The quantification of muscle volume can be used to estimate muscular strength. Therefore, we developed a flexible measuring system for muscle volume using ultrasonog-raphy. In the measuring process, subjects are not required to perform any muscular contraction, so it is completely safe and particularly suitable for elderly people. The ultrasound probe is installed on a mechanical arm, and continuously scans fragmental images along the body surface. The measured images are then composed into a wide area cross-sectional image. However, the muscle area measured by our system was slightly smaller than that measured by MRI. because the ultrasound probe contacted the body surface with a little pressure during the measurement. The strain then decreases the total image size and its circumference. This paper introduces our developed system and proposes a new calibration method for the muscle area in the thigh based on its circumference.
肌肉体积的量化可用于估计肌肉力量。因此，我们开发了一种使用超声成像的灵活肌肉体积测量系统。在测量过程中，受试者无需进行任何肌肉收缩，因此完全安全，特别适合老年人。超声探头安装在机械臂上，并沿着身体表面连续扫描碎片图像。然后将测量的图像组合成一个大面积的横截面图像。然而，我们系统测量的肌肉面积略小于MRI测量的面积。因为在测量过程中超声探头以轻微压力接触身体表面。这种应变会减小图像的整体尺寸及其周长。本文介绍了我们开发的系统，并基于大腿周长提出了一种新的大腿肌肉面积校准方法。
