      abstract     = {Intensity interferometry is a well known method in
                      astronomy. Recently, a related method called incoherent
                      diffractive imaging (IDI) was proposed to apply intensity
                      correlations of x-ray fluorescence radiation to determine
                      the 3D arrangement of the emitting atoms in a sample. Here
                      we discuss inherent sources of noise affecting IDI and
                      derive a model to estimate the dependence of the signal to
                      noise ratio (SNR) on the photon counts per pixel, the
                      temporal coherence (or number of modes), and the shape of
                      the imaged object. Simulations in two- and three-dimensions
                      have been performed to validate the predictions of the
                      model. We find that contrary to coherent imaging methods,
                      higher intensities and higher detected counts do not always
                      correspond to a larger SNR. Also, larger and more complex
                      objects generally yield a poorer SNR despite the higher
                      measured counts. The framework developed here should be a
                      valuable guide to future experimental design.},
