Abstract

Osteons are longitudinally arranged cylindrical structures, which form the structural units of cortical bone. Cortical bone remodeling is closely related to the osteonal organization as newly formed osteons continuously replace older ones. The degree of mineralization in these new osteons is initially lower than in the existing bone as it takes time before osteons mature. Synchrotron radiation-based computed microtomography (μCT) and scanning acoustic microscopy (SAM) are two techniques, which have both sufficient spatial resolution and sensitivity to detect local variations in bone density. The aim of this study was therefore to compare both techniques for the analysis of osteonal mineraliz..
