Abstract

Rician denoising is a mandatory task of Magnetic Resonance Imaging (MRI), as it enables higher-quality image processing, which is crucial for correct diagnosis. However, denoising is a slow task, especially because of the increased image resolution and the need for high image clarity. A solution towards this need is the implementation of rician denoise algorithm onto hardware. In this paper, we propose a hardware implementation of rician denoise, which processes the MR image into segments in a pipelined manner, while avoiding further processing on already denoised pixels of the image. Using a synthetic MRI scan separated into 16 segments, the proposed implementation achieves a speedup of 6.8x with comparable image quality, as compared to a software-only approach running on Intel Core2Duo.
