X-ray imaging chinhu chakakosha chekuongorora mukurapa, chinobvumira vashandi vehutano kuona uye kuongorora mamiriro akasiyana ekurapa.Iyo image intensifier, chikamu chakakosha che X-ray machine, inoita basa rakakosha mukusimudzira kunaka nekujeka kwemifananidzo iyi.Muchikamu chino, tichaongorora zviyero zveX-ray image intensifiersuye kuti vanoita sei mukufambisira mberi kwehunyanzvi hwekufungidzira hwekurapa.
X-ray image intensifiers midziyo ine hunyanzvi inoshandura mwaranzi yeX-ray kuita mufananidzo unooneka.Aya anowedzera ane akati wandei zvinhu, zvinosanganisira yekupinda phosphor, photocathode, electron optics, uye inobuda phosphor.Iyo phosphor inopinza inoburitswa kune X-ray mwaranzi uye inoburitsa mafotoni akajeka, ayo anobva ashandurwa kuita maerekitironi nephotocathode.Maelectron optics anokudza uye anonangisa maerekitironi aya, achiatungamira kune inobuda phosphor, kwaanoshandurwa achidzokera kuita mwenje unooneka, zvichikonzera mufananidzo wakawedzerwa.
Chimwe chezviyero zvakakosha zveX-ray image intensifiers inzvimbo yekupinda.Iyi dimension inosarudza saizi yeX-ray radiation field inogona kutorwa nekushandurwa kuita mufananidzo.Kazhinji, ukuru hwenzvimbo yekupinza inotangira kubva ku15 kusvika ku40 centimita muhupamhi, zvichibvumira pekugara kwezvikamu zvakasiyana-siyana zvemuviri uye zvekufungidzira zvinodiwa.Izvo zvakakosha kuti nzvimbo yekupinza ienderane nezvinodiwa zvekufungidzira kuti ive nechokwadi chechokwadi uye chakazara chekuongorora.
Pamusoro pezvo, ukobvu hweiyo yekuisa phosphor layer ndiyo imwe nhanho yakakosha yeX-ray image intensifiers.Ukobvu hweiyi danga hunotaridza kugona kweX-ray photons shanduko kuita mwenje unooneka.Yakaonda yekupinza phosphor layers inowanzopa yakakwirira spatial resolution, ichigonesa kuona uye kuona kwezvimiro zvidiki mukati memuviri.Nekudaro, akakora ekuisa phosphor akaturikidzana anowanzo kufarirwa mumamiriro ezvinhu apo mamwe radiation senitivity inodiwa.
Uyezve, saizi uye chimiro cheiyo X-ray mifananidzo inowedzera inoita basa rakakosha mukubatanidzwa kwavo neX-ray masisitimu uye kunyaradza kwevarwere.Zviyero izvi zvinoda kuvandudzwa kuti zvive nyore kuiswa uye kurongeka panguva yebvunzo.Madiki uye akareruka mufananidzo anosimbisa anobvumira kuchinjika kukuru uye kufambisa, kubatsira vashandi vehutano mukutora mifananidzo inodiwa zvinobudirira.Uyezve, iyo ergonomics yechimiro inobatsira kunyaradzo yevarwere, kuderedza kufamba kusingakoshi uye kusagadzikana kunogona kuitika panguva yeX-ray maitiro.
Kunze kwehukuru hwemuviri, mhando yemufananidzo inogadzirwa neX-ray image intensifiers yakakosha mukuongorora.Kugadziriswa, kusiyanisa, uye kupenya kwemifananidzo yakasimbiswa zvakanyanya kunokanganisa huchokwadi uye kushanda kwechirwere ichi.Kufambira mberi mune tekinoroji yekusimbisa tekinoroji kwatungamira mukuvandudzwa kwemadhijitari, senge flat-panel detectors, iyo inopa yakakwirira spatial resolution uye ine simba renji kana ichienzaniswa neyechinyakare intensifiers.Aya madhijitari edhijitari akasandura kufungidzira kweX-ray, zvichibvumira kukwidziridzwa kwemhando yemifananidzo uye nekuvandudza kuvimba kwekuongorora.
Mukupedzisa, X-ray image intensifiers zvinhu zvakakosha zvekurapa imaging tekinoroji.Zviyero zvezvisimbisi izvi, zvinosanganisira nzvimbo yekupinda, ukobvu hweiyo phosphor layer yekuisa, uye saizi uye chimiro, zvinhu zvakakosha zvinopesvedzera kunaka uye kushanda kwemifananidzo yeX-ray.Pamusoro pezvo, kufambira mberi mune tekinoroji kwaunza madhijitari edhijitari anopa mhando yepamusoro yemifananidzo.Sezvo kufungidzira kwezvokurapa kuri kuramba kuchishanduka, zviyero izvi zvichaita basa rinokosha mukusundira miganhu yehutano hwekuongorora, zvinozotungamirira kune hutano hwakanaka hwevarwere uye migumisiro.
