A magnetic resonance imaging (MRI) system and method are disclosed. The system includes: an independently arranged main magnet (30) and a gradient coil (40) and a radio frequency coil (50), both connected to a patient bed (60). A bore (100) is formed in a central portion of the main magnet (30), for containing the patient bed (60), the gradient coil (40) and the radio frequency coil (50). In this system, the gradient coil (40) and the radio frequency coil (50) are separated from the main magnet (30) instead of being integrated with the main magnet (30), thus avoiding making a patient claustrophobic feeling in a too narrow space. In addition, the system lowers the requirements on the magnet material and shielding space and thus leads to further reductions in costs and maintenance expenses.
