The developmental goal of 3D ultrasound imaging (3DUS) is to engineer a modality to perform 3D morphological ultrasound analysis of human muscles. 3DUS images are constructed from calibrated freehand 2D B-mode ultrasound images, which are positioned into a voxel array. Ultrasound (US) imaging allows quantification of muscle size, fascicle length, and angle of pennation. These morphological variables are important determinants of muscle force and length range of force exertion. The presented protocol describes an approach to determine volume and fascicle length of m. vastus lateralis and m. gastrocnemius medialis. 3DUS facilitates standardization using 3D anatomical references. This approach provides a fast and cost-effective approach for quantifying 3D morphology in skeletal muscles. In healthcare and sports, information on the morphometry of muscles is very valuable in diagnostics and/or follow-up evaluations after treatment or training.
三维超声成像（3DUS）的发展目标是设计一种能够对人体肌肉进行三维形态超声分析的方法。三维超声图像由经校准的徒手二维B型超声图像构建而成，并被定位到体素阵列中。超声（US）成像能够对肌肉大小、肌束长度和羽状角进行量化。这些形态学变量是肌肉力量和力施加长度范围的重要决定因素。本文介绍的方案描述了一种确定股外侧肌和腓肠肌内侧头肌体积和肌束长度的方法。三维超声有助于使用三维解剖学参考进行标准化。这种方法为量化骨骼肌的三维形态提供了一种快速且经济高效的途径。在医疗保健和体育领域，肌肉形态测量信息在治疗或训练后的诊断和/或随访评估中非常有价值。
