1. An image reconstruction method, comprising the acts of: accessing scan data acquired using a computed tomography system, wherein the scan data comprises temporally offset scan data; computing a voxel-dependent angular weighting function corresponding to the scan data; using the respective weighting function to iteratively compute a set of images from the scan data, such that the angular range of the data contributing to each voxel is made more uniform and/or the angular range is narrowed for one or more voxels; independently reconstructing images generated based on the temporally offset scan data to generate one or more temporally offset images; and combining the temporally offset images using one or more of averaging, addition, weighted combination, or Fourier combination.
