    Abstract

    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.
