| 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. | |||
