Gradient impulse response function (GIRF) can be used to characterize gradient systems. GIRF measurements typically require multiple triangular waveforms of different durations to be played in three gradient axes. Using the traditional method, the entire measurement takes more than 10 hours. In this study, we propose an interleaved off-isocenter method to measure GIRFs. It can save nearly 50% of measurement time. The measured results are consistent with those measured using the time-consuming traditional method.
