Development of superconducting magnet for high-field MR systems in China

► Chronology of cryogenics, superconductivity and MRI systems research in China are reviewed. ► MRI superconducting magnet have many special requirements, such as homogeneity and drift. ► AllTech Medical Systems developed China's first large bore 50-cm DSV whole body 1.5 T MRI system. ► Key parameters of high-field superconducting magnet for MRI are studied.
