Qhov sib txawv ntawmDuab Txhuam Siabthiabtiaj tus txiv huam sib luag detectors.Tooj teb ntawmKev Kho Mob, X-Rays ua ib lub luag haujlwm tseem ceeb hauv kev kuaj thiab kho ntau yam kab mob thiab kev raug mob. Kev nce qib hauv thev naus laus zis tau ua rau kev txhim kho ntawm cov duab xoo hluav taws xob ntau dua ntes cov khoom siv. Ob qho kev nrhav tshiab yog cov duab ua kom zoo thiab vaj huam sib luag Detectors. Txawm hais tias ob qho tib si yog tsim los txhim kho cov duab xoo hluav taws xob, muaj ntau qhov sib txawv ntawm ob lub thev naus laus zis.
Yuav kom nkag siab qhov txawv, cia pib nrog cov duab tsis sib haum. Duab Partthifiers yog Electro-kho cov khoom siv feem ntau siv nyob rau hauv teb ntawm radiology. Lawv txoj haujlwm tseem ceeb yog txhawm rau txhim kho cov duab xoo hluav taws xob, ua rau lawv pom meej dua thiab paub meej ntxiv. Tus ua haujlwm ua haujlwm ntawm cov duab ua kom muaj zog yog hloov X-duab duab rau cov teeb pom kev zoo, cov duab xoo hluav taws xob qub.
Ib qho tseem ceeb ntawm cov duab intensifier yog lub tswv yim phosphor, uas nqus cov xas photons thiab emits pom lub teeb photons. Cov photons no tau nrawm thiab tsom mus rau cov zis phosphor, tsim cov duab loj heev. Cov duab tshaj tawm no tuaj yeem ntes tau los ntawm lub koob yees duab lossis tso tawm ntawm tus saib xyuas rau cov hom kev kuaj mob. Duab Partthifiers muaj txiaj ntsig zoo heev thaum muab cov duab tiag tiag thiab yog qhov zoo rau cov txheej txheem uas xav tau kev yees duab tiag tiag, xws li fluoroscopy.
Tiaj tus vaj huam sib luag detectors (FPDs) tau dhau los ua lwm txoj hauv kev rau cov duab tsis sib haum. Tiaj tus vaj huam sib luag detectors yog cov khoom siv-xeev uas ntes cov duab xoo hluav taws xob ncaj qha thiab hloov lawv mus rau hauv cov cim digital. Tsis zoo li Duab Zog, FPDs tsis cia siab rau kev hloov X-Phot duab rau hauv pom lub teeb pom kev. Lawv tau siv cov array ntawm nyias-zaj duab xis transistors (TFTS) los hloov X-NPHOS Photo rau cov cim hluav taws xob.
Lub ntsiab kom zoo ntawm lub tiaj tus vaj huam sib luag soj ntsuam yog lub peev xwm los ntes cov kev daws teeb meem digital cov duab nrog kev txhim kho ntau yam. Cov teeb liab digital no tuaj yeem ua tiav ncaj qha thiab pom ntawm lub khoos phis tawm rau kev tsom xam sai. Tiaj tus vaj huam sib luag detectors kuj muab ib daim teb loj ntawm kev pom thiab kev nrhiav ntau dua, DQE) piv rau cov duab tsis sib haum, ua rau muaj cov duab zoo dua.
Tav tus vaj huam sib luag yeej cov neeg tuaj yeem muaj qhov tseem ceeb hauv kev hloov pauv thiab versatility. Lawv tuaj yeem yooj yim sib xyaw ua ke x-ray tshuab, hloov cov duab ua kom muaj zog yam tsis muaj kev hloov kho dav.
Qhov sib txawv ntawmXoo hluav taws xob Duab Pustifiersthiab tiaj tus vaj huam sib luag detectors dag nyob rau hauv lawv cov thev naus laus zis thev naus laus zis thiab ua haujlwm. Cov Duab Ua Kom Yooj Yim Yawg Ntxhia Xoo Hluav Taws Xob Los Ntawm Kev Hloov X-Pob xoo detection rau pom cov teeb pom kev zoo ncaj qha duab thiab hloov lawv mus rau hauv cov cim digital. Ob cov txuj ci muaj lawv qhov zoo thiab qhov tsis zoo, thiab xaiv ntawm lawv nyob ntawm cov kev ntsuam xyuas cov kev ntsuam xyuas, thiab theem ntawm cov duab xav tau. Ob daim duab hatictifiers thiab tiaj-detectures pab ua ntej ntawm cov duab xoo hluav taws xob thiab txhim kho cov neeg mob.
