(A) Micro-CT images of different groups at 6 and 12 weeks, and the yellow color component was newly formed bone in these scaffolds. The upper left of each small picture is a cross-sectional image through the center of the scaffold. The upper right is the image along the longitudinal axis of the scaffold through the center of the scaffold, parallel to the coronal plane of the rabbit. The lower left is the image along the longitudinal axis of scaffold, parallel to the sagittal plane of the rabbit. The upper right picture is a three-dimensional image of porous scaffold material. (B) Fluorescence labeling images of newly formed bone (yellow, tetracycline; green, calcein). Scale bar: 100 μm. (C) Percentages of regenerated bone volume/total volume (BV/TV) in these groups. (D) Statistical analysis of bone mineralization rate in all groups. *p < 0.05 vs. pTi, #p < 0.05 vs. BaTiO₃/pTi, +p < 0.05 vs. pTi + LIPUS.
