Abstract :
The purpose of this study is to assess the effect of different noise distribution on medical images. In particular Computed Tomography (CT) and Magnetic Resonance (MR) images are analyzed because they represent the most used diagnostic techniques in radiology. First of all the statistical properties of noise that affects CT and MR images are investigated. Then a new parameter able to compare the image quality for the two medical imaging techniques is proposed.
