立体摄影成像和数字图像相关性被用来确定乳房皮肤变形的受试者的方向从仰卧到直立的变化。受试者的姿势从仰卧到直立的变化可能会导致乳房皮肤的某些部分发生显着拉伸。皮肤的最大主拉伸比在不同的对象中是不同的,并且在1.25-1.60的范围内变化。还发现乳房的边界相对于骨骼结构和其他固定点(如胸骨切迹)显著移动。这种测量是至关重要的,因为它们提供了基于有限元公式的生物力学乳房模型的验证的基本数据。
Stereophotographic imaging and digital image correlation are used to determine the variation of breast skin deformation as the subject orientation is altered from supine to upright. A change in subject’s position from supine to upright can result in significant stretches in some parts of the breast skin. The maximum of the major principal stretch ratio of the skin is different in different subjects and varies in the range of 1.25–1.60. It is also found that the boundaries of the breast move significantly relative to the skeletal structure and other fixed points such as the sternal notch. Such measurements are crucial since they provide basic data for validation of biomechanical breast models based on finite element formulations.
