Iterative reconstruction of CT image - A revolutionary milestone in computed tomography?

Abstract

The article deals with basic principles and types of iterative reconstruction which are already available on recent CT scanners, commenting on their advantages and disadvantages. Differences between iterative reconstruction and filtered back projection considered as "gold standard" on all CT scanners for more than threee decades are also discussed.
