Kana zvasvika pakufungidzira kwekurapa, tekinoroji yeX-ray chishandiso chakakosha chinogona kupa ruzivo rwakakosha rwekuongorora.X-ray michina ine akati wandei zvinhu, uye chinhu chimwe chakakosha ndichoX-ray grid.Iyo X-ray grid inoshandiswa kukwidziridza mhando yemufananidzo nekudzikisa kupararira kwemwaranzi uye kugadzirisa mufananidzo musiyano.Kusarudza iyo chaiyo X-ray grid yakoX-ray muchinakwakakosha pakuona kwakaringana uye kwakajeka mhedzisiro yekufungidzira.Muchikamu chino, tichakurukura zvinhu zvekufunga nezvazvo pakusarudza X-ray grid yemuchina wako weX-ray.
Tisati tapinda muchirongwa chekusarudza, ngatinzwisise izvo zvekutanga zve X-ray grid.Giridhi yeX-ray mudziyo une mitsetse yakatetepa yelead inochinjana neradiolucent material.Basa rekutanga regridi nderekutora mwaranzi yekuparadzira inobuda kana X-ray mafotoni achibatana nemuviri wemurwere.Scatter radiation inogona kuderedza zvakanyanya kunaka kwemufananidzo nekugadzira yakasviba kumashure inozivikanwa se "grid mitsara."Nekutora mwenje yekuparadzira, maX-ray grid anobatsira kuwedzera musiyano wemifananidzo, zvichikonzera kupinza mifananidzo.
Chinhu chinonyanya kukosha chekufunga pakusarudza X-ray grid ndiyo chiyero chayo.Girishi reshiyo inoreva kureba kwemitsara inotungamira zvichienzaniswa nenhambwe iri pakati pawo.Mareshiyo egridi anonyanyozivikanwa ndeaya 6:1, 8:1, 10:1, uye 12:1.Yepamusoro gidhi reshiyo inopa zvirinani kuparadzira radiation absorption asi inoda yakakwira X-ray chubhu tekiniki zvinhu.Kazhinji, 10: 1 kana 12: 1 grid reshiyo yakanaka kune general radiography, sezvo ichinyatso bvisa kuparadzira radiation pasina kuwedzera zvakanyanya dosi yevarwere.
Chimwe chinhu chakakosha ndeye grid frequency, inomiririra huwandu hwemitsetse ye lead pa inch kana centimita.Yepamusoro grid frequency inokonzeresa madiki uye matete e lead mitsetse, inosimudzira mufananidzo asi ichiwedzera mutengo weX-ray grid.Grid frequency ye103 mitsetse painji kana 40 mitsetse pacentimita inowanzoshandiswa paruzhinji rweradiography.Nekudaro, mafambisirwo emagetsi epamusoro, akadai semitsetse 178 painji kana mitsara makumi manomwe pacentimita, inokurudzirwa kune zvehunyanzvi zvekufungidzira maapplication anoda emhando yepamusoro yemufananidzo.
Pamusoro peiyo grid reshiyo uye frequency, iyo grid zvinhu zvakakoshawo.Zvinhu zvakasiyana-siyana, zvakaita sealuminium, kabhoni fiber, uye mahybrid grids, anoshandiswa mukugadzira X-ray grid.Aluminium grids ndiwo anonyanya kushandiswa nekuda kwekudhura-kushanda uye kugona kunyura kwakanaka.Nekudaro, ivo vanowanzoremerwa uye vanogona kukonzera kukanganisa kwemufananidzo kana isina kunyatsoenderana neX-ray danda.Carbon faibha grids akareruka uye anopa zvakanakisa kunyura zvivakwa, asi zvinodhura.Hybrid grids inosanganisa mabhenefiti earuminiyamu uye kabhoni fiber grids, ichipa chiyero chakanaka pakati pemutengo uye kuita.
Izvo zvakakoshawo kuti titarise iyo grid's focal range, iyo inoreva kune huwandu hweX-ray chubhu-kusvika-gridhi madaro mukati umo gidhi rinoita zvakakwana.Michina yeX-ray yakasiyana ine zvinosiyana zvinodikanwa zvefocal range, uye kusarudza gidhi rinoenderana nemadimikira emuchina wako kwakakosha.Kushandisa gidhi kunze kweyakakurudzirwa kutariswa kunogona kukonzera suboptimal mufananidzo mhando uye kuwedzera murwere dosi.
Chekupedzisira, saizi yegridi inofanirwa kuenderana nehukuru hwe X-ray yemuchina wekufungidzira munda.Kushandisa gidhi idiki zvakanyanya kunogona kutungamirira kune grid cutoff, uko mipendero yegridi inovharira X-ray danda, zvichikonzera kushata kwemufananidzo.Kune rumwe rutivi, girasi rakanyanya kukura rinogona kusakwana zvakanaka kana kuwedzera chirwere chemurwere zvisina kufanira.
Mukupedzisa, kusarudza zvakanakaX-ray gridyemuchina wako weX-ray wakakosha kuti uwane mibairo yemhando yepamusoro yekufungidzira.Zvinhu zvakadai segridi reshiyo, frequency, zvinhu, focal range, uye saizi zvinofanirwa kutariswa kuti ive nechokwadi chekushanda kwakakwana.Kubvunzana neX-ray midziyovagadziri kana nyanzvi dzeradiology dzinogona kupa nhungamiro yakakosha pakusarudza iyo yakakodzera X-ray grid kune yako chaiyo yekufungidzira zvaunoda.
