              <p>L'objet de cette étude est la reconstruction tomographique d'objets ou d'organes qui se déforment au cours de l'acquisition des projections dans un scanner. Notre approche est celle de la compensation analytique des déformations lors de la reconstruction par adaptation des algorithmes de type FBP rapides et modernes (contexte de la reconstruction de ROI, Région d'Intérêt). Dans la thèse de Sébastien Roux, des compensations analytiques de déformations affines ont été établies. Nous proposons ici d'étendre ces résultats à des classes de déformations beaucoup plus vastes qui ne conservent que les droites de mesure (et pas nécessairement toutes les droites du plan).</p>
