A theoretical acoustic noise control method was proposed
through gradient pulse alterations. This method can remove the resonant-frequency
components of the gradient pulse and keep the pulse form. This method is easily
implemented without reassembling the MRI system elements. Simulation shows that
the noise reduction effect using this method is significant. Imaging quality
will be evaluated on future experimental measurements.
