Abstract Scope |
Micro-CT can be used to study the structure of samples from a centimeter to micrometer scale. One of the main limitations in this, however, is the inability to perform true material identification without prior knowledge, as contrast inside a micro-CT scan is mainly caused by the atomic number of the sample.
To overcome this limitation, we present the integration of an energy-sensitive spectral detector inside laboratory-based micro-CT scanners. Using this type of detector, not only the attenuated intensity of the X-ray beam when travelling through samples could be measured, but the entire energy spectrum (20-160 keV) of the X-ray beam was measured. Measurements were performed on various types of samples, from simple plastic specimen as proof of concept to economically important samples such as batteries and raw materials for the mining industry. |
