Dual-Energy Computed Tomography for Ceramics and Composite Materials
This work is part of the Brite-Euram project BRE5535 “DUALETO”, whose purpose is to set-up a Dual-Energy Computed Tomography (DE-CT) system suited for the examination of fibers-reinforced composites. DE measurements are obtained by a microfocus X-ray source, and a multi-wire proportional chamber which simultaneously collects projection data at two different energies over a section of the object .
