B/W Ultrasound thiab Xim Doppler
Ultrasound tshuab yog ib qho cuab yeej siv hauv cov tshuaj niaj hnub, dav siv rau kev kuaj mob. Txawm li cas los xij, muaj ntau hom kev siv tshuab ultrasound, suav nrog dub-thiab-dawb ultrasound thiab xim Doppler ultrasound, txhua tus nrog nws cov ntawv tshwj xeeb thiab qhov zoo. Kab lus no yog npaj los muab kev nkag siab zoo ntawm ob hom ultrasound, lawv qhov sib txawv, thiab lawv cov kev siv tshwj xeeb hauv kev kho mob.
Dab tsi yog Dub-thiab-dawb Ultrasound?
Dub-thiab-dawb ultrasound, tseem hu ua greyscale ultrasound, yog feem ntau thiab ib txwm daim ntawv ntawm ultrasound imaging. Nws siv cov suab nrov nrov los tsim cov duab ntawm cov qauv hauv lub cev. Cov duab no tau tshwm sim nyob rau hauv ntxoov grey, li no lub npe greyscale.
Yuav ua li cas Dub-thiab-dawb Ultrasound ua haujlwm
Cov txheej txheem muaj xws li ib tug transducer, ib tug handheld ntaus ntawv uas emissions suab nthwv dej thiab ntes cov echoes uas rov qab los ntawm lub cev. Cov echoes tau hloov mus rau hauv cov duab pom ntawm ib qho screen. Qhov sib txawv ntawm cov ntaub so ntswg thiab cov khoom nruab nrog cev muaj kev cuam tshuam cov suab tsis sib txawv, tsim cov xim sib txawv ntawm grey uas tsim cov duab.
Daim ntawv thov ntawm Dub-thiab-dawb Ultrasound
Dub-thiab-dawb ultrasound yog siv dav thoob plaws ntau yam kev kho mob vim nws ntau yam thiab muaj txiaj ntsig hauv kev pom cov nqaij mos. Qee cov ntawv thov siv xws li:
Obstetrics thiab Gynecology: Txhawm rau saib xyuas tus menyuam hauv plab, ntsuas kev noj qab haus huv ntawm lub tsev menyuam thiab zes qe menyuam, thiab qhia qee cov txheej txheem.

Color Doppler Ultrasound yog dab tsi?
Color Doppler ultrasound yog ib qho kev ua tiav ntawm ultrasound uas ntxiv cov xim rau cov duab grayscale, tso cai rau pom cov ntshav ntws hauv cov hlab ntsha thiab lub cev. Nws siv cov nyhuv Doppler, uas ntsuas kev hloov pauv hauv zaus ntawm lub suab nthwv dej thaum lawv dhia tawm ntawm cov khoom txav, xws li cov qe ntshav liab.
Xim Doppler Ultrasound ua haujlwm li cas
Ntxiv nrog rau cov duab greyscale, xim Doppler ultrasound ua cov suab nthwv dej rov qab los txhawm rau txheeb xyuas cov ntshav txav. Nws mam li muab cov xim sib txawv los sawv cev rau cov kev taw qhia thiab ceev ntawm cov ntshav khiav. Feem ntau, cov xim liab thiab xiav yog siv: liab qhia cov ntshav ntws mus rau lub transducer, thaum xiav qhia cov ntshav ntws tawm ntawm nws.
Daim ntawv thov ntawm Xim Doppler Ultrasound
Xim Doppler ultrasound muab cov ntaub ntawv tseem ceeb txog cov ntshav khiav, ua rau nws tseem ceeb hauv ntau yam kev kuaj mob thiab kev kho mob. Nws cov ntawv thov suav nrog:
