对生物结构（如骨骼）的变形进行全场测量是研究力学行为空间异质性的一种很有前途的实验方法。随着高分辨率三维成像技术的出现，数字体积相关（DVC）允许测量整个体积的空间异质性三维变形场。对于像椎骨这样的骨骼，使用DVC来检测衰竭的发生和进展与骨质疏松性骨折的研究直接相关。与骨组织的机加工样本相反，将DVC应用于整个骨骼涉及额外的挑战，例如不规则的几何形状、大数据集和降低的信噪比。这些挑战在本文中得到解决，并DVC方法的结果是用来检查屈服和屈服后变形的椎体压缩实验。
Full-field measurement of deformation in biological structures such as bones is a promising experimental approach for study of the spatial heterogeneity in mechanical behavior. With the advent of high-resolution, 3-D imaging, digital volume correlation (DVC) allows for the measurement of spatially heterogeneous, 3-D deformation fields throughout entire volumes. For bones such as the vertebra, use of DVC to detect the onset and progression of failure is of direct relevance to the study of osteoporotic fractures. Application of DVC to whole bones, as opposed to machined specimens of bone tissue, involves additional challenges such as the irregular geometry, large data sets, and decreased signal-to-noise ratio. These challenges are addressed in this paper, and the DVC method that results is used to examine yield and post-yield deformations in vertebral compression experiments.
