The method includes pre-computing, by a computing device having a processor, a plurality of coefficients for a given two-dimensional point on which a voxel of a three-dimensional object is projected, based on integer parts of coordinates of surrounding two-dimensional points with respect to the given two-dimensional point. The plurality of coefficients lack inclusion of the coordinates. The method further includes storing, by a non-transitory storage device, the plurality of coefficients. The method additionally includes computing, by the computing device during a back-projection operation that forms a reconstructed three-dimensional image, an intensity value at the given two-dimensional point. The computing device computes the intensity value by reading the plurality of coefficients from the non-transitory storage device and combining the plurality of coefficients with the coordinates."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Efficient back-projection operation using precomputed table","description":"A method and system are provided.
