评估软组织的力学性能需要准确测量横截面积。迄今为止，用于确定韧带和肌腱的横截面积的技术一直不太理想，这是由于组织的复杂几何形状以及它们在施加的外部载荷下容易变形的事实。本文提出了一种新的方法，即用平行激光束测量的图象重建技术来确定横截面积。使用该程序，还可以确定试样横截面的实际形状。结果被证明是高度准确的，这种方法不需要与试样的机械接触。
Assessment of the mechanical properties of soft tissues requires accurate measurement of the cross-sectional area. To date, techniques for determining cross-sectional areas of ligaments and tendons have been less than ideal due to the tissues'' complex geometries and the fact that they deform easily under an applied external load. A new procedure has been developed for determining the cross-sectional area by means of an image reconstruction technique based on measurements from collinated laser beams. Using this procedure, the actual shape of the specimen cross-section can also be determined. The results are demonstrated to be highly accurate, and this methodology does not require mechanical contact with the specimen.
