Hauv kev siv tshuab thaij duab kho mob, thev naus laus zis ua lub luag haujlwm tseem ceeb hauv kev muab cov duab tseeb thiab ntxaws ntxaws rau kev kuaj mob thiab kev kho mob. Ib qho tseem ceeb ntawm cov thev naus laus zis no yog lub raj xa duab anode X-ray uas tig tau. Lub cuab yeej siab heev no muaj ntau yam zoo uas tseem ceeb heev hauv kev siv tshuab thaij duab kho mob.
Ua ntej tshaj plaws,Cov raj xa hluav taws xob anode tig muab kev ua tau zoo dua li cov raj anode ruaj khov. Kev tig lub anode ua rau thaj chaw loj dua, ua rau muaj zog dua thiab cua sov ntau dua. Qhov no txhais tau tias cov raj no tuaj yeem tsim cov duab zoo dua thiab cov duab daws teeb meem siab dua, ua rau lawv yog thawj qhov kev xaiv rau cov kws kho mob.
Ntxiv rau qhov ua tau zoo tshaj plaws, cov raj xa duab anode X-ray uas tig tau muaj kev ywj pheej thiab kev siv tau ntau yam. Nrog rau lub peev xwm hloov qhov ceev thiab lub kaum sab xis ntawm kev tig, cov raj no tuaj yeem hloov kho kom tau raws li qhov xav tau ntawm cov txheej txheem kho mob sib txawv. Qhov kev ywj pheej no ua kom cov kws kho mob muaj kev nkag mus rau cov duab zoo tshaj plaws rau kev kuaj mob thiab kev npaj kho mob kom raug.
Tsis tas li ntawd xwb, cov raj xa duab X-ray anode uas tig tau yog tsim los kom ntev lub raj lub neej thiab ua kom nws ua haujlwm tau zoo dua. Lub anode uas tig tau faib cov cua sov uas tsim thaum lub sijhawm thaij duab kom sib npaug dua, txo qhov kev pheej hmoo ntawm kev kub dhau thiab ua kom lub raj lub neej ntev dua. Qhov no txo cov nqi kho thiab lub sijhawm tsis ua haujlwm, ua rau nws yog qhov kev xaiv uas pheej yig thiab txhim khu kev qha rau cov chaw kho mob.
Lwm qhov laj thawj uas ua rau cov raj xa duab anode X-ray tig tau nrov heev hauv kev lag luam duab kho mob yog lawv lub peev xwm los tsim ntau yam zog X-ray. Los ntawm kev kho qhov ceev thiab lub kaum sab xis, cov raj no tuaj yeem tsim cov duab X-ray ntawm ntau qib zog, ua rau muaj cov txheej txheem duab zoo dua thiab raug dua. Qhov no muaj txiaj ntsig tshwj xeeb thaum thaij duab ntau qhov ntawm lub cev uas xav tau ntau qib kev nkag mus thiab kev daws teeb meem.
Tsis tas li ntawd,Cov raj xa hluav taws xob anode tigkuj zoo tagnrho rau cov ntawv thov kev kho mob xws li CT scans thiab angiography. Lawv qhov kev ua tau zoo thiab kev ua kom txias zoo dua ua rau lawv zoo tagnrho rau cov txheej txheem nyuaj no, qhov twg cov duab zoo thiab qhov tseeb yog qhov tseem ceeb.
Hauv kev xaus,Cov raj xa hluav taws xob anode tig yog ib qho thev naus laus zis muaj nqis thiab tsis tuaj yeem tsis tau hauv kev thaij duab kho mob. Cov raj no muaj kev ua tau zoo tshaj plaws, kev ywj pheej, kev ua haujlwm zoo thiab lub peev xwm los tsim ntau yam zog X-ray, ua rau lawv yog thawj qhov kev xaiv rau cov kws kho mob uas muab qhov tseeb thiab kev ntseeg siab ntawm lawv cov khoom siv thaij duab. Thaum thev naus laus zis txuas ntxiv mus, qhov tseem ceeb ntawm kev tig cov raj X-ray anode hauv kev thaij duab kho mob yuav tsuas yog txuas ntxiv loj hlob, ua rau lawv yog ib feem tseem ceeb ntawm kev kho mob.
