Conventional ultrasonic motion or flow velocity estimation is limited to the axial velocity component. A novel technique, called "spatial quadrature," for the simultaneous estimation of axial and lateral velocity components is introduced. This technique utilizes even and odd spatial weightings of the point spread function that have a quandrature relationship. These weightings produce modulation in the received echo that can be decoded to quantify lateral motion. This estimator can be… CONTINUE READING
