[Insight-users] Insight-users Digest, Vol 117, Issue 3

[Tim Bhatnagar]

Thanks for your suggestions, Dr. Warfield.

For some reason I had thought that simply the existence of a deformation
field would allow the inverse to be calculated utilizing
inter/extrapolation, rather than requiring a meaningful Jacobian of the
inverse.

I will definitely be taking a look at the source code and perhaps trying an
implementation.

Thanks again,

Tim
