摘要： An MRI apparatus comprising a magnet structure which delimits a cavity for receiving a body under examination or a part thereof, and which includes means for generating a magnetic field in said cavity, as well as means for causing the body under examination or the part thereof to emit nuclear magnetic resonance signals, a region being defined in the cavity, known as imaging volume, and means for receiving the nuclear magnetic resonance signals. The MRI apparatus also comprises an electronic processing unit with which the means for receiving the nuclear magnetic resonance signals are electrically connected; the cavity has an access opening for receiving a body under examination or part thereof.The geometric center of the geometric shape of the cavity delimited by the magnet structure is in offset relation to the geometric center of the imaging volume.
