Expressions for the mean and variance of the images produced by Fourier multiaperture emission tomography are derived. Only quantum noise (counting statistics) is considered. The signal-to-noise ratio achieved by the system for a thin discshaped object is computed from these expressions. An example is used to demonstrate some significant features of this single photon emission tomographic imaging system.
