There exist several reconstruction methods for computing a volumetric representation of a scanned object from a set of two-dimensional X-ray projection images. However, the most commonly applied method in practical cone-beam CT systems is the approximate FDK method. After we give some prerequisites that are necessary to understand the following descriptions, we present in Section 2.2 the FDK method, discuss possible implementation strategies (Section 2.2.2) that can be applied to practical cone-beam systems and analyze the time complexity of the involved algorithmic steps (Section 2.2.3).
