摘要： A magnetic resonance imaging (MRI) system is provided. The system includes a main field magnet generating a main magnetic field B0. Moreover, the system further includes an integrated magnet device. The integrated magnet device has field-shift coils including primary field-shift coils and field-shift shield coils, the primary field shift coils being placed closer to an object to be imaged within the imaging volume than the field-shift shield coils. The gradient coils are placed between the primary field-shift coils and field-shift shield coils. At least one substrate layer is included to provide mechanical support for the field-shift coils and the gradient coils.
