Les images de notre quotidien du 21ème siècle sont acquises et visionnées en couleur. Nos télévisions, nos téléphones et ordinateurs, tous permettent une vision indirecte, de la scène à l’œil en passant par un système de d’acquisition

The detection of primordial B-mode polarization in the cosmic microwave background is one of the main targets for observational cosmology today. Their detection would constrain cosmic inflation models, an accelerating expansion phase occurring at the

Purpose: left atrial appendage (LAA) thrombus embolization is the main cause of vascular cerebral event in patients with atrial fibrillation, and a contraindication of percutaneous ablation. A CT scan is performed before procedure to search for throm

Spectral photon-counting CT (sCT) appeared recently as a new imaging technique presenting fundamental advantages with respect to conventional CT and duel-energy CT. However, due to the reduced number of photons in each energy bin of sCT and various a

Spectral optical imaging refers to the formation of images using several wavelengths of the light spectrum. This technique can be applied to biological tissues to quantify intrinsic markers. In this thesis, two biomedical applications have been inves

Material decomposition is a fundamental and primordial problem in spectral photon-counting X-ray CT (sCT). The present thesis focuses on the development of material decomposition methods using spectral and morphological information embedded in multi-

Scattered radiation is a major cause of bias, loss of contrast and artifacts in x-ray computed tomography (CT). Many correction methods have been proposed for conventional CT (using energy-integrating detectors) but it is still an open research topic

Spectral tomodensitometry is a new emerging x-ray imaging modality. If the dual-energy principle was already known for quite some time, new developments on photon-counting detectors now allowing acquiring more energy bins than before. This modality a
