Exploring 3D-structure analysis tools for a simulated bone remodelling process

Abstract

International audienceThe trabecular bone is a complex random network of interconnected rods and plates. Its trabecular structure is constantly remodelling to ensure a maintenance function. A simulated bone remodelling process was discussed in a previous study based on a BMU germ-grain model where type and orientation of local structure related to mechanical stress were not considered. In this study, we explore the potential ability of a 3D-skeleton coupled with a statistical tensor analysis to locally describe the trabecular structure for binary images. In order to add new constraints for BMU validation and BMU-shape characterisation in the simulator, we propose a strategy using inertia tensors based on the skeleton ensuring the feasibility of the entire process

Topological study of reservoir rocks and acidification processes using complex networks methods

“…[21][22] Networks have also been applied in the study of bone structure. [23][24][25][26] More recently, the work of van der Linden and A. Narsilio were able to correlate the measurement of the closeness centrality of pores in pore-throat networks to the permeability of the samples. 27 Even though the reduction of the volumetric data from µCT imaging to a network can be a powerful technique to acquire the main features of the porous structure, there is the question of what algorithm of network extraction should be used.…”
