Abstract

The purpose of this study is to assess the effect of different noise reduction filters on medical images. In particular Computed Tomography (CT) and Magnetic Resonance (MR) images are analyzed because they represent the most used diagnostic techniques in radiologist field. In a first step the statistical properties of noise that affects CT and MR images are investigated. Then a denoising technique was applied on CT and MRI applications to show the differences in the performance of the proposed method and to highlight in both cases the limits and the advantages.
