Figure 4
SR imaging of MCG and line profile analysis. PCI (b) showed the MCG more clearly than ACI (a). Line profile analyses of (a) and (b) are shown in (c) and (d), respectively. The gray values along the blue lines are displayed. Note that the MCG caused a distinct change in intensity (d) on the phase contrast image. The images were obtained with an SDD of 1 cm (a) and 30 cm (b). The pixel size was 1.625 µm × 1.625 µm, and the exposure time was 4 s. |
