DR cov khoom siv, uas yog, cov khoom siv hluav taws xob digital (Digital Radiography), yog cov khoom siv kho mob dav siv hauv kev kho mob niaj hnub.Nws tuaj yeem siv los kuaj cov kab mob hauv ntau qhov chaw thiab muab cov txiaj ntsig pom tseeb dua thiab raug dua.Cov qauv tseem ceeb ntawm DR ntaus ntawv muaj cov hauv qab no:
1. X-ray emission device: X-ray emission device yog ib qho tseem ceeb ntawm cov khoom siv DR.Nws yog tsim los ntawm X-ray raj, high voltage generator thiab lim thiab lwm yam. Lub X-ray emitting ntaus ntawv yuav tsim high-zog X-rays, thiab yuav kho thiab tswj raws li kev xav tau.Lub tshuab hluav taws xob high-voltage yog lub luag haujlwm los muab qhov tsim nyog voltage thiab tam sim no los tsim kom muaj lub zog X-ray.
2. Flat vaj huam sib luag ntes: Lwm qhov tseem ceeb ntawm DR cov cuab yeej yog lub tshuab ntes.Lub detector yog ib tug sensor uas hloov X-rays dhau los ntawm tib neeg cov ntaub so ntswg mus rau hauv hluav taws xob signals.Ib qho khoom siv ntes yog Flat Panel Detector (FPD), uas muaj cov duab rhiab heev, pob tshab conductive electrode thiab txheej txheej encapsulation.FPD tuaj yeem hloov X-ray lub zog rau hauv hluav taws xob, thiab xa mus rau lub khoos phis tawj rau kev ua thiab tso tawm los ntawm cov teeb liab hluav taws xob.
3. Kev tswj hluav taws xob: Lub tshuab hluav taws xob tswj hluav taws xob ntawm DR cov cuab yeej yog lub luag haujlwm rau kev tswj hwm thiab tswj kev ua haujlwm ntawm X-ray emitting li thiab detectors.Nws suav nrog lub khoos phis tawj, tswj vaj huam sib luag, digital teeb liab processor thiab cov duab ua software, thiab lwm yam. Lub khoos phis tawj yog lub chaw tswj hwm tseem ceeb ntawm DR cov cuab yeej, uas tuaj yeem tau txais, txheej txheem thiab khaws cov ntaub ntawv xa los ntawm tus ntes, thiab hloov mus rau hauv cov duab pom.
4. Tso saib thiab cov duab khaws cia: DR cov cuab yeej nthuav tawm cov duab tshwm sim rau cov kws kho mob thiab cov neeg mob los ntawm cov khoom zoo.Cov zaub feem ntau siv cov kua siv lead ua kua (LCD), muaj peev xwm ua kom pom cov duab siab thiab cov ncauj lus kom ntxaws.Tsis tas li ntawd, cov duab khaws cia cov duab tso cai rau cov duab tau txais kev cawmdim hauv cov qauv digital rau kev rov qab los, sib qhia thiab sib piv.
Nyob rau hauv tas li ntawd, lub ntsiab qauv ntawmDR cov khoom sivsuav nrog X-ray emission ntaus ntawv, lub vaj huam sib luag tiaj tus ntes, hluav taws xob tswj qhov system, tso saib thiab cov duab khaws cia.Cov khoom siv no ua haujlwm ua ke los ua kom DR cov khoom siv los tsim cov duab kho mob zoo thiab raug, muab kev kuaj mob kom meej thiab cov phiaj xwm kho mob.Nrog rau kev txhim kho txuas ntxiv ntawm thev naus laus zis, DR cov cuab yeej kuj tseem txhim kho thiab ua kom zoo dua los muab cov cuab yeej siv tau zoo thiab txhim khu kev qha rau kev kuaj mob.
