N2 - Single-photon emission computed tomography (SPECT) is an inverse problem in which one wants to determine the distribution of a radionuclide from a set of measured projections. Like most inverse problems, it is ill-posed and does not admit of an exact solution. In this paper we review various methods from the literature on inverse problems that are applicable to SPECT. Topics considered include the discrete representation of continuous objects, the intrinsic dimensionality of an object, null functions, the role of prior information, and various reconstruction principles, including maximum likelihood, least squares, and Bayesian methods.
