Gaussian Noise in Medical Imaging Systems: Sources, Effects, and Techniques for Mitigation

Abstract: Medical imaging has become a central element in modern medicine where it is used as the foundation of proper diagnosis and treatment plans. These imaging modes are desirable in terms of quality and reliability but even then, Gaussian noise continues to be a problem that reduces the crispness of the image thus leading to the inaccuracy of clinical interpretation. On the conclusions drawn in the above discussions, it is the purpose of this paper to give an exhaustive picture of Gaussian noise in medical imaging as informed by the results of this examination. It starts with naming the main origins of Gaussian noise, which are system limitations, motion of the patient and electromagnetic noise. Then the case is made to look at the effect of the Gaussian noise on the sensitivity of imaging, like ultrasound, CT, and MRI, which results in the loss of image contrast, poor yields of resolution and poor diagnostic capacity. In addition, the review also examines various mitigation measures, including measures that are software-related, including noise filters and machine learning algorithms, as well as solutions that are hardware-based and measures that are based on enhanced imaging. Finally, the present paper will also seek to provide an identifiable and concise general summary about any new information and methods on Gaussian noise in medical pictures with the goal of bettering the quality of medical pictures and provides greater accuracy to the contributions made to medical diagnosis. The results indicate that further innovation and interdisciplinary research should be conducted to create noise-reducing techniques, thus contributing to improving patient outcomes and the care they receive.
