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.
