Abstract

An imaging system (702) includes a reconstructor (716) configured to reconstruct obtained cone beam projection data with a voxel-dependent redundancy weighting such that low frequency components of the cone beam projection data are reconstructed with more redundant data than high frequency components of the cone beam projection data to produce volumetric image data. A method includes reconstructing obtained cone beam projection data with a voxel-dependent redundancy weighting such that low frequency components are reconstructed with more redundant data than high frequency components to produce volumetric image data. A computer-readable storage medium, storing computer executable instructions, which when executed by a processor of a computer cause the processor to: obtain cone beam projection data and reconstruct the cone beam projection data with a voxel-dependent redundancy weighting such that low frequency components are reconstructed with more redundant data than high frequency components to produce volumetric image data.
