由于人体组织的各向异性，超声成像中存在相位偏差。相差制约了超声成像分辨率的进一步提高。互相关及其类似相位估计技术可以用于相差校正，ｊｉｔｔｅｒ是此类算法的基本限制。并行自适应接收补偿算法可以校正较小的相差，结合互相关技术能够得到比较理想的相差校正效果。
Due to the anisotropy of human tissue, there is phase deviation in ultrasound imaging. The difference restricts the further improvement of the resolution of ultrasound imaging. Cross-correlation and similar phase estimation techniques can be used for phase difference correction, which is the basic limitation of such algorithms. Parallel adaptive receive compensation algorithm can correct small phase difference, combined with cross-correlation technique can get the ideal phase difference correction effect.
