Granite yog cov khoom siv nrov rau lub hauv paus ntawm cov khoom lag luam suav tomography (CT) vim nws qhov zoo heev.Hauv tsab xov xwm no, peb yuav tshawb xyuas cov txiaj ntsig no thiab vim li cas granite yog qhov kev xaiv zoo tshaj plaws rau CT tshuab.
Ua ntej, granite muaj exceptional mechanical stability.Nws yog cov khoom siv ruaj khov thiab ntom ntom, ua rau nws zoo tagnrho rau lub hauv paus rau cov tshuab CT.Granite tsis warp, twist, los yog deform nyob rau hauv lub siab, uas yog ib qho tseem ceeb nyob rau hauv kom ntseeg tau qhov tseeb ntawm CT scans.Qhov kev ruaj ntseg no tseem yog qhov tseem ceeb los xyuas kom meej tias lub tshuab tsis vibrating thiab cuam tshuam qhov zoo ntawm cov duab.
Qhov thib ob, granite muaj cov coefficient tsawg ntawm thermal expansion.Qhov no txhais tau hais tias nws tsis nthuav lossis cog lus loj heev thaum raug kev hloov pauv ntawm qhov kub thiab txias, uas yog qhov tseem ceeb rau cov tshuab CT uas yuav tsum tau tswj xyuas lawv qhov tseeb hauv qhov chaw ua haujlwm sib txawv.Qhov qis coefficient ntawm thermal expansion kuj txo qhov kev pheej hmoo ntawm deformation lossis misalignment ntawm gantry, uas tuaj yeem cuam tshuam qhov zoo ntawm CT scans.
Thirdly, granite muaj zoo heev vibration damping yam ntxwv.Kev vibration yog ib qho kev sib tw tseem ceeb hauv cov tshuab CT, vim nws tuaj yeem cuam tshuam qhov zoo ntawm cov duab.Granite lub vibration damping yam ntxwv tso cai rau cov khoom nqus oscillations yam tsis tau xa lawv mus rau lub tshuab CT, uas yuav pab ua kom zoo scans.
Plaub, granite muaj qib siab ntawm tshuaj lom neeg ruaj khov.Nws yog non-reactive rau feem ntau cov tshuaj thiab tuaj yeem tiv taus cov tshuaj hnyav los yog acids.Qhov no ua rau lub hauv paus granite zoo tagnrho rau CT tshuab siv hauv kev tsim khoom lossis kev tshawb fawb cov chaw uas muaj kev pheej hmoo ntawm kev raug tshuaj lom neeg siab.
Thaum kawg, granite yog yooj yim los tswj.Nws tsis xeb, corrode, los yog degrade nyob rau lub sij hawm, ua rau nws yog ib tug zoo meej cov khoom siv rau lub sij hawm ntev.Cov khoom siv kuj muaj qhov zoo khawb tsis kam, ua kom muaj zog thiab ua haujlwm ntev, uas txo cov nqi txij nkawm.
Hauv kev xaus, granite yog cov khoom siv zoo tshaj plaws rau lub hauv paus ntawm kev lag luam CT cov cav tov vim nws cov khoom siv zoo heev, tsis tshua muaj coefficient ntawm thermal expansion, vibration damping yam ntxwv, siab tshuaj stability thiab yooj yim txij nkawm.Nws yog cov khoom siv txhim khu kev qha rau kev lag luam uas xav tau kev soj ntsuam zoo rau kev tswj xyuas kom zoo, kev tshawb fawb, thiab kev txhim kho daim ntawv thov.Xaiv lub hauv paus granite rau koj lub tshuab CT yog qhov kev nqis peev zoo hauv kev ua kom qhov tseeb thiab kev ntseeg siab ntawm koj cov kev soj ntsuam rau ntau xyoo tom ntej.
