Pankhani yojambula zithunzi zachipatala, machubu a X-ray ndi ma CT scanner ndi ukadaulo waukulu womwe wasintha momwe matenda amachitikira. Ngakhale kuti zipangizo zonsezi zimagwiritsa ntchito ma X-ray kuti zione kapangidwe ka mkati mwa thupi la munthu, zimagwira ntchito mosiyana ndipo zimagwiritsidwa ntchito mosiyana. Kumvetsetsa kusiyana pakati pa machubu a X-ray ndi ma CT scanner ndikofunikira kwa ogwira ntchito zachipatala komanso odwala chifukwa zimakhudza kusankha kwawo ukadaulo woyenera wojambulira zithunzi zomwe zikugwirizana ndi zosowa zawo zachipatala.
Machubu a X-ray: Zoyambira
An Chubu cha X-rayndi chipangizo chomwe chimapanga ma X-ray pofulumizitsa ma elekitironi ndikuwatsogolera ku chinthu chomwe akufuna, chomwe nthawi zambiri chimapangidwa ndi tungsten. Ma elekitironi amphamvu awa akagundana ndi chinthucho, amapanga ma X-ray omwe amatha kulowa m'thupi ndikupanga chithunzi pa filimu kapena chowunikira digito. Kujambula kwachikhalidwe kwa X-ray kumagwiritsidwa ntchito makamaka pofufuza mafupa, kuzindikira kusweka kwa mafupa, ndikupeza matenda monga chibayo kapena zotupa pachifuwa.
Ubwino waukulu wa machubu a X-ray ndi liwiro lawo komanso kugwira ntchito bwino. Kuyeza kwa X-ray wamba kumatenga mphindi zochepa zokha kuti kumalizidwe, zomwe zimapangitsa kuti zikhale zoyenera pazochitika zadzidzidzi. Kuphatikiza apo, makina a X-ray nthawi zambiri amapezeka mosavuta komanso otsika mtengo kuposa ma CT scanner, zomwe zimapangitsa kuti akhale chida chodziwika bwino chojambulira zithunzi m'zipatala zambiri.
Ma CT scanners: sitepe yopita patsogolo
Koma makina ojambulira zithunzi a computed tomography (CT) apititsa patsogolo ukadaulo wojambulira zithunzi. Makina ojambulira zithunzi a CT amagwiritsa ntchito chubu chozungulira cha X-ray kuti ajambule zithunzi zambiri kuchokera mbali zosiyanasiyana za thupi. Kenako zithunzizi zimakonzedwa ndi kompyuta kuti zipange zidutswa za thupi, zomwe zimakupatsani chithunzi chatsatanetsatane cha kapangidwe ka mkati kuposa zithunzi za X-ray zachikhalidwe.
Tsatanetsatane wowonjezereka womwe umaperekedwa ndi ma CT scan ndi wothandiza kwambiri pozindikira matenda ovuta, monga kuvulala kwamkati, khansa, ndi matenda omwe amakhudza minofu yofewa. Ma CT scan amatha kuwulula zambiri zokhudza ziwalo, mitsempha yamagazi, komanso zotupa zomwe sizingawonekere pa ma X-ray wamba. Komabe, kuwonjezeka kumeneku kwatsatanetsatane kumabwera ndi mtengo; ma CT scan nthawi zambiri amakhala ndi kuwala kwambiri kuposa ma X-ray achikhalidwe.
Kusiyana kwakukulu mu kufotokoza
Ubwino wa chithunzi ndi tsatanetsatane: Kusiyana kwakukulu pakati pa machubu a X-ray ndi ma CT scanner ndi kuchuluka kwa tsatanetsatane wa zithunzi zomwe amapanga. Ma X-ray amapereka mawonekedwe amitundu iwiri, pomwe ma CT scan amapereka zithunzi zamitundu itatu zomwe zitha kumangidwanso m'magawo osiyanasiyana, zomwe zimathandiza kuwunika bwino kwambiri malo omwe akufunidwa.
Kuwonekera kwa kuwala kwa dzuwaMonga tanenera kale, ma CT scan nthawi zambiri amaika odwala pamlingo wapamwamba wa radiation kuposa ma X-ray wamba. Izi ndizofunikira kwambiri poganizira zoopsa ndi zabwino za njira iliyonse yojambulira zithunzi, makamaka kwa anthu omwe ali pachiwopsezo monga ana kapena odwala omwe amafunikira ma scan angapo.
Zizindikiro zogwiritsira ntchitoMachubu a X-ray nthawi zambiri amagwiritsidwa ntchito poyesa zinthu zosavuta, monga kuyang'ana mafupa osweka kapena matenda. Mosiyana ndi zimenezi, ma CT scanner ndi oyenera kwambiri pamavuto ovuta kwambiri ozindikira matenda, monga kuwunika ululu wa m'mimba, kuzindikira zotupa, kapena kukonzekera njira zochitira opaleshoni.
Mtengo ndi kupezeka mosavuta: Makina a X-ray nthawi zambiri amakhala otsika mtengo ndipo amapezeka kwambiri m'malo osiyanasiyana azaumoyo, kuphatikizapo madipatimenti ogonera odwala ndi azadzidzidzi. Ma CT scanner, ngakhale amapereka luso lapamwamba lojambula zithunzi, ndi okwera mtengo kwambiri ndipo mwina sangapezeke mosavuta m'malo onse azaumoyo.
Pomaliza
Mwachidule, zonse ziwiriMachubu a X-rayndipo ma CT scanner amagwira ntchito yofunika kwambiri pa kujambula zithunzi zachipatala, ndipo chilichonse chili ndi ubwino wake komanso zofooka zake. Kumvetsetsa kusiyana pakati pa matekinoloje awiriwa kungathandize opereka chithandizo chamankhwala kupanga zisankho zolondola za njira yojambulira zithunzi yomwe ili yabwino kwa odwala awo. Pamene ukadaulo ukupitirira kupita patsogolo, kuphatikiza kwa X-ray ndi CT imaging mwina kukupitilizabe kusintha, zomwe zikuwonjezera luso lozindikira matenda komanso chisamaliro cha odwala.
