Ultrasound thev naus laus zis tau hloov pauv txoj hauv kev kho mob cov kws kho mob kuaj thiab kho lawv cov neeg mob. Ib qho ntawm cov kev faib tawm tseem ceeb ntawm ultrasound yog qhov sib txawv ntawm cov xim dub thiab dawb (B&W) thiab xim ultrasound duab. Kab lus no yuav qhia txog qhov sib txawv ntawm ob qho tib si thiab muab kev nkag siab txog kev xaiv cov txheej txheem zoo tshaj plaws rau qhov xwm txheej.
Dub thiab dawb ultrasound hais txog cov txheej txheem ib txwm siv ntawm ultrasound imaging uas daim duab tso tawm yog xim dub thiab dawb, nrog ntau qhov ntxoov grey. Cov txheej txheem kev yees duab no muaj txiaj ntsig zoo hauv kev pom cov qauv ntawm lub cev, cov ntaub so ntswg, thiab cov hlab ntsha, vim nws muab qhov zoo sib xws. Nrog B&W ultrasound, ib zaus ntawm lub suab yoj tawm thiab nqus los ntawm cov ntaub so ntswg, tsim cov duab monochrome ntawm qhov screen. Cov txheej txheem no yog qhov nyiam los ntawm cov kws kho mob uas xav tau cov ntaub so ntswg sib sib zog nqus xws li txheeb xyuas cov qog lossis kuaj cov fetuses thaum cev xeeb tub.
Xim ultrasound, ntawm qhov tod tes, siv ntau zaus ntawm lub suab nthwv dej los tsim cov duab hauv xim. Cov txheej txheem no tshwj xeeb tshaj yog muaj txiaj ntsig zoo hauv kev txheeb xyuas thiab sib txawv ntawm cov ntaub so ntswg sib txawv, piv txwv li, txheeb xyuas cov ntshav ntws hauv cov hlab plawv. Xim ultrasound tuaj yeem sib txawv ntawm cov ntshav khiav mus rau lossis deb ntawm lub transducer, pab txheeb xyuas qhov muaj peev xwm txhaws thiab qhov txawv txav. Nws yog tshwj xeeb tshaj yog pab tau nyob rau hauv kev kuaj mob ntawm cov mob xws li peripheral vascular thiab arterial kab mob.
Thaum xaiv cov xim dub thiab dawb thiab xim xim ultrasound, lub hom phiaj ntawm cov duab ua lub luag haujlwm tseem ceeb. Yog tias lub hom phiaj yog txhawm rau pom cov qauv ntawm lub cev, cov ntaub so ntswg, lossis cov hlab ntsha, ultrasound dub thiab dawb yog cov txheej txheem nyiam vim nws cov duab zoo sib xws. Yog tias lub hom phiaj yog los txiav txim siab thiab sib txawv ntau hom ntaub so ntswg lossis ntshav ntws, xim ultrasound yog cov txheej txheem ntawm kev xaiv.
Nyob rau hauv xaus, dub thiab dawb ultrasound thiab xim ultrasound yog ob qho tib si invaluable cov tswv yim siv nyob rau hauv kev kuaj mob. Qhov sib txawv tseem ceeb ntawm ob yog qhov muaj peev xwm pom cov qauv lossis sib txawv ntawm cov ntaub so ntswg thiab cov ntshav ntws. Paub tias yuav siv cov txheej txheem twg yog nyob ntawm qhov kev kuaj xyuas thiab cov ntaub ntawv uas yuav tsum tau ua. Ob txoj kev ua tau zoo hauv lawv lub hom phiaj thiab muab cov kws kho mob cov txiaj ntsig ntawm kev pom, kev txheeb xyuas, thiab kev kuaj mob.
