Abstract:
1. An ultrasound system, comprising: a Tx/Rx unit configured to transmit ultrasound signals to a target object and receive echoes reflected from the target object; a signal processing unit configured to process the received echoes to provide 2-dimensional image data of the target object, the 2-dimensional image data being representative of a 2-dimensional image; and an input unit configured to enable a user to set a region of interest (ROI) on the 2-dimensional image of the target object, wherein: the Tx/Rx unit and the signal processing unit are configured to operate such that a Doppler mode image pixel data corresponding to the ROI is obtained, and the signal processing unit is further configured to select a reference pixel from pixels within the ROI, compute a mean frequency of reference pixel signals corresponding to the reference pixel based on the Doppler mode image pixel data, set filter cutoff frequencies of a filter based on the computed mean frequency and filter the Doppler mode image pixel data with the set filter cutoff frequencies to output filtered pixel data with clutter signals filtered.
