An automatic pre-emphasis based on the Gradient System Transfer Function (GSTF) was applied to real-time cardiac MR imaging at 3T to compensate for deviations of spiral k-space trajectories. This yielded cine series with coverage of the whole heart in free-breathing, less than 40 s total scan time and a temporal resolution of 50 ms. The developed framework was compared to a gated Cartesian acquisition in multiple breath-holds, in one healthy volunteer and one patient suffering from cardiac arrhythmia.
