More Information
Summary:Embodiments for setting eigenvectors for clutter signal filtering from Doppler signals in an ultrasound system are disclosed. In one embodiment, the ultrasound system includes: a Doppler signal acquisition unit configured to transmit and receive ultrasound signals to and from a target object to acquire first Doppler signals; and a processing unit configured to compute a plurality of eigenvectors by using the first Doppler signals and form second Doppler signals corresponding to directions of the computed eigenvectors, the processing unit being further configured to compute component values of the second Doppler signals and set eigenvectors for clutter signal filtering among the plurality of eigenvectors by using the computed component values.
