Abstract
⺠Measurement of local perturbation fields (LPFs) on three different scanners. ⺠LPFs are, e.g., diffusion-gradient non-linearities/mis-calibration. ⺠LPFs bias fractional anisotropy (FA) and mean diffusivity (MD) maps. ⺠Correction improves accuracy, FA contrast and comparability between scanners. ⺠Relevant for group, longitudinal or multi-centre studies.
