Pankhani yojambula zithunzi zachipatala, kulondola ndi kulondola n'kofunika kwambiri. Ma X-ray collimators amachita gawo lofunika kwambiri pakuwonetsetsa kuti kuwala kwa radiation kwalunjika bwino pamalo omwe mukufuna, kuchepetsa kuwonekera kwa minofu yozungulira. Pamene ukadaulo ukupitilira, chitukuko cha ma X-ray collimators odziyimira pawokha chasintha momwe akatswiri a radiology ndi akatswiri amachitira njira zojambulira zithunzi. Nkhaniyi ikufotokoza kusiyana pakati pa ma automated ndi manual collimators, kuwonetsa ubwino ndi zofooka za chilichonse.
Kodi X-ray collimator ndi chiyani?
Ma X-ray collimatorsNdi zipangizo zomwe zimayikidwa pa makina a X-ray zomwe zimathandiza kupanga ndi kuchepetsa kuwala kwa X-ray. Mwa kuwongolera kukula ndi mawonekedwe a kuwalako, ma collimator amachepetsa kuwala kosafunikira kwa odwala ndi ogwira ntchito zachipatala. Amathandizanso kuti chithunzi chikhale bwino mwa kuchepetsa kuwala komwe kumafalikira, komwe kungabise tsatanetsatane wa matenda.
Collimator yamanja: njira yachikhalidwe
Manual collimators akhala akugwiritsidwa ntchito mu radiology kwa zaka zambiri. Zipangizozi zimafuna kuti wogwiritsa ntchito asinthe makonzedwe a collimator pamanja asanayesedwe X-ray iliyonse. Katswiri ayenera kugwirizanitsa collimator ndi malo omwe akufunidwa, nthawi zambiri kuwonetsa malo omwe akuwonekera ndi kuwala. Ngakhale manual collimators ndi osavuta komanso otsika mtengo, ali ndi zoletsa zina.
Chimodzi mwa zovuta zazikulu za ma collimator amanja ndi kuthekera kwa kulakwitsa kwa anthu. Kusintha kwa njira yogwiritsira ntchito kungayambitse kusakhazikika kwa kuwala kwa dzuwa, zomwe zingayambitse wodwala kuwonekera mopitirira muyeso kapena mochepa. Kuphatikiza apo, kusintha kwa dzanja kungakhale kotenga nthawi, makamaka m'malo otanganidwa azachipatala komwe kugwira ntchito bwino ndikofunikira.
Ma X-ray collimators odziyimira pawokha: tsogolo la kujambula zithunzi
Ma X-ray collimator odziyimira okha akuyimira kupita patsogolo kwakukulu muukadaulo wojambulira zithunzi. Zipangizozi zimagwiritsa ntchito masensa ndi ma algorithms apamwamba kuti zisinthe zokha makonda a collimation kutengera kapangidwe kake ka chithunzi chomwe chikujambulidwa. Mwa kuphatikiza ndi pulogalamu ya makina a X-ray, autocollimator imatha kuzindikira kukula ndi mawonekedwe a dera lomwe mukufuna ndikusintha kuwala kwake moyenerera.
Chimodzi mwa zabwino kwambiri za ma autocollimator ndi kuthekera kwawo kupititsa patsogolo chitetezo cha odwala. Mwa kuchepetsa kukhudzana ndi kuwala kosafunikira, zipangizozi zimathandiza kuteteza odwala ku zotsatira za kuwala kwa nthawi yayitali. Kuphatikiza apo, ma autocollimator amatha kukonza bwino chithunzi mwa kuonetsetsa kuti kuwalako kuli bwino, motero kuchepetsa mwayi woti chithunzicho chibwererenso chifukwa cha khalidwe loipa la chithunzi.
Kusiyana kwakukulu pakati pa manual collimators ndi autocollimators
Ntchito: Ma collimator opangidwa ndi manja amafuna kusintha kwa manja ndi akatswiri, pomwe ma collimator opangidwa ndi manja amagwira ntchito kutengera magawo omwe akonzedweratu komanso kusanthula deta nthawi yeniyeni.
Kulondola: Ma Autocollimator amapereka kulondola kwakukulu pakulinganiza kwa beam, kuchepetsa chiopsezo cha zolakwika za anthu zokhudzana ndi kusintha kwamanja.
Kuchita bwino: Kapangidwe ka makina ojambulira zithunzi amenewa kamachepetsa nthawi yokhazikitsa zithunzi, zomwe zimathandiza kwambiri m'madipatimenti opanga zithunzi zambiri.
MtengoNgakhale mtengo woyamba wa autocollimator ukhoza kukhala wokwera, uli ndi kuthekera kosunga ndalama pakapita nthawi pokonza zotsatira za odwala ndikuchepetsa kuchuluka kwa mayeso obwerezabwereza.
Maphunziro: Ma collimator opangidwa ndi manja amafuna akatswiri kuti amvetsetse bwino njira zolumikizirana, pomwe ma collimator opangidwa ndi makina okha amatha kupangitsa kuti maphunziro akhale osavuta komanso kuti ntchito ikhale yosavuta.
Powombetsa mkota
Pamene gawo la radiology likupitirira kukula, kugwiritsa ntchitoma collimator a X-ray odziyimira pawokhazikuoneka kuti zikuwonjezeka. Ngakhale kuti makina opangira zinthu pogwiritsa ntchito manja akhala akuthandiza makampaniwa kwa zaka zambiri, ubwino wa makina opangira zinthu (kulondola kwambiri, chitetezo cha odwala, komanso kugwira ntchito bwino) zimapangitsa kuti zikhale zofunikira kwambiri kuziphatikiza muzojambula zamakono. Kumvetsetsa kusiyana pakati pa mitundu iwiriyi ya makina opangira zinthu ndikofunikira kwambiri kwa akatswiri azachipatala pamene akuyesetsa kupereka chisamaliro chabwino kwambiri kwa odwala awo.
