TLDR
This research is an animal study based on the perfusion of vascularization by a contrast agent (a mixture of 50% barium sulfate with 1.5% of gelatin) before euthanasia to understand simultaneously the bone microarchitecture and its vascular microarch architecture.Abstract:
Trabecular bone and its microarchitecture are of prime importance for health. Studying vascularization helps to better know the relationship between bone and vascular microarchitecture. This research is an animal study (nine Lewis rats), based on the perfusion of vascularization by a contrast agent (a mixture of 50% barium sulfate with 1.5% of gelatin) before euthanasia. The samples were studied by micro CT at a resolution of 9μm. Softwares were used to show 3D volumes of bone and vessels, to calculate bone and vessels microarchitecture parameters. This study aims to understand simultaneously the bone microarchitecture and its vascular microarchitecture.read more

Mojette tomographic reconstruction for micro-CT: a bone and vessels quality evaluation
H. Der Sarkissian,Benoit Recur,Jp. Guédon,Pauline Bléry,Pauline Bléry,Paul Pilet,Yves Amouriq,Yves Amouriq +7 more
TL;DR: The goal of this paper is to challenge the proposed Mojette discrete reconstruction scheme from real micro-CT data, which represents a modality where the quality of CT reconstruction is very high thanks to the acquisition properties.

Bone vascularization and bone micro-architecture characterizations according to the μCT resolution
E. Crauste,E. Crauste,Florent Autrusseau,Jean-Pierre Guédon,Paul Pilet,Yves Amouriq,Yves Amouriq,Pierre Weiss,Bernard Giumelli +8 more
TL;DR: In this paper, the authors investigated the relationship between bone and vessels and proposed some indices of characterization for the vessels issued from those used for the bone and found that the largest portions of the vascular tree are orthogonal to the obtained slices of the bone.

Linking bone microarchitecture to projections texture analysis
TL;DR: This paper focuses onto the relationship between bone microarchitecture and the texture found on micro CT projections from a small animal study, and determines the texture orientation onto a ROI region of both medial epiphysis and diaphisys using a local variance computed onto Mojette projections from the ROI.

SURF: speeded up robust features
TL;DR: A novel scale- and rotation-invariant interest point detector and descriptor, coined SURF (Speeded Up Robust Features), which approximates or even outperforms previously proposed schemes with respect to repeatability, distinctiveness, and robustness, yet can be computed and compared much faster.

TL;DR: A committee of the Society to develop a unified system of termnology, suitable for adoption by the Journal of Bone and Mineral Research as part of its Instructions to Authors is formed, and is as complex and conceptually difficult as the field with which it deals.

Three-dimensional methods for quantification of cancellous bone architecture
TL;DR: The different techniques for 3-D imaging, which include serial sectioning, X-ray tomographic methods, and NMR scanning, are reviewed, and it is argued that connectivity and architectural anisotropy (fabric) are of special interest in mechanics-architecture relations.
