Principle and optimization analysis of electromagnetic devices for MRI

Currently, with the significant increase in global health awareness, people are paying more attention to various aspects of their health, thereby driving the demand for various types of medical devices. As an important medical diagnostic tool, Magnetic Resonance Imaging (MRI) has become more widely used in disease diagnosis. This paper primarily explores the basic working principles of MRI, its optimized design, and the challenges and prospects for its future development. First, the paper introduces the basic working principles of MRI’s electromagnetic apparatus, explaining the structure and functions of its five main components: the main magnet, gradient coils, radio frequency system, computer system, and magnet room, as well as how electromagnetic signals are used for imaging. Secondly, the article discusses the optimization of MRI in terms of structure, materials, and algorithms, aiming to improve the uniformity of magnetic field distribution, the accuracy of signal processing, and overall image quality. Finally, the paper analyzes the challenges facing the future development of MRI, such as high costs, complex equipment structures, and limited algorithmic technologies, and it looks ahead to the potential for achieving more efficient and broader applications through technological advancements.
