Liver segment registration and comparison

How to register two liver segmentation masks before to compare them?
In practis, I have liver segmentations masks from two different CT and I want to register this segmentations before to compare them (DICE comparisons and Hausdorff distances) with slicer RT.
I found how to register two exams but not two segmentation masks.
Can some one help me?

Hello @yann

There are a couple tools available to do this.

  1. Segment Registration module

(you have to install SlicerRT extension module )
  1. Surface registration module

( You will have to install CMFreg extension module for this)
