Standard Doppler ultrasound investigations are limited to detect the axial blood velocity component, as they cannot directly estimate the flow direction. A typical approach for obtaining velocity vectors consists in combining the Doppler shifts detected by receiving the echoes from two (or more) different directions. Together with plane wave transmission, this strategy can assess the velocity data...
Standard Doppler ultrasound investigations are limited to detect the axial blood velocity component, as they cannot directly estimate the flow direction. A typical approach for obtaining a 2D velocity vector consists in combining the echoes received from two PW lines investigating the region of interest (ROI) from different angles. The estimate is usually limited to the sample volume where the focused...
