Adaptive clutter filtering in an ultrasound system

摘要

Embodiments for performing clutter filtering in an ultrasound system are disclosed. In one embodiment, an ultrasound data acquisition unit acquires ultrasound data from a target object for color Doppler imaging, and a processing unit extracts a plurality of frequency components of the ultrasound data using an autoregressive model and computes a mean frequency component of the plurality of frequency components. The processing unit detects frequency components corresponding to a clutter signal based on the plurality of frequency components and the mean frequency component and performs clutter filtering upon the ultrasound data by using the frequency components corresponding to the clutter signal.
