In magnetic resonance imaging (MRI), noise filtering is very important as a pre-processing tool in image segmentation, which is useful for the detection of many diseases including brain tumors. Therefore, many studies have been conducted with an aim of reducing noise or artifacts, such as radio-frequency (RF) noise, motion, and chemical shift artifacts in MR images. Our research focused on the post-processing methods for removing RF noise which has a stripe-like shape and is caused by unwanted external RF signals. We first applied three well known de-noising methods (Adaptive Median Filter, Wiener Filter, and Lucy Richardson Method). After examining the effectiveness of these three de-noising methods, we finally proposed the use of the Interpolation method as a new de-noising method, which, as we found, is more intuitive and effective for RF noise removal than the conventional methods.
