The paper introduces the first superconducting magnet system for whole body magnetic resonance imaging built in China. The character and composition of the system was described in detail. arm bore diameter of the magnet system is 1.08m, the length is 2.55m and total weight is 7000kg. The main magnet is composed of six superconducting coils and contributed 0.6T field. The coils are wound with NbTi wire with 1mm diameter and the rated current is 142.6A. Passive shims are used to correct the central field and achieve the uniformity of 2.5ppm in 30cm DSV. The cryostat system is equipped with LHe and LN2 closed-loop refrigerator which have been developed for MRI by CVI.
