Figures

Grahic Jump Location
Prediction of BV/TV calculated from 21/21 mm images by BV/TV calculated from other combinations of scan/reconstruction voxel size. All relationships are significant (Table 2).
Grahic Jump Location
Prediction of FE apparent modulus (E) calculated from 21/21 μm images by E calculated from other combinations of scan/reconstruction voxel size. All relationships except for 110/110 μm are significant (Table 2).
Grahic Jump Location
Prediction of the average trabecular von Mises stress (VMExp) calculated from 21/21 μm images by VMExp calculated from other combinations of scan/reconstruction voxel size. The 110/110 μm case is nonsignificant and the 50/110 μm case is only marginally significant (Table 2).
Grahic Jump Location
Prediction of the standard deviation of trabecular von Mises stress (VMSD) calculated from 21/21 μm images by VMSD calculated from other combinations of scan/reconstruction voxel size. All relationships are significant (Table 2).
Grahic Jump Location
Prediction of the coefficient of variation of trabecular von Mises stress (COV) calculated from 21/21 μm images by COV calculated from other combinations of scan/reconstruction voxel size. All relationships except for the 50/110 μm and 110/110 μm cases are significant (Table 2).
Grahic Jump Location
Prediction of the shear stress amplification (VMExp/σz) calculated from 21/21 μm images by VMExp/σz calculated from other combinations of scan/reconstruction voxel size. All relationships are significant (Table 2).
