ABSTRACT:
A technique is provided for improving consistency between slabs in a reconstructed CT image. Candidate sectors associated with an image slab are determined. If the sectors contain sufficient information to reconstruct the image slab, the sector which minimizes inconsistency with projection data for adjacent image slabs is selected for reconstruction. If the sectors do not contain sufficient information to reconstruct the slab, sectors are merged together until a merge group contains sufficient information. The merge group which minimizes inconsistency with projection data for adjacent image slabs is selected for image reconstruction. The selected sectors or merge groups are then reconstructed with the resulting image slabs comprising a reconstructed image with improved consistency between image slabs.
