Theimage intensifierakaberekwa muna 1950s uye chaiva chigadzirwa chikuru.Kuonekwa kwake kwakagumisa nhoroondo yemifananidzo yekrini.Yakaita kuti X-ray fluoroscopy dose ideredzwe zvikuru munguva iyoyo, kurerukirwa kwenyanzvi kwakavandudzwa zvikuru, uye murwere nenyanzvi vakagamuchira mwero mukuru wedziviriro.
Saizvozvowo, nekuvandudzwa kwekombiyuta, zvigadziridzo zvemufananidzo zvakasvika nhasi, uye zvishoma nezvishoma zvakapinda mukukwegura, uye kuguma kwekutsiviwa kwakarongwa kwenguva refu.Nekubudirira kweakasiyana siyana ane simba emifananidzo tekinoroji, mufananidzo wekuwedzera wekufungidzira tekinoroji inobviswa zvishoma nezvishoma.
Nhasi, ini handisi kuzokoshesa chiyeuchidzo chekusimbisa mufananidzo pano, asi kungoongorora kuti nei mufananidzo wekuwedzera wakabviswa nemunhu wese.Ndinofunga kuti pane zvikonzero zvishoma:
Kutanga: chimiro chekufungidzira idiki, uye zviri nyore kupotsa uye kusaziva.
Sezvinogona kuonekwa kubva pamufananidzo uri pasi apa, rutivi rworuboshwe mufananidzo wakaumbwa nekufungidzira kuwedzera kwechikamu chekudya chese, chinogona kungova nechikamu chechikamu chakaongororwa mune imwe furemu;rutivi rworudyi ndiyo yazvino hukuru-hukuru imaging, iyo inogona kuva neiyo yose Nzvimbo yose yekuongorora yegumbo rekudya inogona kuve yakanakira kutarisa uye kuongororwa.
Mumamiriro ezvinhu akajairwa, kana uchishandisa kufungidzira kwekusimudzira mutsauko, zvinodikanwa kuti urambe uchifambisa chinzvimbo chekusimudzira mumvuri, kutevedzera mafambiro eanosiyanisa ajenti, uye kuona-chaiyo-nguva yekutarisa, kuitira kuti utore zvirinani nzvimbo yeronda, asi kuongororwa neanokurumidza kusiyanisa mumiririri kuyerera mwero, zviri nyore kuti Chishandiso hachigone kuenderana nekufamba, saka hachigone kucherechedzwa.Semuenzaniso, mune esophagography, zviri nyore kuoneka chiitiko chekusiyanisa kuwedzera uye dislocation yemusiyano mumiririri.
Iyo diki yekufungidzira fomati yakave chikonzero chakakosha chekukura kushoma kwekuwedzera kwemufananidzo.Saka, zvinoita here kuita kuti mumvuri uve mukuru?Muchokwadi, inogona kuoneka kubva kumusimboti wekushanda wekuwedzera kwemumvuri kuti nekuwedzera kweiyo fomati yekufungidzira, vhoriyamu yemumvuri wese inowedzera zvakare inoshanduka zvakanyanya, uye pakupedzisira haigone kushandiswa mukubatana nemuchina wese, saka iyo ikozvino yakakura mumvuri kuwedzera inogona chete kusvika 12 inches, inowanzoshandiswa Iwo makuru ndiwo 7/9inch.
Chechipiri, zviri nyore kukanganiswa uye kukanganiswa, uye zviri nyore kupotsa uye kuongororwa zvisiri izvo.
Nekuda kweiyo misimboti yekushanda, mifananidzo intensifiers inotarisana nekukanganisa uye kukanganisa.Kukanganisa Kune marudzi maviri makuru ekutsveyamisa: imwe idenderedzwa yakaenzana geometric distortion;imwe yacho asymmetrical, inowanzonzi S-distortion.
Chikonzero chekukanganiswa kweiyo geometric ndechekuti kuratidzwa kwechifananidzo cheX-ray panzvimbo yakakomberedzwa kunoburitsa mufananidzo wakakura wechinhu chiri pandiro yekunopinda kumacheto echidzitiro chekupinza pane chepakati.Uku kukanganisa kune hukama neiyo geometry yechiratidziro chekuisa uye kusiyanisa kweiyo X-ray sosi.chinzvimbo-inotsamira, saka inonzi geometrical distortion.Lenzi ine kukanganiswa kwakashata inobhadhara zvishoma kune kukanganisa kwakanaka nekuda kwekukombama kweiyo skrini yekupinza, nekudaro ichidzikisa kukanganiswa kwese kwechifananidzo chinobuda, asi kukanganisa hakugone kudzivirirwa.
Imwe mhando yekukanganisa inodaidzwa kuti S-distortion, iyo inokonzerwa nechimiro cheS-chakaita mufananidzo wezvinhu rectilinear, chiitiko chinokonzerwa nekukanganisika kubva kuMagineti ePasi kana kurasika magineti kubva kune yakatenderedza midziyo.
Izvo chaizvo nekuda kwekukanganiswa uye kukanganisa (sezvinoratidzwa mumufananidzo uri pasi apa) iyo inopindira zvakanyanya nemigumisiro yekuongorora kuongororwa kwemifananidzo ye-X-ray, iyo inogona kutungamirira nyore nyore kuongororwa uye kukanganisa.
Chechitatu, kusiyana kwechifananidzo kwakaderera, izvo zviri nyore kupotsa uye kusaongororwa.
Parizvino, dhizaini yemhando yekufungidzira kweX-ray ndeye 14-bit kana 16-bit, nepo dhizaini yemhando yekusimbisa mifananidzo ingori gumi-bit.Mune mamwe mazwi, iyo ine simba renji yezvino mainstream dynamic imaging zvigadzirwa ka16 kana 32 nguva yefirimu.
Iyo dynamic range yakasiyana, uye mhedzisiro inoratidzwa mumufananidzo uri pazasi.Iyo ine simba renji kuruboshwe iri pachena yakaipisisa kupfuura iyo iri kurudyi, saka kunaka uye ruvara rwechifananidzo zvakasiyana kwazvo.
Mufananidzo wekuwedzera kwemumvuri unoratidzwa mumufananidzo uri pasi apa.Hurukuro hwemabhiti gumi huchave husina rubatsiro mukutarisa kwezvironda zvine misiyano midiki muhuwandu hwemifananidzo, kunyanya mune exudative uye diffuse imaging pathological shanduko sekutanga SARS mapapu shanduko.Izvo hazvigone kuongororwa nenzira kwayo, izvo zvinogona kutungamira nyore kupotsa kuongororwa uye kusaziva.
Tekinoroji iri kuchinja zuva rega rega, uye shanduko yechigadzirwa iri kuzunguza pasi.Image intensifiersvakapfuura nemumazuva avo ane mbiri uye vasvika kumagumo ehupenyu hwavo.Panofanira kunge paine mabhindauko akawanda mukurapa imaging diagnostic.Kurangarira zvakapfuura uye kutarisira ramangwana, chinhu chose chinozopedzisira chave nhoroondo.
Kana iwe uchifarira zvigadzirwa zvedu, unogamuchirwa kubvunza.
