Indirect detectors muaj ib txheej ntawm scintillator khoom, feem ntau yog ib qho gadolinium oxysulfide los yog cesium iodide , uas converts x-rays rau hauv lub teeb.
Ib yam li ntawd, lub vaj huam sib luag tiaj tiaj 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 mus rau hauv cov ntaub ntawv hluav taws xob uas lub khoos phis tawj tuaj yeem tso tawm ua cov duab zoo digital.
Ib yam li ntawd, dab tsi yog qhov ntsuas digital? Digital radiography yog ib daim ntawv ntawm radiography uas siv x-ray-sensitive daim hlau los ncaj qha mus ntes cov ntaub ntawv thaum lub sij hawm soj ntsuam tus neeg mob, tam sim ntawd hloov nws mus rau lub computer system yam tsis tas siv lub intermediate cassette. Hloov X-ray zaj duab xis, digital radiography siv a digital duab capture ntaus ntawv.
Tom qab ntawd, lo lus nug yog, dab tsi yog cov npe ntawm ob hom kev hloov pauv tsis ncaj nraim hauv vaj huam sib luag ntes?
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.
Dab tsi yog TFT hauv hluav taws xob?
Ib tug nyias-film transistor ( TFT ) yog ib hom tshwj xeeb ntawm cov hlau-oxide-semiconductor field-effect transistor (MOSFET) ua los ntawm kev tso cov yeeb yaj kiab nyias ntawm cov txheej txheem semiconductor nrog rau cov txheej txheem dielectric thiab cov hlau sib tiv tauj dhau ntawm kev txhawb nqa (tab sis tsis ua) substrate.
