[Insight-users] MRI geometric distorsion

[Popa Teo]

Hi,
   
  Did anybody encounter geometric distorsion in MRI images,especially high-tesla(7) fields.I found that the geometric distorsion is quite obvious when I tried to measure the distance of 3 colinear fiducials with known distance on a in-plane slice.
   
  Does itk have methods for correcting this distorsion (especialy on 7T magnets for example ) or this should be done by manufacturer of MRI device?

  p.s.I know itk has some methods for correcting some characteristics of MRI images(like  MRI bias field correction itk::MIBiasFieldCorrectionFilter).
