| 摘要 |
The invention relates to a magnetic resonance imaging apparatus (MRI apparatus) which is provided with an open magnet system and in which there are generated a basic magnetic field (vertical field) which perpendicularly traverses an object to be examined and also an RF field, which MRI apparatus is characterized notably in that coupling effects between a dipole structure (11, 12, 13), formed by the magnet system (10), and an RF conductor structure (20, 21, 22) are eliminated at least to a high degree by shifting or detuning a self-resonant frequency of the dipole structure relative to the MR frequency or by suppressing a self-resonant frequency of the dipole structure.
