Granite yog ib yam khoom siv nrov rau lub hauv paus ntawm cov khoom siv computer tomography (CT) vim nws muaj ntau yam zoo. Hauv tsab xov xwm no, peb yuav tshawb nrhiav cov txiaj ntsig no thiab vim li cas granite thiaj yog qhov kev xaiv zoo tshaj plaws rau CT tshuab.
Ua ntej, granite muaj kev ruaj khov zoo heev. Nws yog ib yam khoom khov kho thiab ntom ntom, ua rau nws zoo tagnrho rau lub hauv paus rau cov tshuab CT hauv kev lag luam. Granite tsis warp, twist, lossis deform nyob rau hauv siab, uas yog qhov tseem ceeb hauv kev ua kom raug ntawm CT scans. Qhov kev ruaj khov no kuj tseem ceeb kom ntseeg tau tias lub tshuab tsis co thiab ua rau cov duab tsis zoo.
Qhov thib ob, granite muaj cov coefficient qis ntawm thermal expansion. Qhov no txhais tau tias nws tsis nthuav dav lossis cog lus ntau thaum raug rau qhov kub thiab txias hloov pauv, uas yog qhov tseem ceeb rau cov tshuab CT kev lag luam uas xav tau tswj lawv qhov tseeb hauv ntau qhov chaw ua haujlwm sib txawv. Cov coefficient qis ntawm thermal expansion kuj txo qhov kev pheej hmoo ntawm kev hloov pauv lossis kev tsis sib haum ntawm lub gantry, uas tuaj yeem cuam tshuam rau qhov zoo ntawm CT scans.
Qhov thib peb, granite muaj cov yam ntxwv zoo heev rau kev co. Kev co yog qhov nyuaj heev hauv cov tshuab CT kev lag luam, vim nws tuaj yeem cuam tshuam rau qhov zoo ntawm cov duab. Granite cov yam ntxwv ntawm kev co tso cai rau cov khoom siv los nqus cov oscillations yam tsis tau xa mus rau lub tshuab CT, uas pab tsim cov duab zoo.
Qhov thib plaub, granite muaj kev ruaj khov tshuaj lom neeg siab. Nws tsis tshua muaj zog rau feem ntau cov tshuaj lom neeg thiab tuaj yeem tiv taus cov tshuaj lom neeg lossis cov kua qaub hnyav. Qhov no ua rau lub hauv paus granite zoo tagnrho rau cov tshuab CT siv hauv kev tsim khoom lossis kev tshawb fawb qhov twg muaj kev pheej hmoo ntawm kev raug tshuaj lom neeg siab.
Thaum kawg, granite yooj yim rau kev saib xyuas. Nws tsis xeb, tsis lwj, lossis lwj mus raws sijhawm, ua rau nws yog cov khoom siv zoo meej rau kev siv mus sij hawm ntev. Cov khoom siv kuj muaj cov yam ntxwv zoo tiv taus khawb, ua kom ruaj khov thiab siv tau ntev, uas txo cov nqi kho.
Xaus lus, granite yog cov khoom siv zoo tshaj plaws rau lub hauv paus ntawm cov tshuab CT kev lag luam vim nws qhov kev ruaj khov zoo heev, cov coefficient qis ntawm thermal nthuav dav, cov yam ntxwv vibration damping, kev ruaj khov tshuaj lom neeg siab thiab yooj yim ntawm kev saib xyuas. Nws yog cov khoom siv txhim khu kev qha rau cov lag luam uas xav tau cov kev luam theej zoo rau kev tswj hwm zoo, kev tshawb fawb, thiab kev txhim kho. Kev xaiv lub hauv paus granite rau koj lub tshuab CT kev lag luam yog kev nqis peev zoo hauv kev ua kom ntseeg tau qhov tseeb thiab kev ntseeg siab ntawm koj cov kev luam theej rau ntau xyoo tom ntej.
