Three-Dimensional Fourier-Based Reconstruction Methods

Abstract

In this chapter, three-dimensional reconstruction methods will be discussed. The chapter starts in Sects. 8.2 and 8.3 with a description of pseudo three-dimensional methods that are based on stacks of two-dimensional images. The spiral CT method described in Sect. 8.3 also follows this pseudo three-dimensional approach, although in this case data acquisition is actually closer to a true three-dimensional reconstruction method. In this context, the term true means that the third dimension of the images is not the result of a secondary reconstruction inwhich the actual, i.e., primary, reconstruction only refers to two-dimensional Radon transforms.
