Abstract
In this paper, we study the performance of an iterative algorithm for pinhole SPECT, in which the correction for pinhole blurring is realized by averaging multiple projection rays. In addition, we compare the effects of regularization obtained by using blob basis functions and voxels with and without post-smoothing.
