We developed an innovative gel pad that covers the entire lower leg to remove artifacts due to the pressure of the transducer in freehand 3-dimensional ultrasonography. In comparison to the reference method in water, this study showed that this new method was valid (bias, 3.4 mL; limit of agreement, 7.7 mL for a volume of ≈220 mL) and reliable (coefficient of variation, <1.1%) for the measurement of gastrocnemius medialis muscle volume. Considering that it is easier to use than the water tank technique, it has much promise for volumetric measurement of many muscles.
我们研发了一种创新的凝胶垫，可覆盖整个小腿，以去除因自由式三维超声中换能器压力导致的伪影。与在水中的参考方法相比，本研究表明该新方法是有效的（偏差 3.4mL；约 220mL 体积时的协议范围限为 7.7mL），且用于测量比目鱼肌肌肉体积时具有可靠性（变异系数 <1.1%）。鉴于它比水箱技术更易于使用，因此它有望用于许多肌肉的体积测量。
