抽象。准确测量肌腱和韧带的横截面积对于确定生物样本的力学性能至关重要。我们测量这些横截面积在体外兔标本，使用超声，以评估这种方法作为一种非接触式测量技术的实用性。采用超声、数字卡尺和计算机图像分析技术测量了兔跟腱、内侧副韧带（MCL）和前交叉韧带（ACL）的横截面积。对于这三种软组织中的每一种，数字卡尺和超声检查获得的值之间具有高度相关性，并且这三种方法获得的值没有显著差异。超声波检查可以检测到标本表面的凹陷，如ACL，因为标本的横向超声图的形状类似于其在照片上的横截面形状。我们的结论是，超声检查产生的值是可以接受的，超声检查是一种有用的非接触式测量技术。
Abstract. Accurate measurement of the cross-sectional area of tendons and ligaments is essential in determining the mechanical properties of biological specimens. We measured these cross-sectional areas in rabbit specimens in vitro, using ultrasonography, in order to evaluate the usefulness of this method as a noncontact measurement technique. The cross-sectional areas of a rabbit's Achilles tendon, medial collateral ligament (MCL), and anterior cruciate ligament (ACL) were measured by means of ultrasonography, digital calipers, and computerized image analysis. For each of these three soft tissues, there was a high correlation between the values yielded by digital calipers and ultrasonography, and there was no significant difference in the values obtained by these three methods. Ultrasonography can detect the concavities on the surface of a specimen such as the ACL, because the shape of the specimen's transverse sonogram resembles its cross-sectional shape on a photograph. We concluded that the values yielded by ultrasonography were acceptable, and that ultrasonography is a useful noncontact measurement technique.
