Ob hom indirect : CCD thiab TFT ob leeg yuav tsum tau xray hloov dua siab tshiab rau lub teeb thiab ces mus rau hluav taws xob teeb liab nrog photodiode txheej.
Kuj tseem yuav paub yog, lub npe cassette raws li digital imaging system yog dab tsi?
Kev suav radiography yog ib daim ntawv tsis ncaj ntawm cov duab digital siv a cassette system zoo ib yam li cov tsos thiab muaj nuj nqi rau cov uas siv nyob rau hauv cov pa zaj duab xis-screen radiography (Fig. 2-37).
Qhov thib ob, qhov kev kuaj hniav tsis ncaj qha yog dab tsi? Txoj kev ncaj qha siv lub tshuab hluav taws xob tso rau hauv lub qhov ncauj los sau cov duab. Cov tsis ncaj txheej txheem siv ib X-ray zaj duab xis scanner saib tsoos kev kho hniav X-rays raws li cov duab digital. Semi- tsis ncaj cov txheej txheem digital muab cov sensor thiab scanner los hloov kev kho hniav X-rays rau hauv cov yeeb yaj kiab digital.
Tsis tas li lo lus nug yog, qhov txawv ntawm qhov kev hloov pauv digital tsis ncaj ncees thiab kev hloov pauv ncaj qha yog dab tsi?
Direct- hloov dua siab tshiab detectors muaj ib tug x-ray photoconductor, xws li amorphous selenium, uas converts x-ray photons mus rau hauv ib tug hluav taws xob nqi ncaj qha, tsis muaj theem nrab. Tsis ncaj - hloov dua siab tshiab cov khoom siv muaj lub tshuab scintillator uas thawj zaug hloov x rays rau hauv lub teeb pom kev.
Lub vaj huam sib luag ntes ua haujlwm li cas?
Kho mob Flat Vaj Huam Sib Luag Detectors . Varex's X-ray flat panel detectors rau digital radiography ua haujlwm los ntawm kev hloov cov X-rays uas tawm tsam nws qhov chaw rau hauv lub teeb, thiab tom qab ntawd tig lub teeb rau hauv cov ntaub ntawv hluav taws xob uas lub computer ua tau tso saib ua cov duab zoo digital.
