概要	Micro-computed tomography (microCT) morphometry quantifies 3D bone and tissue architecture at micrometer resolution, enabling detailed assessment of bone density, trabecular structure, and porosity. Developed by Feldkamp and colleagues and standardized by the American Society for Bone and Mineral Research, microCT is the gold standard for preclinical bone analysis and has expanded to tissue engineering and material characterization.	Finite element analysis (FEA) for bone remodeling predicts how bone tissue density and architecture adapt to changes in mechanical loading over time. Pioneered by Rik Huiskes and Donald Carter in the 1980s, this computational approach integrates stress analysis with biophysical remodeling rules to simulate the long-term response of bone to disease, aging, or surgical intervention.	Scaffold porosity analysis characterizes the pore structure of tissue engineering scaffolds, including total porosity, pore size distribution, pore shape, and pore interconnectivity. Essential for predicting cell seeding, nutrient diffusion, and mechanical properties, this quantitative approach bridges scaffold design and biological performance.
