(a) Steps of compartmentation for the 3D micro-CT image of a femoral bone. Masking was performed to identify the bone marrow cavity including trabecular bone (TB). CB55 (55% of length) was digitally isolated. The total volume was determined, including CB, TB, and masked voxels. The TMD parameters were determined in individual TMD histograms of typical (b) whole bone, (c) CB, and (d) TB for sham and OVX groups.
