Vibration compensation for nuclear spin tomograph involves setting synthesizer frequency and/or gradient currents according to time variation of zero, first order field terms derived during tuning |
摘要 |
The vibration compensation method involves compensating noise caused by vibrations with a compensating device for correction of magnetic field fluctuations generated by vibrations of a cooling head (2) for a superconducting magnet (1). The compensation device sets a synthesizer frequency and/or gradient currents according to the time variation of zero and first order field terms derived during tuning.
