Publikováno v: International Journal of Biomedical Imaging, Vol 2006 (2006)

Cone-beam (CB) acquisition is increasingly used for truly three-dimensional X-ray computerized tomography (CT). However, tomographic reconstruction from data collected along a circular trajectory with the popular Feldkamp algorithm is known to produc

Generalization of FDK 3D tomographic reconstruction algorithm for an off-centered cone beam geometry

Autor: Françoise Peyrin, S. Valton, Dominique Sappey-Marinier

Publikováno v: ICIP (3)

3D reconstruction from 2D cone beam projections obtained along a single circular x-ray source trajectory is commonly performed using an algorithm proposed by Feldkamp, Davis and Kress (FDK) in 1983. This reconstruction algorithm involves the rotation
