Ib lub rooj sib dhos granite rau Computed Tomography (CT) yog ib qho kev tsim tshwj xeeb uas siv rau hauv kev kho mob los ua qhov kev ntsuas qhov tseeb thiab meej ntawm tib neeg lub cev. CT scanning yog ib qho ntawm cov kev nce qib tseem ceeb tshaj plaws hauv kev kho mob, vim nws ua rau cov kws kho mob kuaj mob ntau yam mob kom raug. Cov khoom siv thaij duab rau CT scans siv cov thev naus laus zis X-ray los tsim cov duab 3D ntawm lub cev, uas tso cai rau cov kws kho mob nrhiav thiab txheeb xyuas cov kev loj hlob tsis zoo, kev raug mob, thiab cov kab mob nrog kev cuam tshuam tsawg kawg nkaus.
Lub rooj sib dhos granite rau CT muaj ob ntu: lub gantry granite thiab lub rooj granite. Lub gantry yog lub luag haujlwm rau kev tso cov khoom siv thaij duab thiab tig ib puag ncig tus neeg mob thaum lub sijhawm luam theej duab. Qhov sib txawv, lub rooj txhawb nqa tus neeg mob qhov hnyav thiab ua kom muaj kev ruaj khov thiab tsis txav tau thaum lub sijhawm luam theej duab. Cov khoom no yog ua los ntawm cov granite zoo, ruaj khov, uas muaj cov khoom zoo tshaj plaws los tiv thaiv kev cuam tshuam los ntawm kev hloov pauv ntawm ib puag ncig, xws li kev hloov pauv kub thiab av noo.
Lub granite gantry no yog tsim los ua kom muaj ntau yam khoom sib txawv uas xav tau rau CT scanning, xws li lub raj X-ray, lub detector array, thiab collimation system. Lub raj X-ray nyob sab hauv lub gantry, qhov chaw uas nws tso tawm cov X-rays uas nkag mus rau hauv lub cev kom tsim tau ib daim duab 3D. Lub detector array, uas kuj nyob sab hauv lub gantry, ntes cov X-rays uas hla lub cev thiab xa mus rau lub computer system rau kev tsim cov duab dua tshiab. Lub collimation system yog ib lub tshuab siv los ua kom lub X-ray beam nqaim dua kom txo tau cov hluav taws xob uas cov neeg mob raug thaum lub sijhawm scan.
Lub rooj granite yog ib qho tseem ceeb ntawm lub tshuab CT thiab. Nws muab ib lub platform uas txhawb nqa tus neeg mob qhov hnyav thaum lub sijhawm luam theej duab thiab ua kom muaj qhov chaw ruaj khov, tsis txav mus los thaum lub sijhawm tag nrho. Lub rooj kuj tseem muaj cov khoom siv tshwj xeeb rau kev tso chaw, xws li cov hlua khi, cov ncoo, thiab cov khoom siv immobilization, uas ua kom lub cev nyob rau hauv qhov chaw zoo rau kev luam theej duab. Lub rooj yuav tsum du, tiaj tus, thiab tsis muaj kev hloov pauv lossis kev cuam tshuam kom tiv thaiv cov khoom cuav hauv cov duab tsim tawm.
Xaus lus, lub rooj sib dhos granite rau CT scanning 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 ua rau muaj kev ruaj khov ntawm cov khoom siv, kev ruaj khov thermal, thiab cov khoom siv nthuav dav qis-thermal, uas yog qhov tseem ceeb rau kev ua tiav cov txiaj ntsig zoo tshaj plaws. Nrog kev nkag siab zoo dua ntawm cov yam ntxwv tsim thiab kev koom ua ke ntawm cov kev nce qib tshiab hauv cov khoom, yav tom ntej ntawm CT scanning zoo li ci dua thiab tsis cuam tshuam rau cov neeg mob.
