生物材料典型的错综复杂的层次化微结构产生了各向异性机械性能的迷人组合，可以超过人造材料。三维(3D)成像技术的结合有可能以前所未有的细节揭示这些结构。然而，只有当结构和力学性能之间的关系能够被阐明时，才能达到完全的理解。X射线计算机层析成像(CT)是一种独特的方法，可以在大范围的长度尺度上对这种结构进行成像。我们回顾了导致对比度和空间分辨率提高的最新技术进步。我们重点介绍了延时CT 3D研究如何跟踪分层微结构对机械载荷的响应。
The intricate hierarchical microstructures typical of biological materials give rise to fascinating combinations of anisotropic mechanical properties that can surpass those of man-made materials. The linking together of three-dimensional (3D) imaging techniques has the potential to reveal these structures in unprecedented detail. However, a complete understanding can only be reached if the relationship between structure and mechanical properties can be elucidated. X-ray-computed tomography (CT) is uniquely placed to image such structures across a wide range of length scales. We review recent technical advances that are leading to improved contrast and spatial resolution. We highlight how time-lapse CT 3D studies can track the response of hierarchical microstructures to mechanical loading.
