The patch structural feature assessment using PCI-CT imaging based on the combined effect of the reduced ROI (3 mm2) at tomography projections of 3000 (a), 1500 (b), 1000 (c) and 750 (d) to quantitatively evaluate the size of strands and pores from the apparent refractive index profiles (e–h) associated with the dashed lines on the patch images. |
