摘要

A system includes a single backprojector (120), which includes a single geometry calculator (204), at least one weight calculator (206), and a plurality of data interpolators (208). The single geometry calculator is configured to process scan parameters of a single computed tomography scan to generate geometry values only once for each voxel position in a volumetric image data matrix. The at least one weight calculator is configured to process the scan parameters of the single computed tomography scan and the geometry values to generate weight values for each voxel position in the volumetric image data matrix. Each of the plurality of data interpolators is configured to process, using the weight values and the same geometry values, a respective different type of projection data produced from the same single computed tomography scan to generate volumetric image data based on the volumetric image data matrix and corresponding to the respective different type of projection data.
