Visualization of air artifacts in a PCCT scan of a FFPE tissue block of a rat lung. (a) A 3D chunk of FFPE lung tissue where artifacts due to trapped air bubbles are clearly visible. (b) The same chunk as in (a) with a threshold higher than the intensity of paraffin. The visualization reveals the 3D structure of the air artifacts and illustrates the 2D view of the air artifacts with the two marked regions (red rectangle). |
