In this chapter, we will only concern our selves with the two most widely used algorithms in SPECT reconstruction, namely the FBP and Ordered-Subsets Expectation Maximization (OSEM) algorithms. This chapter describes the basic principles of these two algorithms, and summarises SPECT image attenuation and scatter correction methods. Finally, it presents a study evaluating the volumetric iterative reconstruction algorithm OSEM 3-D, and compares its performance with the FBP algorithm.
