Abstract: Magnetic Resonance Imaging (MRI) is beneficial and effective diagnostic tool in basic analysis, clinical investigation, and unwellness identification since it provides each chemical and physiological info regarding the tissue underneath investigation. however once noise get introduced in mister pictures, it decreases the image quality ,Image analysis and becomes tough to diagnose it accurately. A trade off between noise reduction and preservation of actual image options must build in such manner that enhance the diagnostically relevant image content. so noise reduction remains difficult task. This paper proposes wave domain denoising for removal of Rician noise from MR Image. This methodology heavily depends on alternative of threshold parameter that successively determines the potency of denoising.
