Figure 3
X-ray images at the middle of the rib recorded using synchrotron X-rays. (a), (b) and (c). Images recorded using synchrotron X-rays at Z ≃ 5 m. The refraction-contrast image of the trabecular bone with white–black contrast (→) on the film is shown in (b), the image of a small fracture with white–black–white contrast (→) on the film is shown in (c) (Mori, Shikano, Sato et al., 2000). (d) X-ray absorption-contrast image recorded using synchrotron radiation at Z ≃ 0 m. The rib sample without surrounding soft tissue packed in a transparent plastic bag was used for imaging. The sample has a small fracture in the middle. The fractures running horizontally and transversely are clearly seen in (a), and less so in (d). The trabecular bone, important in the diagnosis of bone diseases, was also clearly observed in (a). |
