A method for analytically reconstructing a multi-axial computed tomography (CT) dataset, acquired using one or more longitudinally-offset x-ray beams emitted from multiple x-ray sources is provided. The method comprises acquiring one or more CT axial projection datasets, wherein the CT axial projection datasets are acquired using less than a full scan of data. The method further comprises reconstructing the CT axial projection datasets to generate a reconstructed image volume. The reconstruction comprises backprojecting one or more voxels comprising the multi-axial CT dataset, along one or more projection views, based upon a cone-angle weight determined for the voxels, wherein the cone-angle weight for the voxels is determined along a longitudinal direction.
