In the paper we show how to prospectively correct the motion-induced phase errors in Diffusion-Weighted SSFP using a fast real-time navigation system. The correction covers linear and constant phase terms, basically those arising from rigid-body motion. This is only one piece of the puzzle though; we still need to deal with the pulsing motion of the brain that causes non-linear errors…
