Abstract Conventional MRI (magnetic resonance imaging) equipments are usually bulky, expensive, large noise and difficult to set up, which limits their wide application. Low field mobile MRI devices are expected to solve these disadvantages. In the conventional magnetic resonance imaging, small sample is surrounded by a large magnet and the image is taken in the highly uniform magnetic environment (<5 ppm/40 mm DSV). The hardware design of the conventional magnetic resonance imaging and its corresponding technology are relatively mature and perfect. The open NMR (nuclear magnetic resonance) system is based on extremely inhomogeneous magnetic field conditions (>1000 ppm/mm DSV), and has a wide gap between the traditional hardware design and imaging techniques, and the difficulty is also increased dramatically. This paper reviews the origin, development and key technologies of the low field open magnetic resonance imaging technology, including hardware such as magnet, RF coil, gradient coil and method such as the design of radio frequency pulses, imaging sequence, image post processing. The aim of the review is to provide insights about the research and development of mobile MRI equipment.
