肌束方向是力学分析、临床诊断和康复评估中量化肌肉功能最广泛使用的参数之一。超声检查是一种非侵入性地测量人体肌肉肌束方向变化的可靠方法。传统上，大多数这样的测量是通过对超声图像的手动分析来进行的。这种手动方法耗时，主观，不适合测量动态变化。在这项研究中，我们开发了一种自动跟踪方法的基础上频域Radon变换。该研究的目的是通过将其与手动方法进行比较并确定其重复性来评价所提出的方法的性能。一个实时B型超声扫描仪被用来检查内侧腓肠肌收缩期间。多重相关系数（CMC）用于量化两种方法之间的一致性水平和拟定方法的重复性。通过线性回归和Bland-Altman分析对两种方法进行了比较。结果表明，使用所提出的方法获得的结果与使用手动方法获得的结果（CMC = 0.94 ± 0.03，差异=-0.23 ± 0.68°）一致，并且具有高度的可重复性（CMC = 0.91 ± 0.04）。总之，这里提出的新方法可以提供一个准确的，高度可重复的，和有效的方法来估计在肌肉收缩时的肌束方向。
Fascicle orientation is one of the most widely used parameters for quantifying muscle function in mechanical analysis, clinical diagnosis, and rehabilitation assessment. Ultrasonography has frequently been used as a reliable way to measure the changes in fascicle orientation of human muscles non-invasively. Conventionally, most such measurements are conducted by a manual analysis of ultrasound images. This manual approach is time consuming, subjective and not suitable for measuring dynamic changes. In this study, we developed an automated tracking method based on a frequency domain Radon transform. The goal of the study was to evaluate the performance of the proposed method by comparing it with the manual approach and by determining its repeatability. A real-time B-mode ultrasound scanner was used to examine the medial gastrocnemius muscle during contraction. The coefficient of multiple correlation (CMC) was used to quantify the level of agreement between the two methods and the repeatability of the proposed method. The two methods were also compared by linear regression and a Bland–Altman analysis. The findings indicated that the results obtained using the proposed method were in good agreement with those obtained using the manual approach (CMC = 0.94 ± 0.03, difference = −0.23 ± 0.68°) and were highly repeatable (CMC = 0.91 ± 0.04). In conclusion, the new method presented here may provide an accurate, highly repeatable, and efficient approach for estimating fascicle orientation during muscle contraction.
