Quantitative x-ray radiology using the absorption and scattering information |
| abstract |
The present invention proposes a quantitative radiographic method using X-ray imaging. This invention uses the ratio of the absorption signal and the (small-angle) scattering signal (or vice-versa) of the object as a signature for the materials. The ratio image (dubbed R image) is independent from the thickness of the object in a wide sense, and therefore can be used to discriminate materials in a radiographic approach. This invention can be applied to imaging systems, which can record these two signals from the underlying object (for instance, an X-ray grating interferometer). Possible applications of the suggested invention could be in material science, non-destructive testing and medical imaging. Specifically in this patent, we illustrate how this invention can be used to estimate the volumetric breast density. The use of the R image and the corresponding algorithm are also presented hereafter. |
