Generation of 3D shape, density, cortical thickness and finite element mesh of proximal femur from a DXA image.
TL;DR: DXA-based FE simulation was able to explain 85% of the CT-predicted strength of the femur in stance loading, and the present method can be used to accurately reconstruct the 3D shape and internal density of the Femur from 2D DXA images.

TL;DR: The ShapeWorks software includes extensions to the basic PBM optimization to construct joint models of multiple anatomical shapes, regression models, and to specify surface boundaries on shapes, such as cutting planes, as well as software for visualization and analysis of correspondence models.

3D-DXA: Assessing the Femoral Shape, the Trabecular Macrostructure and the Cortex in 3D from DXA images
Ludovic Humbert,Yves Martelli,Roger Fonolla,Martin Steghofer,Silvana Di Gregorio,Jorge Malouf,Jordi Romera,Luis Miguel del Río Barquero +7 more
TL;DR: 3D-DXA provides a detailed analysis of the proximal femur, including a separate assessment of the cortical layer and trabecular macrostructure, which could potentially improve osteoporosis management while maintaining DXA as the standard routine modality.

Review of 2-D/3-D Reconstruction Using Statistical Shape and Intensity Models and X-Ray Image Synthesis: Toward a Unified Framework
Cornelius Johannes Frederik Reyneke,Marcel Lüthi,Valérie Burdin,Tania S. Douglas,Thomas Vetter,Tinashe Mutsvangwa +5 more
TL;DR: A unified mathematical formulation of the problem is proposed in a common conceptual framework, using unambiguous terminology, and a large number of state-of-the-art 2-D/3-D bone reconstruction methods are proposed in an iterative, non-rigid, intensity-based approach.

Update on Imaging-Based Measurement of Bone Mineral Density and Quality.
TL;DR: While there are limitations, DXA remains the standard technique to measure density in patients with rheumatological disorders, and newer modalities to measure bone quality may allow better characterization of bone fragility but currently are not standard of care procedures.

Active appearance models
Abstract: We describe a new method of matching statistical models of appearance to images. A set of model parameters control modes of shape and gray-level variation learned from a training set. We construct an efficient iterative matching algorithm by learning the relationship between perturbations in the model parameters and the induced image errors.

TL;DR: A novel method of interpreting images using an Active Appearance Model (AAM), a statistical model of the shape and grey-level appearance of the object of interest which can generalise to almost any valid example.
Principal warps: thin-plate splines and the decomposition of deformations
TL;DR: The decomposition of deformations by principal warps is demonstrated and the method is extended to deal with curving edges between landmarks to aid the extraction of features for analysis, comparison, and diagnosis of biological and medical images.

The diagnosis of osteoporosis
TL;DR: This paper summarizes issues and proposes diagnostic criteria for osteoporosis for practical use and addresses a number of problems which need to be addressed in adapting a conceptual definition for clinical use.

Generalized procrustes analysis
TL;DR: In this article, the authors investigated the problem of translating, rotating, reflecting and scaling configurations to minimize the goodness-of-fit criterion, where Gi is the centroid of the points in p-dimensional space.
