Lub granite sib dhos rau Computed Tomography (CT) yog ib qho kev tsim tshwj xeeb uas tau siv hauv kev kho mob kom ua tau zoo thiab raug kuaj ntawm tib neeg lub cev.CT scanning yog ib qho tseem ceeb tshaj plaws kev nce qib hauv kev kho mob, vim nws ua rau cov kws kho mob tuaj yeem kuaj xyuas ntau yam kev mob nkeeg kom raug.Cov cuab yeej siv duab rau CT scans siv X-ray technology los tsim 3D duab ntawm lub cev, uas tso cai rau cov kws kho mob nrhiav thiab txheeb xyuas qhov kev loj hlob txawv txav, raug mob, thiab cov kab mob uas muaj kev cuam tshuam tsawg heev.
Lub granite sib dhos rau CT muaj feem ntau ntawm ob qhov chaw: granite gantry thiab granite tabletop.Lub gantry yog lub luag haujlwm rau vaj tsev cov khoom siv duab thiab tig ib ncig ntawm tus neeg mob thaum lub sijhawm scanning.Piv txwv li, lub ntsiav tshuaj txhawb tus neeg mob qhov hnyav thiab ua kom muaj kev ruaj ntseg thiab tsis muaj zog thaum lub sijhawm scan.Cov khoom no yog tsim los ntawm cov khoom zoo, ruaj khov granite, uas muaj cov khoom zoo tshaj plaws kom tsis txhob muaj kev cuam tshuam los ntawm ib puag ncig kev hloov pauv, xws li kub thiab av noo hloov.
Granite gantry yog tsim los ua ke cov khoom sib txawv uas xav tau rau CT scanning, xws li X-ray raj, ntes array, thiab kev sib tsoo.X-ray raj yog nyob rau hauv lub gantry, qhov twg nws emits X-rays nkag mus rau hauv lub cev los tsim ib tug 3D duab.Lub detector array, uas tseem nyob rau hauv lub gantry, ntes cov X-rays uas hla lub cev thiab xa mus rau lub computer system rau cov duab reconstruction.Lub kaw lus collimation yog ib qho cuab yeej siv los nqaim lub X-ray beam kom txo tau cov hluav taws xob uas cov neeg mob raug thaum lub sij hawm scan.
Granite tabletop yog ib qho tseem ceeb ntawm CT system thiab.Nws muab lub platform uas txhawb nqa cov neeg mob qhov hnyav thaum kuaj xyuas thiab xyuas kom meej tias qhov chaw ruaj khov, tsis muaj zog yog tswj xyuas thaum tag nrho cov txheej txheem.Lub ntsiav tshuaj kuj tau nruab nrog cov kev pab tshwj xeeb, xws li cov hlua, cushions, thiab immobilization cov cuab yeej, uas xyuas kom meej tias lub cev nyob rau hauv txoj hauj lwm zoo rau scanning.Lub tabletop yuav tsum du, tiaj tus, thiab tsis muaj deformation los yog distortion los tiv thaiv tej khoom cuav nyob rau hauv cov duab generated.
Hauv kev xaus, lub granite sib dhos rau CT scan ua lub luag haujlwm tseem ceeb hauv qhov tseeb thiab qhov tseeb ntawm cov txheej txheem kho mob.Kev siv cov granite zoo hauv cov khoom siv kho mob txhim kho kev ruaj ntseg, thermal stability, thiab qis-thermal expansion zog ntawm cov cuab yeej, uas yog qhov tseem ceeb rau kev ua tiav cov txiaj ntsig zoo tshaj plaws.Nrog rau kev nkag siab zoo dua ntawm cov qauv tsim thiab kev sib koom ua ke ntawm kev nce qib tshiab hauv cov khoom, lub neej yav tom ntej ntawm CT scan zoo li ci ntsa iab thiab tsis zoo rau cov neeg mob.
