Fasahar CR tana ɗaukar hotunan X-ray da allon hoto, tana motsa allon hoto da laser, tana canza siginar haske da allon hoto ke fitarwa zuwa sadarwa ta hanyar kayan aiki na musamman, sannan a ƙarshe tana sarrafawa da kuma ɗaukar hotunan ta amfani da kwamfuta. Ya bambanta da maganin radiation na gargajiya domin CR tana amfani da IP maimakon fim a matsayin mai ɗaukar hoto, don haka fasahar CR tana taka rawa a cikin tsarin ci gaban fasahar maganin radiation na zamani.
1.2 Daukar hoton kai tsaye (DR)
Akwai wasu bambance-bambance tsakanin daukar hoton X-ray kai tsaye da na'urorin X-ray na gargajiya. Da farko, hanyar daukar hoton fim mai saurin daukar hoto ana maye gurbinta da canza bayanan zuwa siginar da kwamfuta za ta iya gane ta hanyar na'urar gano bayanai. Na biyu, ta amfani da aikin tsarin kwamfuta don sarrafa hotunan dijital, dukkan tsarin aikin lantarki ne gaba daya, wanda ke ba da sauki ga bangaren lafiya.
Za a iya raba hoton rediyo mai layi zuwa nau'i uku gwargwadon nau'ikan na'urorin ganowa daban-daban da yake amfani da su. Hoton dijital kai tsaye, na'urar gano shi farantin silicon ne mara tsari, idan aka kwatanta da canjin makamashi kai tsaye DR. A ƙudurin sarari ya fi fa'ida; Don hoton dijital kai tsaye, na'urorin ganowa da ake amfani da su sune: cesium iodide, gadolinium oxide na sulfur, cesium iodide/Gadolinium oxide na sulfur + ruwan tabarau/fiber na gani +CCD/CMOS da cesium iodide/Gadolinium oxide na sulfur + CMOS; Mai ƙara girman hoto Tsarin daukar hoto na dijital X,
Ana amfani da na'urar gano CCD a yanzu sosai a tsarin dijital na gastrointestinal da kuma babban tsarin angiography.
2. Ci gaban manyan fasahar daukar hoton dijital ta likitanci
2.1 Ci gaban CR na baya-bayan nan
1) Inganta allon daukar hoto. Sabon kayan da aka yi amfani da shi a tsarin farantin daukar hoto yana rage yawan hasken da ke watsawa, kuma an inganta kaifin hoton da kuma ƙudurin cikakkun bayanai, don haka ingancin hoton ya inganta sosai.
2) Inganta yanayin duba bayanai. Ta amfani da fasahar duba layi maimakon fasahar duba bayanai ta hanyar amfani da CCD a matsayin mai tattara hotuna, a bayyane yake cewa lokacin duba bayanai ya ragu.
3) An ƙarfafa kuma an inganta manhajojin bayan sarrafawa. Tare da haɓaka fasahar kwamfuta, masana'antun da yawa sun gabatar da nau'ikan software daban-daban. Ta hanyar amfani da waɗannan manhajoji, wasu sassan hoton da ba su da kyau za a iya inganta su sosai, ko kuma a rage asarar cikakkun bayanai na hoto, don samun hoto mai haske.
4) CR na ci gaba da bunƙasa a cikin hanyar aikin asibiti kamar DR. Kamar yadda tsarin aikin DR ya rarraba, CR na iya shigar da mai karatu a cikin kowane ɗakin daukar hoto ko na'urar aiki; Kamar yadda DR ke samar da hoto ta atomatik, tsarin sake gina hoto da kuma duba laser ana kammala shi ta atomatik.
2.2 Ci gaban bincike na Fasaha ta DR
1) Ci gaba a fannin daukar hotunan dijital na silicon mara lu'ulu'u da kuma na'urorin gano bakin zaren selenium masu siffar amorphous. Babban canji yana faruwa ne a tsarin tsarin lu'ulu'u, a cewar bincike, allura da tsarin ginshiƙai na silicon mai siffar amorphous da selenium mai siffar amorphous na iya rage watsawar X-ray, ta yadda za a inganta kaifin da kuma kyawun hoton.
2) Ci gaba a fannin daukar hoto na dijital na na'urorin gano faifan CMOS. Layin layin fluorescent na na'urar gano faifan CM0S zai iya samar da layukan fluorescent da suka dace da hasken X-ray da ya faru, kuma ana kama siginar fluorescent ta hanyar guntu na CMOS sannan a ƙarshe a ƙara girmanta da sarrafa ta. Saboda haka, ƙudurin sarari na na'urar gano faifan M0S yana da girman 6.1LP/m, wanda shine na'urar gano faifan mafi girman ƙuduri. Duk da haka, saurin ɗaukar hoto mai jinkirin gaske na tsarin ya zama raunin na'urorin gano faifan CMOS.
3) Hoton dijital na CCD ya samu ci gaba. An inganta hoton CCD a cikin kayan aiki, tsari, da sarrafa hoto, ta hanyar sabon tsarin allura na kayan X-ray scintillator, haske mai yawa da madubi mai ƙarfi da haɗin kai mai ƙarfi na 100% na ƙwarewar hoton guntu na CCD, an inganta haske da ƙudurin hoto.
4) Amfani da DR a asibiti yana da fa'idodi masu yawa. Ƙarancin allurai, ƙarancin lalacewar radiation ga ma'aikatan lafiya da tsawaita tsawon lokacin aiki na na'urar duk fa'idodi ne na fasahar DR Imaging. Saboda haka, DR Imaging yana da fa'idodi a gwajin ƙirji, ƙashi da nono kuma ana amfani da shi sosai. Sauran rashin amfani sune tsadar farashi.
