An MRI system comprising compensating material located at a radial position between the imaging region and the magnet 10 in a location which will be heated over a range of temperatures during operation of the MRI system, said compensating material having a magnetic susceptibility which varies with temperature over the range of temperatures in a manner opposite to the variation in magnetic susceptibility of the material of the OVC bore tube over the range of temperatures. |
