Color Doppler ultrasound e masani lava ona fa'aogaina tekinolosi autocorrelation mo le fa'agasologa o faailoilo Doppler. O le faailo o le tafe o le toto e maua mai i tekinolosi autocorrelation e lanu-coded ma faʻapipiʻiina i luga o se ata e lua-dimensional i le taimi moni e fausia ai se lanu Doppler ultrasound ata tafe toto. E masani ona aofia ai suʻesuʻega (faʻasologa faʻasolosolo, laina laina, laina faʻapipiʻi, faʻataʻitaʻiga faʻainisinia, suʻesuʻega 4D, suʻesuʻega endoscopic, ma isi mea), eletise eletise / faʻafeiloaʻi eletise, faʻasologa o faailo ma faʻaaliga ata. Fa'aaogāina ole tekinolosi ole ultrasound Doppler ma le fa'avae ole ultrasound echo, tatou O le masini ultrasound Color Doppler e aoina i le taimi lava e tasi le tafega o le toto, faʻamatalaga o le gaioiga o le tino ma le ata o le tino o le tagata.
