| 摘要 |
An MRI apparatus having a magnet structure which delimits a cavity for receiving a body under examination or a part thereof, which includes a mechanism for generating a magnetic field in the cavity, as well as a mechanism for causing the body under examination or the part thereof to emit nuclear magnetic resonance signals, a region defined in the cavity, known as an imaging volume, and a mechanism for receiving the nuclear magnetic resonance signals. The geometric center of the geometric shape of the cavity delimited by the magnet structure is offset in relation to the geometric center of the imaging volume. |
