Summary:PROBLEM TO BE SOLVED: To provide a method and apparatus for adjusting a center magnetic field of an MRI magnetic field generator relating to magnetic resonance image (MRI) imaging. SOLUTION: A product line of MRI systems includes a first MRI system (10) including a first yoke (12) and a plurality of magnet blocks (18) forming a first central assembly (30) disposed on the first yoke. The product line also includes a second MRI system (10) including a second yoke (12), a plurality of magnet blocks (18) forming a second central assembly (30) disposed on the second yoke and shaped the same as the first central assembly, and a first set of magnet blocks (32, 34, 36, 38, and 40) mounted to the second yoke at a periphery of the second central assembly.
