Figure 3

Images of filtered back projection (FBP) at 10 (a), 25 (b), 50 (c), and 175 mAs (g) and True Fidelity Image (TFI) at 10 (d), 25 (e), and 50 mAs (f) of cadaveric lung (usual intestinal pneumonia). Window width was 1200 and Window level was − 700 (Hounsfield Unit). Scan field of view was 20 cm. The length and width of each figure was 6.5 cm. As tube current–time product decreased, the shape of the nodule (arrowhead) and bronchiectasis (arrow) at TFI and FBP varied slightly or were almost the same as that of 175 mAs-FBP.
