Abstract
Image reconstruction for multi-shot diffusion imaging requires accurate phase maps for each individual segment. Existing methods make use of 2Dnavigators [1] or self-calibrating trajectories to obtain low resolution phase maps. However, when the phase variations are not smooth enough compared to the resolution of the navigator, the resulting images are affected by phase cancellation artefacts. For this reason, an alternative reconstruction scheme was developed in this work, which allows to estimate high resolution phase maps. The method was applied to a segmented
