Figure 1. CT Reconstruction Algorithms.

Figure 1

Schematic of the fast cone beam algorithm (FCBA; top) and the exact cone beam algorithm (ECBA; bottom), as detailed in Materials and Methods. Shown are the ray tracings from X-ray source to detector, along with their relationship to reconstructed voxels. Also shown are the CT detector binnings (for ECBA) used to create various detector sampling frequencies.
