[en] First introduction to the field of (emission and transmission) tomography reconstruction : general principles, sinogram concept, backprojection operation, Radon transform, 2D and 3D analytic reconstruction, filtered backprojection, Feldkamp algorithm, iterative methods, algebraic and statistical approaches (Gauss and Poisson noise), 3D to 2D reduction. Full demonstration of most algorithms presented in the book are provided. [fr] Cet ouvrage présente une première approche des concepts et des méthodes de la reconstruction en tomographie d'émission et de transmission : principes généraux, structure des données tomographiques (sinogramme), reconstruction analytique en deux dimensions (2D), algorithme de rétroprojection filtrée, problématique de la reconstruction en tomographie 3D,
algorithme de Feldkamp pour la tomographie 3D en géométrie conique, méthodes itératives algébriques ou statistiques avec bruit gaussien ou poissonien, réduction du problème de la reconstruction 3D en problèmes de reconstruction 2D. L'ouvrage se termine par une série d'annexes où figurent les démonstrations des algorithmes de reconstruction exposés tout au long du texte.
