Obtaining high quality images is very important in many areas of applied sciences. In this paper, we proposed general robust expectation maximization (EM)-Type algorithms for image reconstruction when the measured data is corrupted by Poisson noise. This method is separated into two steps: EM and regularization. In order to overcome the contrast reduction introduced by some regularizations, we suggested EM-Type algorithms with Bregman iteration by applying a sequence of modified EM-Type algorithms. The numerical experiments show the effectiveness of these methods in different applications. © 2011 Springer-Verlag.
