[Vv] Using vv/CLITK and elastix to compute target registration error

Dear VV community,

We are planning to get a radiologist to define corresponding landmarks on
fixed/moving inspiration/expiration CT lung images using VV. We use elastix
for image registration. Once the registration is performed, is it possible
to use VV/CLITK to compute the target registration error (TRE) between the
fixed image landmarks and the registered moving image landmarks?

Furthermore, we would like the landmarks to be defined on the moving image
prior to registration so that we can try different parameters to assess
which gives the best TRE. Perhaps this is outside the scope of the
mailbase, but has anyone done something similar using Elastix, where the
coordinates of the expert landmarks are defined prior to registration using
VV and new coordinates computed depending on the registration algorithm?

Best wishes,

Bilal Tahir,
