Tiaj tus txiv huam sib luag detectors(FPDs) tau hloov kho lub teb ntawm kev kho mob kev ua haujlwm, muab cov duab zoo tshaj plaws thiab ua haujlwm piv rau kev ua kom ntsuas thev naus laus zis. Cov ntsuas no tau faib ua haujlwm raws li cov ntaub ntawv siv hauv lawv cov ntaub ntawv, nrog cov kws ntes digital (DR)
DR TAV VAJ HUAM SIB LUAG NTESyog categorized raws li hom ntes cov khoom, nrog ob txoj kev faib tawm tseem ceeb yog ncaj qha thiab cov ntsuas kev ncaj ncees. Kev siv cov ntaub ntawv drectors ncaj qha siv txheej txheej txheej txheej, xws li Amorphou Selenium, txhawm rau kho cov nqi hluav taws xob xoo hluav taws xob. Txoj kev hloov kho hloov dua siab tshiab no tau ua rau cov kev daws teeb meem siab thiab cov duab zoo nkauj, ua rau cov qauv siv detectors ncaj qha-haum rau kev ntes cov ntsiab lus zoo anatomical zoo.
Ntawm qhov tod tes, indirec drectors tau ua haujlwm rau cov khoom siv scintillator, kom hloov cov x-eodide lossis gadolinium rhots rau pom lub teeb, uas yog tom qab ntawd pom los ntawm ib qho kev pom ntawm photoDies. Thaum lub sij hawm tsis ncaj yuav qhia qee qib ntawm lub teeb tawg mus rau xoo hluav taws xob, ua rau muaj kev xav tau qis dua rau cov neeg mob.
Tsis pub dhau ntawm qeb ntawm indirecect drectors, muaj ntau yam txawv xws li amorphous silicon thiab amorphoud detectors. Amorphous silicon detectors yog paub rau lawv cov nqi-ua tau zoo thiab ua rau lawv xaiv nrov rau ntau cov kev siv duab. Ntawm qhov tod tes, amorphous selenium detectors yog muaj nuj nqis rau lawv cov siab detectionum efficiency (d •
Ntxiv rau cov khoom siv hauv cov ntaub ntawv, Dr Tiaj Tus Vaj Huam Sib Luag Detectors kuj tseem tuaj yeem sib txawv raws lawv qhov loj me, daws, thiab kev sib xyaw nrog cov tshuab yees duab. Cov cuab yeej loj tshaj plaws yog qhov haum rau ntes cov duab ntawm lub hauv siab, plab, thiab extremities, thaum lub sij hawm me me, thaum muaj cov txheej txheem kws kho mob tshwj xeeb xws li kev kho hniav radiariography.
Kev faib tawm ntawm DR tiaj tus vaj huam sib luag detectors ua si tau lub luag haujlwm tseem ceeb hauv kev txiav txim siab lawv cov kev xav paub txog kev ua haujlwm thiab cov yam ntxwv ua tau zoo.
