[Insight-users] deformation field for large shear in soft material

[H-B]

Hi Tim,
 
i am new like you to ITK, but as i know that Finite Element deformation more accurate than B-splain 
 
Good luck

Hi all,

I am trying to quantify the deformation of a soft tissue due to injurious stimuli. I am taking over some code left to me by a colleague that utilizes b-spline deformable registration tools, but there is clear mention of the limitations of this tool in circumstances where the object undergoes a lot of shearing motion.

Is there any way to get a reasonably accurate measure of the deformation field in instances of high shear, or is it that there is simply not enough mutual information between pre-deformation and post-deformation images to match up? Is there a certain strain (%) that the b-spline deformable registration tool can accommodate?

Any and all suggestions are very welcome - I'm also very new to the world of ITK.

Thanks greatly,
