Abstract
A radiographic imaging apparatus includes a radiation detector () and a radiation source () which projects a non-parallel beam of radiation into field of view (). A footprint of each voxel (v) which is projected on the detector () is corrected based on the position of the voxel (v) in the field of view () in relation to the radiation detector () and the radiation source (). The contributions from substantially parallel redundant projections are further combined based on a fractional distance frac from a center point () of the voxel (v) to a center of each of the adjacent redundant projections.
