Patent ID: 7778392

Claim:
A method for computed tomography (CT) volume reconstruction, the method comprising the steps of: A. during a precalculation phase, (i) determining a normalization to compensate for a non-circular orbit of a CT scanner; (ii) determining from one or more images acquired by the CT scanner of a known volume a weighting coefficient for each of one or more voxels of that volume; and (iii) determining an order in which to process two or more bricks of a volume to be reconstructed based at least in part on the proximity of said bricks to one another when images of the bricks are projected onto a detector plane, wherein each brick comprises voxels; B. during a runtime phase, (i) acquiring images from the CT scanner at one or more image locations of the volume to be reconstructed; and (ii) performing volume reconstruction from the images of the volume to be reconstructed utilizing a volume reconstruction algorithm and the steps of the precalculation phase.
