Claim 15:
16. An MRI system, comprising:
at least one magnetic field assembly that includes an open main magnet configured to generate a main magnetic field, a plurality of gradient coils configured to generate a gradient magnetic field, and a plurality of RF coils configured to generate a radio frequency magnetic field, the main magnetic field dominantly determining a magnetic resonance frequency; and
at least one image generator configured to generate a magnetic resonance image of an object by using the main magnetic field, the gradient magnetic field, and the radio frequency magnetic field generated by the at least one magnetic field assembly, wherein:
the open main magnet is disposed and fixed between adjacent examination rooms, and generates the main magnetic field while disposed between the adjacent examination rooms;
the main magnetic field generated by the open main magnet while the open main magnet is disposed between the adjacent examination rooms is commonly used in both of the adjacent examination rooms;
the open main magnet is disposed between a first examination room and a second examination room adjacent to each other, and configured to generate the main magnetic field common to the first examination room and the second examination room;
the plurality of gradient coils includes a first gradient coil configured to generate a first gradient magnetic field in the first examination room and a second gradient coil configured to generate a second gradient magnetic field in the second examination room;
the plurality of RF coils includes a first RF coil configured to generate a first radio frequency magnetic field in the first examination room and a second RF coil configured to generate a second radio frequency magnetic field in the second examination room;
the first examination room and the second examination room are adjacent to each other between upper and lower floors of a building; and
the open main magnet, the first gradient coil, the second gradient coil, the first Rf coil, and the second RF coils are disposed in a space between the first examination room and the second examination room or are buried in a floor or a ceiling between the first examination room and the second examination room.
