FIG. 8.

Schematic illustrating the relationship between (a) % interconnectivity plotted against virtual object diameter, d, and (b) d plotted against L^−1/0.88, where L is the maximum accessible distance to an object of diameter d. In Region 1, L is larger than the Micro-CT dataset; therefore, the pore space appears fully interconnected. In Region 2, L approaches the dataset size, producing dramatic changes in % interconnectivity according to virtual object diameter, until Region 3, where only the pores at the scaffold surface are accessible. As shown in (b), measurements from Region 2 can be used to identify the largest object diameter that can travel through the entire scaffold even at infinite length scales: the percolation diameter, d_c.
