| Abstract Scope |
X-ray computed tomography has evolved to be a standard characterization method for all types of materials. Using the method, detailed structural information down to micrometer-scale resolution is obtained, and the position or distribution of different materials in samples can be derived. However, the method does not provide any absolute elemental information, or can fall short when the difference in atomic number between components is limited. In this work, we present the introduction of spectral CT to provide elemental information from any point inside a sample, in a non-destructive manner. Using spectral CT, contrast can be generated in materials that look the same using conventional micro-CT or unknown elements can be identified in these samples. Spectral CT revolutionizes micro-CT imaging, by providing a new dimension to X-ray imaging, in fields such as polymer research, mineralogy, mining and many more. |
