FIG. 9. — Precision of μCT scan in detection of scaffold imperfections. (A) 3D rendering of a high-resolution scan of a 20-125-6x2L scaffold showing partial fusion between two overlying fibers (black arrows). (B) A SEM image of 20-125-2x5L scaffold showing the same partial melting effect (white arrows); scale bar is 10 μm. It was practically hard to tilt a 20-125-6x2L scaffold sufficiently in an SEM to visualize such a fiber fusion effect. (C) A screenshot of Supplementary Video S1 depicting the local thickness map of the scaffold, while (D) shows another screenshot in the video where the scaffold fibers are removed (shown in black) to visualize the pores. 3D, three-dimensional. Color images are available online.
