             abstract = "The diagnostic imaging by computed tomography has become popular 
                         in recent decades, causing concerns about the exposure of the 
                         human body to high doses of X-rays, which may cause cancer. Faced 
                         with this problem, studies are conducted with the objective of 
                         minimizing the dose of X-rays and maintain image quality since 
                         image degradation by noise reduction is proportional to the dose 
                         of X-rays. This paper proposes a methodology for 2D filtering 
                         noise made by Poisson projections using as a priori knowledge to 
                         the Wiener filter the result of filtering the projections by 
                         non-local filters after the stabilization of the noise variance by 
                         Anscombe transform.",
