FIG. 6.

Yellow color indicates biomineral coatings on the scaffold surface by varying the threshold values of μ-CT from 200 to 1000 (a). R-squared values of correlation between amount of calcium (mg) from orthocresolphthalein complex-one (OCPC) method and tissue mineral content (mg) from μ-CT data (b). Threshold values were varied from 400 to 800 HU by 50 HU, and the highest R-squared value (0.96) at threshold value with 600 HU. The relation between calcium amount and Tissue mineral content (TMC) (c) and volume from μ-CT data (d) are also shown. The R-squared values between calcium amount and volume from μ-CT data (d) is 0.96. Color images available online at www.liebertpub.com/tec
