We analyze the influence of diffraction caused by finite width of the pumping in quantum ghost imaging on the spatial resolution of produced ghost images. Following the necessary formal relations, we propose an algorithm for modeling and perform computer modeling. New variants of ghost imaging setups with spatial modulation of pumping phase are proposed. Their advantages are shown, and estimates of imaging resolution are provided.
