    • 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.
    • 公开了一种用于在超声系统中设置来自多普勒信号的杂波信号滤波的特征向量的实施例。 在一个实施例中,超声系统包括:多普勒信号获取单元,被配置为向目标对象发送和从目标对象接收超声信号以获取第一多普勒信号; 以及处理单元,被配置为通过使用所述第一多普勒信号来计算多个特征向量,并且形成对应于所计算的特征向量的方向的第二多普勒信号,所述处理单元还被配置为计算所述第二多普勒信号的分量值并且设置用于杂波的特征向量 通过使用所计算的分量值在多个特征向量之间进行信号滤波。
