob.
Ua raws li cov qauv kev cai
Hauv ntau lub tebchaws, cov koom haum tswj hwm tau tsim cov txheej txheem kev nyab xeeb hluav taws xob thiab cov qauv rau kev kuaj mob. Phau ntawv X-ray collimators ua lub luag haujlwm tseem ceeb hauv kev pab cov chaw kho mob ua raws li cov cai no. Los ntawm kev ua kom ntseeg tau tias tsuas yog thaj chaw tsim nyog tau raug hluav taws xob, cov neeg sib koom ua ke pab cov chaw kho mob nyob hauv kev ua raws li kev txwv koob tshuaj thiab txo qis kev pheej hmoo ntawm overexposure.
nyob rau hauv xaus
Hauv cov ntsiab lus,phau ntawv X-ray collimatorsyog ib qho cuab yeej tseem ceeb hauv kev lag luam hluav taws xob. Lawv lub peev xwm los tswj cov X-ray beam tsis tsuas yog txhim kho cov duab zoo xwb, tab sis kuj tseem ua rau cov neeg mob muaj kev nyab xeeb los ntawm kev txo cov hluav taws xob tsis tsim nyog. Raws li kev siv thev naus laus zis txuas ntxiv mus, cov hauv paus ntsiab lus ntawm kev sib tsoo tseem ceeb heev kom ntseeg tau tias kev siv hluav taws xob ua raws li cov qauv kev nyab xeeb thiab muab kev saib xyuas zoo tshaj plaws rau cov neeg mob. Txawm nyob hauv tsev kho mob tsis khoom lossis chaw kho mob me, phau ntawv X-ray collimators tseem yuav yog ib qho tseem ceeb ntawm kev kuaj pom zoo.
