    • Embodiments for adaptively performing clutter filtering upon in an ultrasound system are disclosed. In one embodiment, the ultrasound system includes: an ultrasound data acquisition unit configured to transmit ultrasound signals to a target object and receive ultrasound echoes reflected from the target object to thereby acquire ultrasound data; and a processing unit configured to form a Doppler signal corresponding to each of a plurality of pixels constructing a Doppler mode image based on the ultrasound data, as well as to adjust coefficients of a clutter filter based on characteristics of the Doppler signal for each of the pixels for performing clutter filtering upon the Doppler signal.

    • Embodiments for filtering clutter signal from Doppler signal in an ultrasound system are disclosed. In one embodiment, a Doppler signal acquiring unit may transmit and receive ultrasound signals to and from a target object to acquire Doppler signal. A signal processing unit performs filtering upon the Doppler signal by using a first clutter filter having a first cutoff frequency and compute an input signal power to filtered input signal power rate (IFR) for the Doppler signal. The signal processing unit is further configured to be responsive to the IFR to modulate the Doppler signal and perform filtering upon the modulated Doppler signal by using the first clutter filter or to perform filtering the Doppler signal by using a second clutter filter having a second cutoff frequency.
    • 公开了用于在超声系统中从多普勒信号滤波杂波信号的实施例。 在一个实施例中,多普勒信号获取单元可以向目标对象发送和从目标对象接收超声信号以获取多普勒信号。 信号处理单元通过使用具有第一截止频率的第一杂波滤波器对多普勒信号进行滤波,并计算用于多普勒信号的滤波输入信号功率(IFR)的输入信号功率。 信号处理单元还被配置为响应于IFR来调制多普勒信号并且通过使用第一杂波滤波器对调制的多普勒信号执行滤波,或者通过使用具有第二截止频率的第二杂波滤波器对多普勒信号进行滤波 。
