Abstract
An imaging system is provided comprising an imaging magnet having a magnet bore . A plurality of passive shims is positioned within the magnet bore . A plurality of resistive shims is also positioned within the magnet bore . A plurality of thermometers is coupled thermally to a select number of the plurality of passive shims and read a passive shim temperature . A controller is in communication with the plurality of thermometers and the plurality of resistive shims . The controller includes logic adapted to adjust control currents sent to each of the plurality of resistive shims in response to the resistive shim temperatures received from each of the thermometers such that the strength of the magnetic field and its homogeneity is maintained.
