摘要

Systems and methods for MBIR reconstruction utilizing a super- voxel approach are provided. A super- voxel algorithm is an optimization algorithm that, as with ICD, produces rapid and geometrically agnostic convergence to the MBIR reconstruction by processing super- voxels which comprise a plurality of voxels whose corresponding memory entries substantially overlap. The voxels in the super- voxel may also be localized or adjacent to one another in the image. In addition, the super- voxel algorithm straightens the memory in the "sinogram" that contains the measured CT data so that both data and intermediate results of the computation can be efficiently accessed from high-speed memory and cache on a computer, GPU, or other high-performance computing hardware. Therefore, each iteration of the super- voxel algorithm runs much faster by more efficiently using the computing hardware.
