  1. Each data frame contains 400 projections with 768 × 520 pixels. The reconstructed slices consist of 1024 × 1024 pixels. The reconstructed 3D preview consists of 128 × 128 × 128 voxels. Here, Process is the processing time for a single data frame, e.g. flat fielding and filtering. The total time to upload a data frame to the GPU is shown as Upload. The reconstruction time for processed data stored on the GPU for a 2D slice and a 3D preview is given as Slice and Preview respectively. Although many of the steps happen in parallel, a worst-case estimate for the processing of a single data frame and reconstruction of three arbitrary slices can be found by the sequential time computed as Process + Upload + Preview + 3 × Slice. This is estimate is shown as Total For Three Slices.
