通过对肌腱回声频谱的分析，探讨了肌腱回声与电离角的强烈相关性。结合回声频谱和几种模式的高分辨率图像显示，束和束周围的流体空间可能是超声散射的来源。建立了肌腱结构的数学模型，解释了肌腱的各向异性微结构如何引起角度相关的回声。将自发性损伤的马腱样本的回声光谱与正常马腱进行比较，发现各向异性特性显著降低，这似乎与修复过程中产生的胶原的空间组织和类型有关。回声光谱随电离角的变化是机械损伤的一个强有力的指标。(电子邮件：wjhornof@ucdavis.edu)(C)2003年世界医学生物学超声联合会。
The strong dependence of tendon echogenicity on insonation angle is explored by analyzing echo spectra. Combining echo spectra with high-resolution images from several modalities reveals that fluid spaces surrounding fascicles and bundles are likely sources of ultrasonic scatter. Mathematical models of tendon structure are proposed to explain how the anisotropic microstructure of tendon gives rise to angle-dependent echogenicity. Echo spectra from spontaneously damaged equine tendon samples were compared with normal equine tendon and found to exhibit a dramatic decrease in anisotropic properties that appears to be related to the spatial organization and type of collagen generated during repair. Variation in echo spectra with insonation angle is a robust indicator of mechanical damage. (E-mail: wjhornof@ucdavis.edu) (C) 2003 World Federation for Ultrasound in Medicine Biology.
