Methods and apparatus for compensating for drift in magnetic field strength in superconducting magnets |
摘要 |
An MRI system has compensating material located at a radial position between the imaging region and the basic field magnet in a location that will be heated over a range of temperatures during operation of the MRI system. The compensating material has a magnetic susceptibility that 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 of the basic field magnet over the range of temperatures. |
