ABSTRACT:
In a method for the compensation of disturbances due to vibrations in a magnetic resonance tomography apparatus s having a cryo-head seated on a cryostat for cooling a superconducting magnet and having a compensation device for correcting the magnetic field fluctuations generated due to the vibrations of the cryo-head, the compensation device sets the synthesizer frequency and/or the gradient currents according to the time curve of the field terms of the 0thand/or 1storders acquired in a tune-up.
