3.2.22 Correction for B0 Distortion with B-Splines

<bspline_EPI_correction></bspline_EPI_correction>

  • on Default Setting
  • off

Perform bspline image registration based B0 susceptibility induced EPI distortion correction. Options are 'on' or 'off'. The default is 'on'.

Note: It is recommended that a fat saturated T2W structural image be provided for the EPI distortion correction to work appropriately. The contrast between the structures on T2W image lends itself to better EPI correction results. If T2W image is unavailable, EPI correction with T1W image can be attempted but we have not seen good results. Thus when using T1W or related contrast structural image, switch off the EPI correction option.
