    • 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.
    • 公开了在超声系统中自适应执行杂波滤波的实施例。 在一个实施例中,超声波系统包括:超声数据获取单元,被配置为将超声信号发射到目标对象并接收从目标对象反射的超声回波,从而获取超声数据; 以及处理单元,被配置为基于所述超声数据形成与构成多普勒模式图像的多个像素中的每一个相对应的多普勒信号,以及基于所述多普勒信号的特性来调整杂波滤波器的系数 用于对多普勒信号执行杂波滤波的像素。
