| 摘要 |
The invention provides a magnetic resonance imaging (MRI) device ( 21 ), comprising a diagnostic space ( 25 ), a main magnetic system ( 22 ) for generating a main magnetic field in said diagnostic space, a gradient magnetic coil system ( 23 ) comprising a gradient coil for generating at least one gradient of the main magnetic field, and noise reducing means ( 29, 32 ) for reducing noise that is generated as a result of vibrations of the gradient coil. The noise reducing means comprise a sound-absorbing panel ( 29 ) disposed between the gradient coil and the diagnostic space. The sound-absorbing panel ( 29 ) comprises channels having an open end and a closed end.
