Patent ID: 8655033

Claim:
An improved iterative reconstruction method to reconstruct a first image, the method comprising: generating an imaging beam; receiving said imaging beam on a detector array; generating projection data based on said imaging beams received by said detector array; providing said projection data to an image reconstructor; enlarging one of a plurality of voxels and a plurality of detectors of the provided projection data, wherein enlarging the plurality of voxels comprises modeling the plurality of voxels with an overlap between neighboring voxels, and wherein enlarging the plurality of detectors comprises modeling the plurality of detectors with an overlap between neighboring detectors; iteratively reconstructing portions of the first image with the plurality of enlarged voxels or detectors to create a reconstructed image; implementing non-uniform voxel sizes for the plurality of voxels; and implementing neighborhood dependent non-constant (NDNC) voxels for the non-uniform voxels.
