Optimized experimental conditions for extracting accurate information at subpixel length scales from analyzer-based X-ray imaging were obtained and applied to investigate bone regeneration by means of synthetic beta-TCP grafting materials in a rat calvaria model. The results showed a 30% growth in the particulate size due to bone ongrowth/ingrowth within the critical size defect over a 1-month healing period.
优化了基于分析仪的 X 射线成像中以亚像素长度尺度提取准确信息的实验条件，并将其应用于研究大鼠颅骨模型中合成 β-TCP 移植物材料的骨再生。结果表明，在 1 个月的愈合期内，由于临界尺寸缺陷内的骨长入/长入，颗粒尺寸增加了 30%。
