Ultrasound


B-ultrasound yog cov khoom siv soj ntsuam uas siv ultrasound los nkag siab txog cov qauv ntawm lub cev.


B-ultrasound saws cov dub-thiab-dawb ultrasound kuaj thev naus laus zis thaum ntxov. Los ntawm emitting ultrasound, ultrasound yuav tsim echoes thaum nws ntsib qhov txwv tsis pub hnav. Lub khoos phib tawj khaws cov echoes no thiab hloov mus ua cov duab sib piv rau coj los tso tawm ntawm lub vijtsam.


Cov duab ntsuas los ntawm kev sojntsuam ultrasound yog xim dub thiab dawb, thiab tsuas yog cov ntaub so ntswg cov qauv ntawm tus menyuam hauv plab tuaj yeem pom, ntsuas qhov loj ntawm lub taub hau thiab qhov ntev ntawm lub cev.



Xim Doppler


Xim Doppler ultrasoundtsis yog qhov tseeb" xim B-ultrasound", tab sis raws kev coj ua B-ultrasound, cov xim-Doppler ultrasound kuaj thiab tshuaj thev naus laus zis yuav raug siv los sau npe rau lub plawv, ntshav txaus thiab lwm yam ntsuas, uas tau pom los ntawm cov xim ultrasound. Cov duab yog feem ntau liab thiab xiav.


Cov thev naus laus zis no tuaj yeem soj ntsuam cov ntshav khiav ntawm tus menyuam hauv plab, uas yog qhov zoo rau kev tu ncua sijhawm ntawm kev muaj menyuam hauv plab. Piv txwv, yog muaj ntshav ntws nyob rau ntawm caj dab ntawm tus me nyuam, nws txhais tau tias txoj hlab ntaws muaj qhov txhab nyob ib ncig ntawm caj dab, uas tuaj yeem ua rau tsis haum.



Los ntawm cov lus piav qhia saum toj no, peb tuaj yeem txiav txim siab tias cov qauv ntawm B-ultrasound thiab xim Doppler ultrasound kev kuaj xyuas zoo sib xws. Lawv yog ob qho tib si kev kuaj ultrasound, thiab xim Doppler ultrasound yog qib ntau dua li B-ultrasound technology. Nws tuaj yeem pom cov khoom faib tawm ntawm cov ntshav txaus thiab qhia txog qhov xwm txheej faib tawm ntawm cov ntshav txaus. Nws yog qhov txiaj ntsig zoo rau kev txheeb xyuas qhov mob vascular, nrog rau cov yam ntxwv ntawm cov ntshav ntws, xws li nrawm thiab kev taw qhia.
