Abstract:
1. An ultrasound imaging system, comprising: a transducer array, with an array of transducer elements, that transmits an ultrasound signal and receives a set of echoes generated in response to the ultrasound signal traversing a flowing structure; a beamformer that beamforms the set of echoes, generating a beamformed signal; a pre-processor that performs basebanding, averaging and decimation of the beamformed signal and determines an autocorrelation of the basebanded, averaged and decimated beamformed signal; and a velocity processor that generates an axial velocity component signal and a lateral velocity component signal based on the autocorrelation, wherein the axial and lateral velocity components indicate a direction and a speed of the flowing structure in the field of view.
