彩色多普勒处理是超声成像系统中最重要的实用程序之一。彩色多普勒成像主要用于观察感兴趣区域的血流情况。杂波和散斑噪声会极大地影响期望的血液信号，有效消除这两种噪声是主要的设计问题。在这项工作中，我们提出了（1）联合决策杂波滤波器和（2）运动跟踪自适应持久性，分别用于有效消除杂波和散斑噪声。所提出的两个滤波器单独的性能比参考算法好2~3 dB，并且所提出的自适应杂波滤波器和持久性也可以在同一系统中一起工作以获得更好的性能。
Color Doppler processing is one of the most important utility in the ultrasound imaging systems. Color Doppler imaging is mainly used to observe the blood flow in the region of interest. The desired blood signal will be greatly affected by the clutter and speckle noises, and it is the major design issues to eliminate these two kinds of noises effectively. In this work, we proposed a (1) joint-decision clutter filter and (2) motion-tracking adaptive persistence for effectively eliminating the clutter and speckle noises, respectively. The proposed two filters have individually 2~3 dB better performance than the referenced algorithms, and the proposed adaptive clutter filter and persistence can also work together in the same system to obtain even better performances.
