A fast clutter rejection method for ultrasound color flow imaging is proposed based on the first-order perturbation as an efficient implementation of eigen-decomposition. The proposed method is verified by simulated data. Results show that the proposed method can be adaptive to non-stationary clutter movements and its computational complexity is lower than that of the conventional eigen-based clutter rejection methods.
提出了一种基于一阶微扰的超声彩色血流成像快速杂波抑制方法,作为特征分解的有效实现。通过仿真数据验证了该方法的有效性。结果表明,该方法能够自适应于非平稳的杂波运动,且其计算复杂度低于传统基于特征的杂波抑制方法。
