Gradient impulse response functions can predict gradient behavior in the presence of eddy currents and other sources of error. This work presents a rapid method for generating the 0th and 1st order gradient impulse response functions using existing software measurement techniques. The proposed method is applied to spiral imaging but could be similarly applied to EPI, projection reconstruction, or any other imaging sequence.
