La tomographie est une technique permettant de reconstruire une carte des propriétés physiques de l'intérieur d'un objet, à partir d'un ensemble de mesures extérieures. Bien que la tomographie soit une technologie mature, la plupart des algorithmes utilisés dans les produits commerciaux sont basés sur des méthodes analytiques telles que la rétroprojection filtrée. L'idée principale de cette thèse est d'exploiter les dernières avancées dans le domaine de l'informatique et des mathématiques appliqués en vue d'étudier, concevoir et implémenter de nouveaux algorithmes dédiés à la reconstruction 3D en géométrie conique. Nos travaux ciblent des scenarii d'intérêt clinique tels que les acquisitions faible dose ou faible nombre de vues provenant de...
