Cov Assange Granite rau kev sib sau Tomography?

Lub rooj sib sau ua ke rau Tom Cobraphy (CT) yog tus qauv tshwj xeeb uas tau siv nyob rau hauv kev kho mob teb kom ua tau zoo thiab meej scans ntawm tib neeg lub cev. CT scanning yog ib qho kev ntsuas thev naus laus zis tshaj plaws hauv kev ua haujlwm ua haujlwm, vim nws ua rau cov kws kho mob kom kuaj xyuas ntau yam. Cov cuab yeej ntsuas rau CT scans siv cov xas ray thev naus laus zis los tsim cov duab 3D ntawm lub cev, uas tso cai rau cov kws kho mob mus nrhiav thiab txheeb xyuas qhov kev ua kom raug mob, thiab cov kab mob uas muaj kev pom zoo me me.

Cov sib dhos Granite rau ct muaj feem ntau ntawm ob ntu: granite grantry thiab graniteuteop. Lub Gantry yog lub luag haujlwm rau tsev nyob cov cuab yeej xav tau thiab tig ib ncig tus neeg mob lub sijhawm ntsuas. Hauv kev sib piv, lub Tabletop txhawb tus neeg mob lub qhov hnyav thiab ua kom muaj kev ruaj khov thiab immobility thaum lub scan. Cov khoom siv no tau tsim los ntawm cov khoom zoo, ruaj khov, uas muaj cov khoom zoo tshaj plaws kom tsis txhob muaj kev sib txawv ntawm ib puag ncig, xws li cov av noo hloov.

Cov granite gantry yog tsim los sib xyaw sib txawv ntawm cov khoom sib txawv uas yuav tsum tau rau CT scanning, xws li lub raj xoo hluav taws xob, ntsuas hluav taws xob, thiab cov txheej txheem collimation. Lub raj xoo hluav taws xob yog nyob sab hauv lub gantry, qhov chaw nws emits x-rays uas nkag rau lub cev kom tsim 3D duab. Cov ntes array, uas tseem nyob sab hauv lub gantry, ntes cov x-ray uas dhau los ntawm lub cev thiab tom ntej rau lub khoos phis tawj rau kev rov tsim kho cov duab. Txheej txheem sib zog yog ib qho kev siv tshuab siv los nqaim lub xoo ci txhawm rau txo cov hluav taws xob uas cov neeg mob kis tau rau thaum lub scan.

Lub graniteuthop yog ib qho tseem ceeb heev ntawm CT system zoo li. Nws muab ib lub platform uas txhawb cov neeg mob lub cev thaum luam tawm thiab ua kom pom tseeb tias txoj haujlwm ruaj khov, tsis muaj peev xwm tswj hwm thaum tag nrho cov txheej txheem. Lub Tabletop tseem tau nruab nrog cov kev qhia tshwj xeeb, xws li cov hlua khi, cov cuab yeej, uas paub meej tias lub cev yog nyob rau hauv txoj haujlwm yog qhov kev ntsuas. Cov ntsiav tshuaj yuav tsum yog txoj kev du, thiab dawb los ntawm kev deformation lossis distortion los tiv thaiv cov khoom cuav hauv cov duab tsim tawm.

Hauv kev xaus, cov sib dhos granite rau CT scanning plays lub luag haujlwm tseem ceeb hauv qhov tseeb thiab precision ntawm cov txheej txheem kho mob. Kev siv cov khoom siv zoo granite hauv cov cuab yeej kho mob kom muaj cov khoom siv kho mob, thiab cov khoom siv hluav taws xob uas tseem ceeb rau kev ua tiav cov kev xav tau zoo tshaj plaws. Nrog kev nkag siab zoo dua ntawm cov qauv tsim thiab kev sib xyaw ntawm cov kev nce qib tshiab hauv cov khoom sib xyaw thiab tsis tshua muaj kev phem rau cov neeg mob.
