Multi-Material Discrimination Using Photon Counting Spectral Computed Tomography
Quantitative volumetric mapping of multiple materials with spectral computed tomography (CT) has applications in many areas including biomedical imaging, defense and security, geophysical imaging of rock composition and in materials and chemical imaging. Dual or multi-kVp x-ray exposure when using …

Low dimensionality spectral sensing for low cost material discrimination and identification
Spectroscopy is a powerful tool in material identification, characterization and discrimination. Unfortunately industrial and laboratory spectrometers are typically very large, costly, and inconvenient. The aim of this thesis is to broaden the awareness and appeal of spectroscopic sensing …
