本文研究了组织中存在的规则间隔可分辨相干散射体之间的散射体间距的检测和估计问题。该参数已成功地用于组织结构分类、区分正常肝脏和肝硬化以及检测弥漫性肝病。本文提出了一种将射频场分解为扩散分量和相干分量的方法，由此可以很容易地计算出散射间距的最大似然估计（MLE）或最小均方误差（MMSE）估计。
This paper deals with the problem of detecting and estimating the scatterer spacing between the regularly-spaced resolvable coherent scatterers found in tissue. This parameter has been successfully used in classifying tissue structure, in differentiating between normal and cirrhotic liver, and in detecting diffuse liver disease. This paper presents a Wold decomposition of the radio frequency (RF) field into its diffused and coherent components from which maximum likelihood estimates (MLE) or minimum mean square error (MMSE) estimates of the scattering spacing is easily computed.
