long-bone-diaphyseal-CSG-Toolkit

long-bone-diaphyseal-CSG-Toolkit computes diaphyseal cross-sectional geometric properties from high-resolution 3D bone models (humerus, femur, tibia) to support studies of bone adaptation to mechanical loading in biological anthropology and biomechanics.

Key Features:

• Implementation: GNU Octave-based computational toolkit for analysis of long-bone diaphyseal geometry.
• 3D model integration: Directly processes data from laser scanning and photogrammetry to compute cross-sectional geometric properties.
• Automated analysis: Supports single-bone and batch-processing modes for automated computation of diaphyseal metrics.
• Graphical representation: Produces graphical outputs of periosteal contours and associated cross-sectional geometric properties.
• Advanced optimization algorithms: Applies orientation algorithms to align cross-sectional contours anatomically and reduce intra- and inter-observer error.

Scientific Applications:

• Bone adaptation studies: Quantifies structural responses of diaphyses to mechanical loading for analyses of bone functional adaptation.
• Evolutionary biology: Compares diaphyseal geometry to investigate morphological adaptations across populations or taxa.
• Biomechanical performance assessment: Derives cross-sectional metrics relevant to load-bearing capacity and mechanical behavior.
• Pathology investigation: Identifies and compares structural alterations in bones affected by pathological conditions.
• Anthropological and clinical geometry: Provides precise geometric data from 3D models for anthropological research and clinical analyses.

Methodology:

Implemented in GNU Octave, the toolkit computes cross-sectional geometric properties from high-resolution 3D scans or photogrammetric models and applies optimization algorithms to orient periosteal cross-sectional contours anatomically.
