FIG. 4.

Plots of % interconnectivity against virtual object diameter, showing the effect of restricting the accessible surfaces of Micro-CT sub-volumes sampled from the scaffold fabricated with (a) 0.05 M acetic acid, or (b) 0.001 M HCl. This approach provides measurements of % interconnectivity, defined as the proportion of accessible pore space for a virtual object traveling from the outside of a 1 mm³ Micro-CT dataset, in specified directions as indicated in the schematic. Mean and standard error of the measurements from three different sub-volumes are displayed. Color images available online at www.liebertpub.com/tec
