Figure 4
Examples of LabDCT projections collected at the same rotation angle with different experimental parameters. The images shown are the result after division by the flat-field image, similar to Fig. 2(c). (a)–(d) are from data sets A, C, E and D2, respectively (see Table 1). The gray scale value used for visualization is the same for all the images. The scale bars used here are derived from the pixel size, as in Fig. 2. |
