Umshini we-X-ray wedijithali yilokho esivame ukukubiza ngokuthi i-DR.Umshini we-X-ray ufakwe aumtshina wephaneli eyisicaba, futhi isithombe singabukwa ngqo kukhompuyutha.Ngabe isithombe esinjalo sedivayisi esilula?Siyini isimiso?Namuhla, ngizonithatha nonke ukuze niqonde
Okokuqala, kunezinhlobo ezintathu zezinto zokwakha zephaneli eyisicaba, i-cesium iodide, uhlobo lwe-amorphous selenium kanye nohlobo lwe-CCD.Ngezansi, sizobethula ngokulandelana:
I-Cesium iodide.Umgomo ovamile: Okokuqala guqula ama-X-reyi abe ukukhanya okubonakalayo ngokusebenzisa izinto eziphakathi nendawo ze-fluorescent, bese uguqula amasiginali okukhanya abonakalayo abe amasiginali kagesi ngokusebenzisa izakhi ze-photosensitive, futhi ekugcineni uguqule amasignali kagesi we-analog abe amasignali edijithali nge-A/D.
Ifomu le-amorphous selenium.Isimiso esivamile: Ama-semiconductive e-photoconductive aguqula ama-photon e-X-ray atholiwe abe amashaji kagesi, abe esefundwa futhi afakwe kudijithali ngoxhaxha lwama-transistors amafilimu amancane.
Isimiso esijwayelekile sohlobo lwe-CCD: Isikrini esithuthukisiwe sisetshenziswa njengendlela yokusebenzisana ye-X-ray, futhi i-CCD iyengezwa ukwenza isithombe se-X ray sibe yidijithali.
I-Weifang Newheek Electronic Technology Co., Ltd. ingumkhiqizi wemikhiqizo ye-X-ray.Uma ufuna ukwazi okwengeziwe ngemishini ye-X-ray kanyeama-detectors angama-flat-panel, wamukelekile ukuxhumana nathi.Ucingo: +8617616362243!
