Musiyano uripomufananidzo intensifiersuyeflat panel detectors.Mumunda wemifananidzo yezvokurapa, X-rays inoita basa rinokosha pakuongorora uye kurapa zvirwere zvakasiyana-siyana nekukuvara.Kufambira mberi mune tekinoroji kwakaita kuti pave neyakaomesesa X-ray mifananidzo yekutora mifananidzo.Zvitsva zviviri zvakadai mifananidzo intensifiers uye flat panel detectors.Kunyangwe ese ari maviri akagadzirirwa kusimudzira mifananidzo yeX-ray, pane misiyano yakakura pakati pehunyanzvi huviri.
Kuti tinzwisise musiyano, ngatitangei nemifananidzo intensifiers.Image intensifiers zvinhu zve electro-optical zvinowanzoshandiswa mumunda weradiology.Basa ravo guru nderekuwedzera mifananidzo yeX-ray, ichiita kuti iite seyakajeka uye yakadzama.Nheyo yekushanda yemufananidzo wekusimbisa ndeyekushandura X-ray mafotoni kuita mafotoni anooneka, achiwedzera kusimba kweiyo yekutanga X-ray mufananidzo.
Chinhu chakakosha cheiyo intensifier yemufananidzo ndiyo inopinza phosphor, iyo inotora X-ray mafotoni uye inoburitsa inooneka mafotoni.Aya mafotoni anokwidziridzwa uye anotariswa pane inobuda phosphor, ichigadzira mufananidzo wakakudzwa.Uyu mufananidzo wakakuriswa unogona kubva watorwa nekamera kana kuratidzwa pane chekutarisa nekuda kwekuongorora.Image intensifiers inoshanda chaizvo pakupa mifananidzo chaiyo-nguva uye yakanakira maitiro anoda chaiyo-nguva yekufungidzira, senge fluoroscopy.
Flat panel detectors (FPDs) yave imwe nzira yekuwedzera mifananidzo.Flat panel detectors zvinhu zvakasimba-nyika zvinotora zvakananga X-ray mifananidzo uye inoshandura kuva masaini edhijitari.Kusiyana nemifananidzo inosimbisa, maFPD haavimbe nekushandura maX-ray mafotoni kuita mafotoni anooneka.Vakashandisa akatevedzana matete-firimu transistors (TFTs) kushandura X-ray photon kuita zviratidzo zvemagetsi.
Mukana mukuru we flat panel detectors kugona kutora yakakwirira-resolution mifananidzo yedhijitari ine yakawedzera musiyano uye ine simba renji.Aya masaini edhijitari anogona kugadziriswa zvakananga uye kuratidzwa pakombuta kuti iongororwe nekukurumidza.Flat panel detectors inopawo nzvimbo yakakura yekuona uye yakakwirira yekuona quantum performance (DQE) kana ichienzaniswa neinosimbisa mifananidzo, zvichikonzera kuvandudzwa kwemhando yemifananidzo.
Flat panel detectors inopa zvakakosha zvakakosha mukushanduka uye kuita zvakasiyana.Iwo anogona kubatanidzwa zviri nyore mune aripo X-ray masisitimu, achitsiva echinyakare mifananidzo intensifiers pasina akawanda magadzirirwo.
Musiyano uripoX-ray image intensifiersuye flat panel detectors iri mune yavo yepasi tekinoroji uye mashandiro.Image intensifiers inokwidziridza mifananidzo yeX-ray nekushandura maX-ray mafotoni kuita mafotoni anooneka, ukuwo madhigirii epafurafura anobata zvakananga mifananidzo yeX-ray nekuashandura kuita masaini edhijitari.Matekiniki ese ane zvakanakira nekuipira, uye kusarudza pakati pawo zvinoenderana nezvinodiwa zvekufungidzira, kutariswa kwemitengo, uye nhanho yemhando yemufananidzo inodiwa.Zvese zviri zviviri zvinosimbisa mufananidzo uye flat-panel detectors zvinobatsira kufambisira mberi ndima yeX-ray imaging uye kunatsiridza kutarisirwa kwevarwere.
