Kodi gulu la granite la Computed Tomography ndi chiyani?

Chojambulira cha granite cha Computed Tomography (CT) ndi kapangidwe kapadera komwe kamagwiritsidwa ntchito m'zachipatala kuti achite ma scan olondola komanso olondola kwambiri a thupi la munthu. Kujambula kwa CT ndi chimodzi mwa zinthu zofunika kwambiri paukadaulo pankhani yojambula zithunzi zachipatala, chifukwa zimathandiza madokotala kuzindikira matenda osiyanasiyana molondola. Zipangizo zojambulira zithunzi za CT scan zimagwiritsa ntchito ukadaulo wa X-ray kuti apange chithunzi cha 3D cha thupi, zomwe zimathandiza madokotala kupeza ndi kuzindikira kukula kosazolowereka, kuvulala, ndi matenda omwe alibe kufalikira kwakukulu.

Chopangira granite cha CT chimakhala ndi magawo awiri: granite gantry ndi granite tabletop. Gantryyo imayang'anira kusunga zida zojambulira zithunzi ndikuzungulira wodwalayo panthawi yojambulira. Mosiyana ndi zimenezi, tabletop imathandizira kulemera kwa wodwalayo ndikuonetsetsa kuti kukhazikika ndi kusasuntha panthawi yojambulira. Zigawozi zimapangidwa ndi granite yapamwamba komanso yolimba, yomwe ili ndi makhalidwe abwino kwambiri kuti ipewe kusokonekera komwe kumachitika chifukwa cha kusintha kwa chilengedwe, monga kusintha kwa kutentha ndi chinyezi.

Gantry ya granite yapangidwa kuti iphatikizepo zinthu zosiyanasiyana zofunika pa CT scanning, monga chubu cha X-ray, detector array, ndi collimation system. Chubu cha X-ray chili mkati mwa gantry, komwe chimatulutsa ma X-ray omwe amalowa m'thupi kuti apange chithunzi cha 3D. Gulu la detector, lomwe lilinso mkati mwa gantry, limatenga ma X-ray omwe amadutsa m'thupi ndikuwatumiza ku kompyuta kuti akakonzenso chithunzi. Dongosolo la collimation ndi njira yomwe imagwiritsidwa ntchito kuchepetsa kuwala kwa X-ray kuti achepetse kuchuluka kwa kuwala komwe odwala amakumana nako panthawi ya scan.

Pamwamba pa tebulo la granite ndi gawo lofunikira kwambiri pa dongosolo la CT. Limapereka nsanja yothandizira kulemera kwa odwala panthawi yojambula ndikuwonetsetsa kuti malo okhazikika komanso osasuntha amasungidwa nthawi yonseyi. Pamwamba pa tebulo palinso zida zina zothandizira, monga zingwe, ma cushion, ndi zida zoletsa kuyenda, zomwe zimaonetsetsa kuti thupi lili pamalo oyenera ojambulira. Pamwamba pa tebulo payenera kukhala losalala, lathyathyathya, komanso lopanda kusintha kulikonse kuti zithunzi zisawonongeke.

Pomaliza, kusonkhana kwa granite kuti mujambule CT scanning kumachita gawo lofunika kwambiri pa kulondola ndi kulondola kwa njira yojambulira zithunzi zachipatala. Kugwiritsa ntchito granite yapamwamba kwambiri mu zida zachipatala kumawonjezera kukhazikika kwa makina, kukhazikika kwa kutentha, komanso kukula kwa zida zomwe sizitentha kwambiri, zomwe ndizofunikira kwambiri kuti mupeze zotsatira zabwino kwambiri zojambulira. Ndi kumvetsetsa bwino mawonekedwe a kapangidwe kake komanso kuphatikiza kupita patsogolo kwatsopano m'zigawo, tsogolo la CT scanning likuwoneka lowala komanso losasokoneza odwala.
