Abstract
A new ultrasound Doppler technique for obtaining calibrated 3D flow velocity information is reported. Theoretical expressions are derived for the expected Doppla shift and the spectral spread under a variety of flow conditions. Experimental results using a revolv-) ing turntable demonstrated the linearity of velocity detection, the ability to resolve an arbitrary velocity vector, and conrimed the theoretical predictions of spectral spread.Keywords
