    医学超声图像常受到非均匀性伪影的影响，使图像的局部统计特性发生变化，严重影响了超声图像的精确性。论文采用同态滤波方法消除非均匀性伪影，并通过仿真验证了该方法去除非均匀伪影的优势。

    Artifacts' local statistical features of the image changes ,seriously affect the accuracy of ultrasound images . Traditional methods cannot eliminate inhomogeneity artifact in the image ,thus the method of homomorphic filtering to elimi-nate inhomogeneity artifact is put forword .This method is verified by the simulation to have the advantages of uniform arti-facts .
