Figure 4
Dose-compatible absorption and dark-field contrast image of test object 15 (0.50 mm-thick tumor-like mass). The tumor-like mass is clearly depicted in the dark-field image. A combination of the two contrast modalities leads to better tumor detectability using less than the conventional two-view mammography clinical dose (Boone et al., 2001). Both images have been scaled to their minimum and maximum pixel values. |
