Xim Doppler ultrasound feem ntau siv tshuab autocorrelation rau Doppler teeb liab ua.Cov ntshav ntws teeb liab tau txais los ntawm autocorrelation thev naus laus zis yog xim-coded thiab superimposed ntawm ob sab duab hauv lub sijhawm tiag tiag los ua ib qho xim Doppler ultrasound ntshav ntws duab.Feem ntau muaj cov probes (phased array, linear array, convex array, mechanical fan scan, 4D probe, endoscopic probe, etc.), ultrasonic transmitter/receiver circuit, signal processing and image display.Siv tshuab ultrasound Doppler thiab lub hauv paus ntsiab lus ntawm ultrasound echo, peb Xim Doppler ultrasound tshuab ib txhij sau cov ntshav khiav, cov ntaub ntawv txav mus los thiab cov ntaub so ntswg tib neeg lub cev.
