Puas yog Dub-thiab-dawb txhais tau tias tsis muaj Doppler?
Ultrasound thev naus laus zis yog lub hauv paus ntawm kev kuaj mob niaj hnub no, muab qhov tsis muaj kev cuam tshuam thiab siv tau zoo kom pom cov qauv sab hauv ntawm lub cev. Ntawm ntau hom ultrasound, dub-thiab-dawb (lossis greyscale) ultrasound thiab Doppler ultrasound yog ob pawg thawj coj uas feem ntau ua rau tsis meej pem. Ib lo lus nug ntau yog seb puas yog dub-thiab-dawb ultrasound inherently txhais tau tias tsis muaj Doppler peev xwm. Cov kab lus no yog tsom los piav qhia qhov teeb meem no thiab muab kev nkag siab zoo ntawm ob qho tib si technologies, lawv qhov sib txawv, thiab lawv cov kev siv.
Dab tsi yog Dub-thiab-dawb Ultrasound?
Dub-thiab-dawb ultrasound, tseem hu ua greyscale ultrasound, yog cov feem ntau ib txwm siv thiab dav siv daim ntawv ntawm ultrasound imaging. Nws tsim cov duab sib txawv ntawm cov xim grey, sawv cev sib txawv ntawm cov ntaub so ntswg thiab lub cev.
Yuav ua li cas Dub-thiab-dawb Ultrasound ua haujlwm
Cov txheej txheem muaj xws li ib tug transducer, uas emits high-frequency suab nthwv dej rau hauv lub cev. Cov suab nthwv dej no tawm ntawm cov qauv sab hauv thiab rov qab mus rau lub transducer li echoes. Cov echoes tau hloov mus rau hauv cov duab pom los ntawm lub tshuab ultrasound. Cov xim sib txawv ntawm grey hauv cov duab sawv cev rau ntau theem ntawm cov ntaub so ntswg ntom ntom: cov qauv ntom ntom zoo li cov pob txha tshwm dawb, thaum cov qauv tsis tshua muaj ntom ntom zoo li cov dej uas muaj dej ntau dua.
Daim ntawv thov ntawm Dub-thiab-dawb Ultrasound
Dub-thiab-dawb ultrasound yog muaj ntau yam thiab siv nyob rau hauv ntau yam kev kho mob:
