FIG. 8.

μ-CT images of implanted coated PLLA at 3 (a) and 10 (c) weeks, and implanted coated PCL at 3 (b) and 10 (d) weeks. R-squared values of correlation between amount of calcium (mg) from OCPC method and tissue mineral content (mg) from μ-CT data (e). Threshold values were varied from 400 to 800 HU by 50 HU, and the highest R-squared value (0.90) were achieved at threshold with 600 HU, as the relation shown (f ). The calcium amount and volume from μ-CT data were correlated strongly with R-squared value of 0.89 (g). Color images available online at www.liebertpub.com/tec
