Material decomposition using the PIXSCAN-FLI spectral micro-CT
Résumé
The advent of hybrid pixels, a technological breakthrough that makes possible to capture spectral information in X-ray tomography, paves the way to material decomposition and quantification. In this paper, a two-material decomposition approach based on a calibration step is implemented. We present the first results obtained exploiting real data acquired by the PIXSCAN-FLI, a spectral micro-CT scanner that is equipped with an in-house photon-counting detector. Separation of Aluminium and PMMA in a small animal phantom is shown
