Diffusion weighted imaging (DWI) has become indispensable in clinical routine, especially due to its sensitivity to early stages of brain ischemia. Patient motion during measurements is a major source of artifacts. There are different approaches to correct for rigid body motion depending on the type of motion. However, intrascan motion remains problematic for all of these correction methods. Even for single-shot EPI intrascan motion can lead to severe signal dropouts. This work presents a method to continuously apply prospective motion correction to correct for intra- and interscan motion with six degrees of freedom.
