1. Ci gaban fasahar hoto na yau da kullun
1.1Radiyon Kwamfuta (CR)
Fasahar CR tana nadar haskoki na X-ray da allon hoto, tana burge allon hoton da na’urar lesar, tana mai da siginar hasken da allon hoton ke fitarwa zuwa sadarwa ta hanyar kayan aiki na musamman, sannan a karshe ana aiwatar da hotuna da taimakon kwamfuta. Ya bambanta da maganin radiation na gargajiya a cikin cewa CR yana 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 Radiyon Kai tsaye (DR)
Akwai wasu bambance-bambance tsakanin daukar hoto na X-ray kai tsaye da na'urorin X-ray na gargajiya. Da farko, ana maye gurbin hanyar daukar hotuna ta hanyar canza bayanai zuwa siginar da kwamfuta za ta iya gane ta ta hanyar ganowa. Abu na biyu, ta yin amfani da aikin tsarin kwamfuta don aiwatar da hotuna na dijital, dukkanin tsari shine cikakken aikin lantarki, wanda ke ba da dacewa ga bangaren likita.
Za'a iya raba radiyon layin layi kusan zuwa nau'i uku bisa ga nau'ikan gano abubuwan da yake amfani da su. Hoto na dijital kai tsaye, mai gano sa shine farantin silicon amorphous, idan aka kwatanta da canjin makamashi kai tsaye DR A cikin ƙudurin sararin samaniya ya fi fa'ida; Don hotunan dijital kai tsaye, masu gano abubuwan da aka saba amfani da su sune: cesium iodide, gadolinium oxide na sulfur, cesium iodide/Gadolinium oxide na sulfur + ruwan tabarau / fiber fiber + CCD/CMOS da cesium iodide/Gadolinium oxide na sulfur + CMOS; Tsarin ɗorawa na hoto Digital X tsarin daukar hoto,
Ana amfani da mai gano CCD a yanzu a cikin tsarin gastrointestinal na dijital da babban tsarin angiography
2. Haɓaka haɓakar manyan fasahar fasahar hoto na likitanci
2.1 Sabon ci gaban CR
1) Inganta allon hoto. Sabbin kayan da aka yi amfani da su a cikin tsarin farantin hoto yana rage girman yanayin watsawa mai haske, kuma an inganta hoton hoto da ƙuduri dalla-dalla, don haka ingancin hoton ya inganta sosai.
2) Inganta yanayin dubawa. Yin amfani da fasahar sikanin layi maimakon fasahar binciken tabo mai tashi da amfani da CCD a matsayin mai tattara hoto, ba shakka an gajarta lokacin dubawa.
3) Ana ƙarfafa software da haɓakawa bayan sarrafawa. Tare da haɓaka fasahar kwamfuta, masana'antun da yawa sun ƙaddamar da nau'ikan software iri-iri. Ta hanyar amfani da waɗannan software, ana iya inganta wasu wuraren da ba su da kamala sosai, ko kuma a rage asarar dalla-dalla na hoto, ta yadda za a sami hoto mai haske.
4) CR ya ci gaba da haɓakawa a cikin jagorancin aikin aikin asibiti kamar DR. Hakazalika da tsarin aiki na DR, CR na iya shigar da mai karatu a cikin kowane ɗakin rediyo ko na'ura mai kwakwalwa; Hakazalika da tsararrun hoto ta atomatik ta DR, ana kammala aikin sake gina hoto da duban laser ta atomatik.
2.2 Ci gaban bincike na Fasahar DR
1) Ci gaba a cikin hoto na dijital na siliki maras-crystal da amorphous selenium flat panel detectors. Babban canji yana faruwa a cikin tsarin tsarin crystal, bisa ga bincike, allura da tsarin columnar na silicon amorphous da amorphous selenium na iya rage watsawar X-ray, don haka an inganta kaifi da tsabta na hoton.
2) Ci gaban dijital hoto na CMOS flat panel detectors. Layin layin mai kyalli na CM0S flat detector na iya samar da layukan kyalli masu dacewa da abin da ya faru na X-ray beam, kuma siginar mai kyalli yana kama guntu na CMOS kuma a ƙarshe ya ƙara girma kuma ana sarrafa shi. Saboda haka, ƙudurin sararin samaniya na mai gano shirin M0S ya kai 6.1LP/m, wanda shine mai ganowa tare da mafi girman ƙuduri. Koyaya, saurin saurin hoto na tsarin ya zama rauni na na'urorin gano fatun CMOS.
3) CCD dijital hoto ya samu ci gaba. An inganta hoton CCD a cikin kayan, tsari, da sarrafa hoto, mu ta hanyar sabon tsarin allurar da aka gabatar na kayan scintillator na X-ray, babban haske da babban madubin haɗin gani na gani da kuma cika ƙimar 100% CCD guntu hoton hankali, tsabtar hoto. kuma an inganta ƙuduri.
4) Aikace-aikacen asibiti na DR yana da fa'ida mai fa'ida. Karancin kashi, ƙarancin lahani ga ma'aikatan kiwon lafiya da tsawaita rayuwar na'urar duk fa'idodin fasahar DR Imaging ne. Saboda haka, DR Imaging yana da fa'ida a cikin ƙirji, ƙashi da gwajin ƙirjin kuma ana amfani dashi ko'ina. Sauran rashin amfani su ne in mun gwada da babban farashi.
3. Ƙwararren fasaha na fasaha na dijital na likita - hoton kwayoyin halitta
Hoto na kwayoyin halitta shine amfani da hanyoyin hoto don fahimtar wasu kwayoyin halitta a cikin nama, salon salula da kuma matakin subcellular, wanda zai iya nuna canje-canje a matakin kwayoyin a cikin yanayin rayuwa.
