Reconstruction from Parallel-beam Projections

  • Robert Cierniak
Chapter

Abstract

Because of the performance limitations of scanners that used parallel beams of X-rays, engineers were obliged to modify the design of this system. However, the fact remains that all new generation CT scanners are based on parallel-beam image reconstruction algorithms. So, rather than algorithms dictated by the actual geometry of their projection systems, in most new image reconstruction techniques we use parallel beam methods.
