| 摘要 |
The present invention relates to a magnetic coil former (10) to be used in Magnetic Resonance Imaging (MRI) systems (12). A coil (14) is disposed on the former (10) and the former comprises a region of local stiffening provided by addition of extra material (22). The region of local stiffening corresponds to a region on the former (10) being exposed to stress caused by the magnetic field generated by the coils, the stress exceeding a safe stress limit, as determined using a finite element technique. |
