Key Technologies and Development Prospects of Mobile Low-Field MRI Devices

Current clinical MRI systems are primarily high-field MRI systems, with foreign brands such as Siemens, Philips, and GE occupying over 70% of the domestic market share. These systems are expensive, have high operational costs and long imaging times. In contrast, low-field MRI devices have garnered significant attention in modern medicine in recent years due to their advantages, including quiet operation, rapid imaging, portability, and low cost. This study discussed the challenges in developing mobile MRI systems, focusing on image quality, low-frequency interference, and the trade-off between fast imaging and image clarity. It also analyzed the potential application scenarios of mobile MRI, proposing research strategies to address environmental noise elimination, AI-enhanced algorithms for rapid imaging, and image quality enhancement. These insights provide theoretical foundations and practical references for future advancements in portable MRI technology.
